[0009] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0010] FIG. 1 is a diagram showing an agricultural support system. The agricultural support system 1 includes a terminal device 10 operated by a user, and a server 100 for providing agricultural support to the user. The terminal device 10 is, for example, a mobile terminal such as a tablet, a smartphone, or a PDA. The terminal device 10 allows, for example, field information to be input by a user's operation. The field information includes map information of the field, geographical characteristics of the field, soil type of the field, and the like.

[0011] The terminal device 10 includes a control unit 11, a storage unit 12, a display device 13, a camera 14, and a second communication device 15. The control unit 11 controls various processes and functions of the terminal device 10. The control unit 11 is composed of electric and electronic circuits, a processor, a memory, and the like. The processor is, for example, a CPU (Central Processing Unit), a GPU (Graphics Processing Unit), a DSP (Digital Signal Processor), an FPGA (Field Programmable Gate Array), and an ASIC (Application Specific Integrated Circuit).

[0012] The storage unit 12 is a storage device such as a non-volatile memory, and stores various programs, various data, etc. The storage unit 12 is, for example, a hard disk drive (HDD) or a solid state drive (SSD).

[0013] Display device 13 is a liquid crystal display, organic EL display, or the like, having a display screen of a predetermined number of inches (for example, 10 inches). The size of display device 13 may be a size other than 10 inches. Camera 14 is a small camera (image sensor) with an effective pixel count of, for example, 10 million pixels and an autofocus function, and is capable of capturing an image of identification information CD of collection bag CB shown in FIG. 4 described below. Camera 14 may have specifications other than those described above, so long as it is capable of capturing an image of at least the identification information CD.

[0014] The second communication device 15 is configured as a device that performs short-distance or long-distance communication, and can be connected to the server 100. For example, the second communication device 15 is a device that performs wireless communication using Wi-Fi (Wireless Fidelity, registered trademark) of the IEEE802.11 series, which is a communication standard. The second communication device 15 may be a device that performs wireless communication using a mobile phone communication network, or a device that performs wireless communication using a data communication network.

[0015] The server 100 includes, for example, a control device 110 and a storage device 120. The control device 110 controls various processes, functions, and operations of the server 100. The control device 110 includes electric and electronic circuits, a processor, a memory, and the like. The processor is, for example, a CPU, a GPU, a DSP, an FPGA, an ASIC, and the like.

[0016] The storage device 120 is a storage device such as a non-volatile memory, and stores various programs (control programs, calculation programs, registration programs, etc.), various data, data tables, etc. The storage device 120 is, for example, an HDD, an SSD, etc.

[0017] The agricultural support system 1 includes a pre-treatment device 80 and a soil analysis device 90. The pre-treatment device 80 pre-treats the returned soil collected in the field. The soil analysis device 90 is a device that analyzes the returned soil collected in the field, and analyzes the pre-treated returned soil. The server 100 includes a first communication device 130, and is capable of communicating with the terminal device 10, the pre-treatment device 80, and the soil analysis device 90. Note that the agricultural support system 1 does not include the pre-treatment device 80 and the soil analysis device 90, and may be configured to be capable of communicating with at least the pre-treatment device 80 and the soil analysis device 90.

[0018] The first communication device 130 is configured as a device that performs short-distance or long-distance communication, and can be connected to external devices (such as the terminal device 10, the preprocessing device 80, and the soil analysis device 90). For example, the first communication device 130 is a device that performs wireless communication using Wi-Fi (Wireless Fidelity, registered trademark) of the IEEE802.11 series, which is a communication standard. The first communication device 130 may be a device that performs wireless communication using a mobile phone communication network, or a device that performs wireless communication using a data communication network.

[0019] The pretreatment device 80 is a device that pretreats recovered soil (e.g., a soil sample) collected in a farm field before the soil sample is analyzed by the soil analysis device 90. The pretreatment device 80 can also analyze (measure) the EC (electrical conductivity) and pH (hydrogen ion exponent) of the recovered soil (e.g., a soil sample). For example, the pretreatment device 80 generates a soil liquid by extracting components contained in the soil sample, and the soil liquid is placed in a liquid container (e.g., a cartridge).

[0020] The soil analysis device 90 is a device capable of analyzing (measuring) chemical components contained in the soil liquid placed in a cartridge by the pretreatment device 80, and is capable of measuring, for example, the content of nitrogen, phosphorus, and potassium, which are important elements for crop growth. The soil analysis device 90 is also capable of analyzing (measuring) calcium, magnesium, lime, potash, magnesia, lime / magnesium, magnesia / potassium, etc. The chemical components that can be analyzed by the soil analysis device 90 are merely examples and are not limited thereto. The soil analysis device 90 may also analyze (measure) EC and pH instead of the pretreatment device 80.

[0021] When performing analysis in the soil analyzing apparatus 90, the pretreatment device 80 places the pretreated soil and a component extracting liquid (a liquid for extracting components) in an extraction container in the pretreatment device 80 and shakes the extraction container. The shaken liquid (soil liquid) is filtered, and the filtered soil liquid is placed in a cartridge. The cartridge contains a reagent corresponding to the component to be analyzed, and the reagent reacts by mixing with the soil liquid inside the cartridge. The soil analyzing apparatus 90 measures the chemical components based on a change in color of the reagent that has reacted with the soil liquid. Note that the soil analyzing apparatus 90 described above is merely an example and is not limiting.

[0022] 2, the terminal device 10 can register a managed field map in the server 100, assist in sampling of soil from the registered field, and check the soil sampling history (including the progress of soil analysis). These operations are performed as follows.

[0023] First, the managed field map can be registered in the server 100 by operating the terminal device 10, as shown in Fig. 2. A specific application (e.g., a soil collection application) is pre-installed in the terminal device 10, and an icon corresponding to the soil collection application is displayed on the display device 13. When the user taps (touches) the icon, the terminal device 10 starts up the soil collection application and displays a login screen on the display device 13. The login screen displays an input section into which user information (e.g., a user ID and a password) can be input. When the user inputs the user information and taps the OK button, the second communication device 15 transmits the user information to the server 100.

[0024] The storage device 120 of the server 100 stores in advance account information (e.g., a user ID and a password) of a legitimate user. If the user information matches the account information of the legitimate user, the control device 110 of the server 100 permits login. In other words, the soil collection application becomes available on the terminal device 10. On the other hand, if the two do not match, the control device 110 does not permit login. In other words, the soil collection application is not available on the terminal device 10.

[0025] When login is permitted, the display device 13 of the terminal device 10 displays a main screen M1, as shown in Fig. 2. The main screen M1 includes a button MB1 that is selected when sampling soil, a button MB2 that is selected when registering a managed field map, and a button MB3 that is selected to record a soil sampling history.

[0026] Here, it is assumed that the user selects the button MB2 and the managed field map screen M2 is displayed. The user selects the new field creation button MB21 on the managed field map screen M2 to manage a new field (register a new field). The managed field map screen M2 displays a message saying "Please select a method for creating a new field" and various buttons MB21A, MB21B, and MB21C. The button MB21A is a cancel button. The button MB21B is a button for selecting a field that has already been registered in the farm management server (registering a field from the server 100). The button MB21C is a button for manually creating a plot. The farm management server is capable of field management, setting a crop plan, creating a work log, managing work progress, analyzing taste and yield, and the like, and can provide services to support agricultural management to users.

[0027] Here, the user selects button MB21C, and the display device 13 displays the partition creation screen M2A as shown in Fig. 3. The user touches and specifies predetermined points (e.g., four points at each corner) of the target field on the partition creation screen M2A. When the user finishes specifying all the predetermined points of the field and selects the partition confirmation button MB22A, the display device 13 displays the field information input screen M2B. The field information input screen M2B includes field information input items such as field name, soil type (e.g., sandy, loamy, clayey, etc.), planting / planned planting date, planting date, crop type, cultivation style, early / late maturity, shipping type, previous crop (incorporation), incorporation time, compost, and conventional compost input amount (kg / 10a). When the user finishes inputting these field information input items and selects the field information input completion button MB22B, the terminal device 10 accepts the field input information indicated by these field information input items. The second communication device 15 transmits the field input information to the server 100. The server 100 stores (registers) the received field input information in the storage device 120 in association with the field.

[0028] 2, the user can select a field that has already been registered in the farm management server and register at least the field map information (location information indicating the latitude and longitude of the field) in the server 100. Furthermore, if not only the field map information but also the field input information indicated by the above field information input items has already been registered in the farm management server, this field input information can also be registered in association with the field.

[0029] Next, a case where a user collects soil will be described. When collecting soil from the registered field, the user places the collected soil in a collection bag CB shown in Fig. 4 using a soil collecting tool. An identification label LB indicating identification information CD of the collection bag CB is attached to the collection bag CB. The identification information CD is, for example, a two-dimensional code, but may be a one-dimensional code or another type of code.

[0030] When the user selects the button MB1 on the main screen M1 shown in FIG. 5, the terminal device 10 activates the camera 14 and displays the read screen M3 for reading the code (identification information CD) of the collection bag CB on the display device 13. The terminal device 10 also displays an image captured by the camera 14 in the image display area of ​​the read screen M3 on the display device 13. The read screen M3 on the display device 13 also displays a message saying "Image the code". When the user photographs the identification information CD of the collection bag CB, the terminal device 10 displays the soil collection start screen M3A on the display device 13. The soil collection start screen M3A includes a message saying "Collect soil from several places in one field and put it in the same collection bag" and a message informing the collection points in the field (for example, five points in a diagonal method). When the user selects the collection start button MB11 on the soil collection start screen M3A shown in FIG. 5, the display device 13 displays the collection field selection screen M3B as shown in FIG. 6. The user selects the field selection button MB12 on the collection field selection screen M3B and moves to the collection point of that field.

[0031] As shown in Fig. 6, the display device 13 displays a collection point input screen M3B1. The user selects a registration button MB13 on the collection point input screen M3B1 to register the current location of the field as a collection location (collection point), and collects soil at this collection point using a soil collection tool and places it in a collection bag CB. The user performs this for each of the five collection points in order. The terminal device 10 has a positioning device that can detect its own position based on a positioning signal from a GPS (Global Positioning System) satellite, for example, and therefore can obtain location information indicating its own position. Therefore, the terminal device 10 can record the location information of the five collection points.

[0032] After the soil sampling at the five sampling points in the field is completed, the user uploads the data on the terminal device 10. The terminal device 10 collects the collected soil based on the upload operation. The location information of the field was associated with the identification information attached to the collection bag CB containing the collected soil. The collected information is transmitted to the server 100 by the second communication device 15 .

[0033] That is, the second communication device 15 transmits collection information that associates the location information of the field where the recovered soil was collected with the identification information CD attached to the collection bag (collection bag) CB in which the recovered soil is placed. The collection information is also transmitted in association with the user's account information (e.g., user ID and password).

[0034] The server 100 includes a registration unit 112. The registration unit 112 registers the collection information transmitted from the second communication device 15. The processor executes a registration program stored in the storage device 120, thereby functioning as the registration unit 112. Specifically, the registration unit 112 registers the setting information related to the crops and farm work in the field transmitted from the second communication device 15, and the analysis data obtained by analyzing the recovered soil in the collection bag CB by the soil analysis device 90, in association with the collection information.

[0035] The recovery bag CB containing the recovered soil is transported to an organization (such as a research institute, institution, or company) that has at least one or more pretreatment devices 80 and soil analysis devices 90. The organization may be, for example, the company's own organization, another company, a public organization, or a country. As will be described below, the recovered soil is pretreated in the pretreatment device 80, and then soil analysis is performed in the soil analysis device 90.

[0036] The pre-processing device 80 pre-processes the recovered soil in the recovery bag CB. When the pre-processing device 80 reads the identification information CD of the recovery bag CB, it issues a measurement lot number. Then, the pre-processing device 80 generates soil liquid by extracting components contained in the recovered soil in the recovery bag CB. Next, the pre-processing device 80 associates the measurement lot number with the liquid container containing the soil liquid, and outputs the measurement lot number, the identification information of the pre-processing device 80, and the measurement data of the soil liquid to the server 100 in association with the collection information. The registration unit 112 of the server 100 registers the measurement lot number from the pre-processing device 80, the identification information of the pre-processing device 80, and the measurement data of the soil liquid in association with the collection information.

[0037] When analyzing soil liquid, the soil analyzer 90 measures the measurement lot associated with the liquid container. The soil analysis device 90 reads the data of the soil liquid, and the soil analysis data of the soil liquid is The identification information of the analysis device 90 is output to the server 100 in association with the measurement lot number. The registration unit 112 of the server 100 receives the measurement lot number from the soil analyzer 90 and the 0's identification information and analysis data are linked to the collection information and registered.

[0038] The storage device 120 of the server 100 calculates the soil analysis result RT (see FIG. 11A). The server 100 includes a calculation processing unit 113. The calculation processing unit 113 calculates the analytical data, the calibration curve, and the correction data stored in the storage device 120. The soil analysis result RT is calculated based on the positive value. By executing the stored calculation program for calculating the analysis results, the calculation processing unit 113 and It functions as such.

[0039] When the calibration curve and / or the correction value is changed on the terminal device 10, the calculation processing unit 113 calculates the soil analysis result RT based on the analysis data and the changed calibration curve and / or the correction value.

[0040] In response to a request from the terminal device 10, the control device 110 of the server 100 generates screen data showing a display screen (see, for example, the progress screen M4 shown in FIG. 7) in which at least one of the progress statuses of pretreatment, analysis, and soil improvement proposals of the recovered soil is associated with each collection information. Then, the control device 110 causes the first communication device 130 to transmit the generated screen data to the terminal device 10. The terminal device 10 displays a display screen (progress screen M4) showing the progress status based on the screen data.

[0041] For example, when the button MB3 on the main screen M1 shown in Fig. 2 is selected by the user, the terminal device 10 transmits a request signal requesting the soil collection history to the server 100. In response to this request signal, the server 100 generates screen data showing the above-mentioned progress status and transmits it to the terminal device 10. The terminal device 10 receives the screen data and causes the display device 13 to display, for example, a progress screen M4 shown in Fig. 7.

[0042] For example, if the user of the terminal device 10 has the authority to check "AA" and "BB," the display device 13 of the terminal device 10 displays a progress screen M4 that lists information for the customer name "AA" and information for the customer name "BB." Specifically, as shown in Fig. 7, the progress screen M4 displays various information for each field name for the customer names "AA" and "BB." The various information includes the planned planting / sowing date, crop type, progress status, measurement lot (serial numbers of measurement devices such as the pretreatment device 80 and the analyzer), etc.

[0043] 7, the progress status on the progress screen M4 includes "Waiting for analysis", which indicates that soil analysis is pending, "Analyzed", which indicates that soil analysis has been completed, "Proposed", which indicates that a proposal for soil improvement has been submitted, etc. The progress status may further include "Waiting for preprocessing", which indicates that preprocessing by the preprocessing device 80 is pending. In this case, "Waiting for analysis" means that soil analysis is pending after preprocessing.

[0044] When the user of the terminal device 10 is only "AA", a progress screen M4 consisting only of information that the customer name is "AA" is transmitted from the server 100 and displayed on the display device 13 of the terminal device 10. The progress screen M4 may also include information that the customer name is "AA", and information that the customer name is "BB" may be masked (blurred) so that it cannot be seen.

[0045] When an instruction to rearrange the order of the progress status is received, the control device 110 of the server 100 The screen data showing the display screen rearranged in the order of the progress status is transmitted to the terminal device 10. The display device 13 of the terminal device 10 displays the progress status in order of "waiting for analysis", "analyzed", "proposed", " The display device 13 displays a screen in which the items are rearranged in the order of "read" or the reverse order. Items other than the progress status, such as customer name, field name, planned planting / sowing date, crop type, measurement log The display may be rearranged in response to an instruction to rearrange any of the items. The terminal device 10 may generate and display a display screen in which the progress statuses are rearranged in the designated order. good.

[0046] Furthermore, the agriculture support system 1 can propose the field soil analysis result RT and soil improvement proposal SP to an authorized user (for example, the person who registered the field and collected soil and related parties as shown in Figs. 2 to 6) through the terminal device 10. That is, the authorized user can receive the field soil analysis result RT and soil improvement proposal SP on the terminal device 10. The soil improvement proposal SP by the agriculture support system 1 is carried out as follows.

[0047] The terminal device 10 transmits the user's account information to the server 100 in association with the collected information. The control device 110 of the server 100 receives the user input information input from the terminal device 10. If the information matches the account information registered in the registration unit 112, the soil analysis result R T and the soil improvement proposal SP are transmitted to the terminal device 10 by the first communication device 130.

[0048] The server 100 includes an acquisition unit 111. The acquisition unit 111 acquires soil analysis information of the field, including field information, crop information, measurement data (EC (electrical conductivity) and pH (hydrogen ion exponent)) from the pretreatment device 80, and analysis data of the recovered soil from the soil analysis device 90. The processor executes a control program stored in the storage device 120, thereby functioning as the acquisition unit 111.

[0049] The control device 110 specifies the fertilization standard for the field based on the soil analysis information acquired by the acquisition unit 111. For example, the storage device 120 stores in advance a plurality of fertilization standards according to crops for each region. The control device 110 specifies the fertilization standard corresponding to the contents of the soil analysis information from among the plurality of fertilization standards stored in the storage device 120.

[0050] Multiple fertilization standards are based on one or more areas (e.g. prefectures) in a map and the soil type (e.g. sand, quality, soil quality, clay, etc.) and crop information (e.g. type of crop grown in the area and cultivation method The fertilization standards are assigned to each combination of the cultivation method. There are tunnels such as vinyl tunnels and greenhouses. There are multiple fertilizer standards, depending on the prefecture and the crop. Those that have all three of the above, namely, the crop type and the cultivation method, and those that have only two of the prefecture and the crop type or the cultivation method. For example, the "Tokushima Prefecture: Carrot: Tunnel" project has all three. Fertilization standards for "Aomori Prefecture: Carrots: Outdoor" and "Ehime Prefecture: Carrots: Tunnel" The fertilization standards are as follows: For example, the fertilization standards for "Shimane Prefecture: Carrots", "Iwate Prefecture: Carrots", and These are the fertilization standards for "Akita Prefecture: Carrots". 0. Note that the crop information is stored in either the crop type or the cultivation method. It is also possible to use the following.

[0051] Furthermore, the storage device 120 stores area and crop information in a weighted manner. For example, the weighting values ​​for the area and crop information are: area = 10 points > crop information (crop type = 7 points). > It is related to crop information (cultivation method = 5 points), but there are other combinations. The weighting value may be set to a different value. It includes crop information and field soil type.

[0052] In addition, multiple fertilization standards are based on the area (e.g. prefecture) and crop information (e.g. crop type and Fertilization according to the combination of the cultivation method and the soil type of the area (e.g. sand, loam, clay, etc.) In this case, the storage device 120 stores the area, the soil type, and the crop. The weights of the area, soil type, and crop information are stored. = 10 points > Crop information (crop type = 7 points) > Crop information (cultivation method = 5 points) > Soil type (3 points) ), but other combinations are also possible, and the weights may be different from those. Other values ​​are also acceptable.

[0053] The control device 110 specifies the fertilization standard with the highest total score that matches the contents of the soil analysis information from among the multiple fertilization standards. For example, if the contents of the soil analysis information are "Tokushima Prefecture: Carrots: Tunnel", the total score of the weighted value of the fertilization standard of "Tokushima Prefecture: Carrots: Tunnel" is 22 points (=10 points+7 points+5 points). The total score of the weighted value of the fertilization standard of "Aomori Prefecture: Carrots: Open Field", which differs only in prefecture, is 12 points (=0 points+7 points+5 points). The total score of the weighted value of the fertilization standard of "Tokushima Prefecture: Carrots", which has no cultivation method, is 17 points (=10 points+7 points). The total score of the weighted value of the other fertilization standards is less than 22 points. Therefore, the control device 110 selects the fertilization standard with the highest total score of the weighted value (here, the fertilization standard of "Tokushima Prefecture: Carrots: Tunnel").

[0054] The server 100 includes a soil improvement proposal calculation unit 114. The soil improvement proposal calculation unit 114 calculates a soil improvement proposal SP so that the soil analysis result RT of the field calculated from the analysis data of the recovered soil by the soil analyzer 90 falls within the soil standard range value indicated by the specified fertilization standard. The processor executes a calculation program for soil improvement proposal stored in the storage device 120, thereby functioning as the soil improvement proposal calculation unit 114.

[0055] The first communication device 130 of the server 100 transmits the soil analysis result RT and the soil improvement proposal SP to the terminal device 10.

[0056] The soil improvement proposal calculation unit 114 calculates one or more soil improvement proposals SP, and when low cost priority is selected, selects a first soil improvement proposal with the lowest cost (expenses, price, etc.) from among the one or more soil improvement proposals SP. Also, the soil improvement proposal calculation unit 114 calculates one or more soil improvement proposals SP, and when labor-hour reduction priority is selected, selects a second soil improvement proposal with the least number of tasks from among the one or more soil improvement proposals SP.

[0057] The following describes the operating procedure when an authorized user (sometimes simply referred to as a user) receives soil analysis results RT and soil improvement proposals SP. Assume that the user selects the third display data from the top on the progress screen M4 shown in Figure 8 (i.e., the display data whose progress status is "analyzed"). This third display data is the customer name "AA", the field name "230613_KBT Test (carrot) field", the planned planting / sowing date "2023 / 06 / 28", the crop "carrot", the progress status "analyzed", and the measurement lot "20230613-01".

[0058] The display device 13 of the terminal device 10 displays information about the display data selected by the user in a display area AR1 at the right edge of the progress screen M4 shown in Fig. 8. A button MB4 saying "Perform soil diagnosis" is displayed at the bottom of the display area AR1. When the user selects button MB4, the server 100 displays a pop-up screen PG1 on the display device 13, which shows the conditions for performing a soil diagnosis.

[0059] Specifically, the display device 13 displays a pop-up screen PG1 indicating the soil diagnosis standard and the fertilization standard on the progress screen M4, as shown in Fig. 9. Here, the pop-up screen PG1 displays the soil diagnosis standard and the fertilization standard selected by the control device 110. The soil diagnosis standard is that the cultivation area is Tokushima Prefecture, the crop is "carrots", and the fertilization standard is that the cultivation area is Tokushima Prefecture, the crop is "carrots", and the cultivation style is tunnel.

[0060] The control device 110 of the server 100 searches for information that matches the field information (geographical characteristics of the field, soil type, etc.) and crop information (crop variety, cultivation method, etc.) contained in the managed field map registered by the user in the server 100 among multiple criteria (e.g., multiple soil diagnosis criteria and multiple fertilization criteria) stored in the memory device 120, and selects the most matching criteria (soil diagnosis criteria and fertilization criteria).

[0061] The control device 110 automatically selects one by one the "soil diagnosis standard" and "fertilization standard" that best match the conditions (crop, cultivation method, soil type, etc.). For example, the control device 110 selects the soil diagnosis standard and fertilization standard based on the managed field registration (prefecture, cultivation method, soil type, etc.) shown in Figures 2 and 3. The control device 110 weights the conditions (prefecture, cultivation method, soil type, etc.) and gives priority to selecting the one with the matching prefecture.

[0062] In the managed field maps shown in Figures 2 and 3, the cultivation area is registered as Tokushima Prefecture, the crop is "carrots", and the cultivation method (style) is tunnel. Therefore, the control device 110 selects the soil diagnosis criteria when the cultivation area is Tokushima Prefecture and the crop is "carrots". In other words, it selects the soil diagnosis criteria with the largest sum of weight values. The control device 110 also selects the fertilization criteria when the cultivation area is Tokushima Prefecture, the crop is "carrots", and the cultivation method (style) is tunnel. In other words, it selects the fertilization criteria with the largest sum of weight values.

[0063] It should be noted that, as shown in Fig. 10, the fertilization standard can be changed by a selection operation of the user. When the fertilization standard is changed to "Aomori Prefecture: carrots: outdoor field", the control device 110 accepts the changed fertilization standard.

[0064] The pop-up screen PG1 shown in FIG. 9 displays a button MB5 indicating "Yes." When the user selects the button MB5, the control device 110 of the server 100 performs soil diagnosis using the soil diagnosis criteria and fertilization criteria displayed on the pop-up screen PG1. The control device 110 transmits a soil diagnosis table SD (see FIG. 11A and FIG. 11B) including the calculated soil improvement proposal SP and fertilization criteria to the terminal device 10. FIG. 11A is a diagram showing an example of the first half of the soil diagnosis table. FIG. 11B is a diagram showing an example of the second half following the first half of the soil diagnosis table shown in FIG. 11A. The display device 13 of the terminal device 10 displays the soil diagnosis table SD as shown in FIG. 11A and FIG. 11B.

[0065] The soil diagnosis table SD contains the soil analysis results RT (items, units, measurements) as shown in Fig. 11A. The soil analysis results RT include items such as pH, available phosphate (phosphate), exchangeable potassium (potassium), exchangeable lime (lime: calcium), exchangeable magnesium (magnesium: magnesium), lime / magnesium, magnesium / potassium, EC, and nitrogen, as well as units and measurements.

[0066] Furthermore, the soil diagnostic standard value SV is displayed to the right of the soil analysis result RT in the soil diagnostic table SD. The soil diagnostic standard value SV is displayed as standard range values ​​for pH, available phosphate, exchangeable potassium, exchangeable lime, exchangeable magnesium, lime / magnesium, and magnesium / potassium. A comparison display area DA is displayed to the right of the soil diagnostic standard value SV, showing the relationship between the measured value displayed in bar graph format and the soil diagnostic standard value SV. For example, the comparison display area DA displays each measured value as a black line bar graph, and displays the range frame of the soil diagnostic standard value SV. By looking at the comparison display area DA, the user can confirm whether the measured value is within the range frame (range frame showing within the standard) indicating the standard range of the soil diagnostic standard value SV. It can be seen that the measured values ​​of pH, exchangeable potassium, exchangeable lime, exchangeable magnesium, and magnesium / potassium are within the standard, and the measured values ​​of available phosphate and lime / magnesium are outside the standard.

[0067] That is, the comparison display area DA displays the soil improvement proposal SP for improving the soil to the standard range of the soil diagnostic standard value SV. For example, the predicted value after fertilization based on the fertilization proposal FP described later is displayed in hatched form. According to this, the measured values ​​of available phosphate and lime / magnesium, which were outside the standard, are predicted to fall within the standard.

[0068] The control device 110 identifies the fertilization standard with the highest total score that matches the contents of the soil analysis information from among the multiple fertilization standards. Here, the contents of the soil analysis information are "Tokushima Prefecture: Carrots: Tunnel", and as described above, the total weighted value score of the fertilization standard "Tokushima Prefecture: Carrots: Tunnel" is 22 points, which is higher than the total weighted value scores of the other fertilization standards. Therefore, the control device 110 identifies (selects) the fertilization standard with the highest total weighted value score (here, the fertilization standard "Tokushima Prefecture: Carrots: Tunnel"). The display device 13 of the terminal device 10 displays this identified fertilization standard as shown in FIG. 11B. This fertilization standard includes fertilization with nitrogen of "18.0", phosphorus of "20.0", and potassium of "22.0" as shown in FIG. 11B.

[0069] In addition, the soil improvement proposal calculation unit 114 calculates one or more soil improvement proposals SP, and when low cost priority is selected, selects the first soil improvement proposal with the lowest cost among the one or more soil improvement proposals SP. Here, the soil improvement proposal calculation unit 114 selects the soil improvement material proposal SP1 shown in FIG. 11B as the first soil improvement proposal, and includes it in the soil diagnosis table SD. In FIG. 11B, the soil improvement material proposal SP1 includes two materials (for example, "first material" and "second material"). For these two materials, information such as the material name ("first material" and "second material"), fertilizer amount per tan, fertilizer amount per planted area, number of bags, nitrogen, phosphorus, potassium, lime, magnesia, and planted area price is included.

[0070] In addition, the soil improvement proposal calculation unit 114 calculates one or more soil improvement proposals SP, and when the labor reduction priority is selected, selects the second soil improvement proposal with the least number of operations from among the one or more soil improvement proposals SP. For example, when the soil improvement proposal calculation unit 114 selects a soil improvement material proposal SP1 with one operation as the second soil improvement proposal, it includes it in the soil diagnosis table SD shown in Fig. 11B. This second soil improvement proposal is a soil improvement material proposal SP1 with only one material, and includes information such as the name of one material, the amount of fertilizer per tan, the amount of fertilizer applied per planted area, the number of bags, nitrogen, phosphorus, potassium, lime, magnesium, and the planted area price.

[0071] The control device 110 may include an acquisition unit 111, a registration unit 112, a calculation processing unit 113, and a soil improvement proposal calculation unit 114.

[0072] Furthermore, the agriculture support system 1 can create a soil score map SMP1 based on the soil diagnosis result, as shown in FIG.

[0073] The server 100 includes a creation unit 115. The creation unit 115 calculates a soil score indicating an evaluation of the soil of the field based on the soil analysis result RT of the field, and creates a soil score map SMP1 showing the field in a display mode according to the soil score. The processor executes a score map creation program stored in the storage device 120, thereby functioning as the creation unit 115.

[0074] For example, the creation unit 115 calculates a soil score by converting the soil of the field into a score based on the soil analysis result RT of the field, and creates a soil score map SMP1 showing the field in a display mode according to the soil score.

[0075] Specifically, as shown in FIG. 13, the creation unit 115 calculates a soil score by assigning a score to the soil of the field based on the soil component values ​​(measured values) of the field included in the soil analysis result RT and predetermined reference values.

[0076] In FIG. 13, the soil component values ​​(measured values) are four: phosphoric acid, potassium, lime, and magnesium. In addition, there are standard values ​​for each of phosphoric acid, potassium, lime, and magnesium. Each standard value is a value in a predetermined range from a lower limit to an upper limit. If the measured value is within the standard value, the measured value is given full marks (for example, 25 points). On the other hand, if the measured value is outside the standard value, the measured value is given a score obtained by subtracting a certain number of points from the full mark (or the more the measured value is deducted, the more the measured value is deducted). In other words, the score differs depending on whether the measured value is within the standard value or not. In addition, the full mark is set to the median of the standard value, and the more points are deducted as the measured value deviates from the median, but the upper or lower limit is considered a passing mark, and the more points are deducted as the measured value deviates from the median, the more the measured value is not the standard value, and the more points are deducted as the measured value deviates from the median, resulting in a failing mark.

[0077] In Figure 13, of the four soil component values ​​(measured values) for Field 1, only phosphate is within the standard value, so phosphate receives full marks (25 points). On the other hand, potassium, limestone, and magnesium are outside the standard values, so if a fixed deduction method (15 points) was used, each would receive 10 points. As a result, the soil score for Field 1 would be 55 points (= 25 points + (10 points x 3)). On the other hand, if a proportional deduction method was used, the scores for potassium, limestone, and magnesium would be 15 points, 10 points, and 15 points, so the soil score for Field 1 would be 65 points (= 25 points + 15 points + 10 points + 15 points).

[0078] For the second field, since the phosphate, potassium, and lime are within the standard values, the soil is given a full score (25 points), but since the magnesium is outside the standard values, if a fixed deduction method (15 points) was used, the soil would be given 10 points, and the soil score for the second field would be 85 points (= (25 points x 3) + 10 points). On the other hand, if a proportional deduction method was used, the magnesium would be given 20 points, and the soil score for the second field would be 95 points (= (25 points x 3) + 20 points). The creation unit 115 may determine that the soil score is good if it is equal to or above a threshold score (for example, 75 points). The above examples of calculations for soil scores are merely examples, and are not intended to be limiting.

[0079] The creation unit 115 creates a soil score map SMP1 that shows the field in a display mode (e.g., color, pattern, score, etc.) according to the soil score. For example, if the soil score is equal to or greater than a threshold score (e.g., 75 points), the creation unit 115 displays the field in green, indicating "good," if the soil score is less than 75 points but equal to or greater than 55 points, in blue, indicating "slightly poor," and if the soil score is less than 55 points, in purple, indicating "poor." The creation unit 115 may also use a display mode with different shades (e.g., a certain shade indicates good, and the deeper it is, the worse it is).

[0080] The creation unit 115 may also store sign information, such as "+" when the measured value exceeds a reference value and "-" when the measured value falls below the reference value, together with the score. The creation unit 115 may determine that the soil component value is in an excess state when there are many "+"s and that the soil component value is in a shortage state when there are many "-"s. The creation unit 115 displays the field in a green display mode if there is no bias between "+"s and "-"s and the soil score is equal to or greater than a threshold score. The creation unit 115 may also display the field in a display mode that changes from yellow to red as there are more "+"s and the soil score is lower than the threshold score, and changes from blue to purple as there are more "-"s and the soil score is lower than the threshold score. The above display modes and threshold scores are merely examples and are not intended to be limiting.

[0081] Furthermore, the creation unit 115 may create a soil score map SMP1 that shows the field in a display mode (e.g., color, pattern) according to the soil score, and also shows the soil score points as additional information, as shown in Fig. 13. Alternatively, the creation unit 115 may create a soil score map SMP1 that shows the field in a display mode (e.g., score) according to the soil score.

[0082] The first communication device 130 of the server 100 transmits the soil score map SMP1 to the terminal device 10. The display device 13 of the terminal device 10 displays the soil score map SMP1.

[0083] Furthermore, when a field (e.g., the first field) is selected in the soil score map SMP1, the creation unit 115 creates comparative display data DD1 showing the relationship between the soil component values ​​of the selected field (e.g., the first field) and the reference values. The first communication device 130 transmits the comparative display data DD1 of the first field to the terminal device 10. In Fig. 13, the comparative display data DD1 showing the relationship between the soil component values ​​and the reference values ​​for the first field and the second field is displayed, but this corresponds to displaying the comparative display data only for the first field.

[0084] When multiple fields are selected on the soil score map SMP1, the creation unit 115 creates comparison display data DD1 showing the relationship between the soil component values ​​of the selected multiple fields and the reference values. The first communication device 130 transmits the comparison display data DD1 to the terminal device 10. For example, as shown in Fig. 13, when a first field and a second field are selected by the user, the creation unit 115 creates comparison display data DD1 showing a comparison between the fields.

[0085] Furthermore, the agriculture support system 1 can create a yield score map SMP2 shown in FIG. 14, a fertilizer cost score map SMP3 shown in FIG. 14, a farm field quality score map SMP4 shown in FIG. 15, and the like.

[0086] The storage device 120 of the server 100 stores the yield of each field in advance. The control device 110 of the server 100 may access the farm management server to obtain the yield of the field. The creation unit 115 calculates a yield score indicating an evaluation of the yield of the field based on the yield of the field. For example, the creation unit 115 calculates the yield score based on a predetermined yield reference value (e.g., a target yield) of the field and the actual yield. Specifically, the creation unit 115 may calculate the yield score as yield score = yield / target yield. If the yield is "70 kg / 10a" and the target yield is "100 kg / 10a", the yield score is 70% (which can also be said to be "-30%" when 100% is used as the standard). In addition, if the yield is "115 kg / 10a" and the target harvest yield is "100 kg / 10a", the yield score is 115% (which can also be said to be "+15%" with 100% as the standard). The creation unit 115 creates a yield score map SMP2 that shows the field in a display mode according to the yield score, as shown in FIG.

[0087] The storage device 120 of the server 100 stores the area and fertilizer cost of each field in advance. The control device 110 of the server 100 may access the farm management server to acquire the area and fertilizer cost of the field. The creation unit 115 calculates a fertilizer cost score indicating an evaluation of the fertilizer cost of the field based on the fertilizer cost of the field. For example, the creation unit 115 may determine the fertilizer cost score by dividing the fertilizer cost, which is the purchase price of the fertilizer used in the field, by the field area and multiplying the result by the reference area. If the price of the fertilizer used in a field with an area of ​​"20a" is "6000 yen", the creation unit 115 calculates that the fertilizer cost is "3000 yen / 10a" using the formula (fertilizer price "6000 yen" / field area "20a") x reference area "10a".

[0088] The creation unit 115 creates a fertilizer cost score map SMP3 that shows the field in a display mode according to the fertilizer cost score. For example, when the value of the fertilizer cost score is the normal cost score (for example, 3000 yen ± 500 yen / 10a), the creation unit 115 displays the field in green. Furthermore, the creation unit 115 displays the field in a display mode in which the color of the field changes from yellow to red as the value of the fertilizer cost score becomes smaller than the normal cost score. Furthermore, the creation unit 115 displays the field in a display mode in which the color of the field changes from blue to purple as the value of the fertilizer cost score becomes larger than the normal cost score. Thus, the creation unit 115 creates a fertilizer cost score map SMP3 in such a display mode.

[0089] The display form is not limited to colors, and may be patterns, numerical values, or symbols (for example, symbols such as ◎, ◯, and ×). The creation unit 115 creates a fertilizer cost score map SMP3 showing the field in a display form according to the fertilizer cost score, as shown in Fig. 14.

[0090] The creation unit 115 calculates a yield score by converting the yield of the field into a score based on the yield of the field and a predetermined yield reference value (e.g., a target harvest yield) as described above. The creation unit 115 also calculates a fertilizer cost score by converting the fertilizer cost of the field into a score based on the fertilizer cost of the field and a predetermined fertilizer cost reference value (e.g., the above fertilizer price / field area) as described above. The creation unit 115 then generates a field quality score map SMP4 shown in Fig. 15 that shows the field in a display mode according to the yield score and fertilizer cost score.

[0091] Specifically, as shown in FIG. 15, there are five types of yield scores for a field, for example, "+10% or more," "+5 to +10%, "-5 to +5%, "-10 to -5%, "-10% or less." The creation unit 115 creates a yield score map SMP2 showing the field in a display mode corresponding to the five types of yield scores. As shown in FIG. 15, there are three types of fertilizer cost scores, for example, "lower by 10% or more," "within ±10%," and "higher by 10% or more" than the average fertilizer application cost per 10a. The creation unit 115 creates a fertilizer cost score map SMP3 showing the field in a display mode (for example, symbols such as ◎, △, and ×) corresponding to the three types of fertilizer cost scores. The creation unit 115 overlays the yield score map SMP2 and the fertilizer cost score map SMP3 to generate a field quality score map SMP4 shown in FIG. 15.

[0092] 15, when a user selects any field on the field quality score map SMP4, the terminal device 10 transmits a signal requesting a radar chart of the field to the server 100. The server 100 transmits display data showing the radar chart of the field to the terminal device 10. The terminal device 10 receives the display data and causes the display device 13 to display a radar chart showing the actual measurement results before fertilization and the predicted values ​​after fertilization based on the fertilization proposal for the field selected by the user.

[0093] Furthermore, as shown in FIG. 12, the agriculture support system 1 is capable of controlling fertilization by a fertilizer applicator 30 (eg, a fertilizer broadcaster), which is an example of an implement, based on a fertilization proposal FP calculated from the soil analysis result RT.

[0094] The server 100 includes a fertilization proposal calculation unit 116. The fertilization proposal calculation unit 116 calculates a fertilization proposal FP for the materials and fertilizer amounts to be applied in the field based on the soil analysis results RT. The above processor executes a calculation program for fertilization proposal calculation stored in the storage device 120, thereby functioning as the fertilization proposal calculation unit 116. The fertilization proposal FP calculated by the fertilization proposal calculation unit 116 includes, for example, a base fertilizer proposal FP1 shown in FIG. 11B. The base fertilizer proposal FP1 (fertilization proposal FP) shown in FIG. 11B includes, for example, two materials (for example, "material G5" and "material K8"). For these two materials, information on the material name ("material G5" and "material K8"), fertilizer amount per tan, planted area fertilizer amount, number of bags, nitrogen, phosphorus, potassium, lime, magnesium, and planted area price is included. The first communication device 130 transmits a fertilization proposal FP for the field to the fertilizer applicator 30.

[0095] The fertilization proposal calculation unit 116 calculates the aperture setting of the spray nozzle for spraying the material to the field, based on the material and the amount of fertilizer to be applied in the field and the area of ​​the field, as the fertilization proposal FP. Specifically, the fertilization proposal calculation unit 116 includes the aperture setting of the spray nozzle for spraying the material to the field, based on the material and the amount of fertilizer indicated by the selected fertilization proposal FP (for example, the base fertilizer proposal FP1 shown in FIG. 11B) (i.e., the material and the amount of fertilizer to be applied in the field) and the area of ​​the field, in the fertilization proposal FP.

[0096] Here, an example will be described in which the fertilization proposal FP shown in Fig. 11B is the base fertilizer proposal FP1 (fertilization proposal FP) shown in Fig. 16. The base fertilizer proposal FP1 shown in Fig. 16 is a proposal for field H11, for example, and includes information such as the application time being immediately before sowing, the type being base fertilizer, the product name being material A, and the amount of fertilizer to be applied per tan being "15.0 kg / 10a."

[0097] The fertilization proposal calculation unit 116 calculates the aperture setting of each spray nozzle that sprays each material on the field as a fertilization proposal FP based on multiple materials to be fertilized in the field, the fertilizer amount for each material, and the area of ​​the field. Note that the fertilization proposal calculation unit 116 may calculate a fertilization proposal FP for a single material when labor reduction priority is selected, and may calculate a fertilization proposal FP for multiple materials when low cost priority is selected.

[0098] For example, in the case shown in Fig. 16, the fertilization proposal calculation unit 116 identifies the material to be fertilized in the field H11 as "material A" and the fertilizer amount of material A (e.g., fertilizer amount per tan) as "15.0 kg / 10a" based on the base fertilizer proposal FP1 shown in Fig. 16, and calculates the aperture setting of the spray nozzle that satisfies the fertilizer amount per tan for the area of ​​the field H11 stored in the server 100. Here, it is assumed that the aperture setting of the spray nozzle of the fertilizer applicator 30 that sprays material A in the field H11 has been calculated to be 20%. The fertilization proposal calculation unit 116 includes this aperture setting (20%) in the fertilization proposal FP.

[0099] The first communication device 130 transmits a fertilization proposal FP for the field H11 (including control information for an aperture setting of 20%) to the fertilizer applicator 30. The fertilizer applicator 30 spreads the material A in the field H11 with the aperture setting of the spray nozzle set to 20%. As a result, the material A is spread in the field H11 at a fertilizer application rate of "15.0 kg / 10 a" per tan.

[0100] For the field H12, the fertilization proposal calculation unit 116 calculates a fertilization proposal FP (including control information with an opening setting of 27%) for the field H12, similar to the field H11. The fertilizer applicator 30 spreads the material A in the field H12 with the spray nozzle opening set to 27%. As a result, the material A is spread in the field H12 at a fertilizer application rate of "20.0 kg / 10 a". For the field H13, the fertilization proposal calculation unit 116 calculates a fertilization proposal FP (including control information with an opening setting of 40%) for the field H13, similar to the field H11. The fertilizer applicator 30 spreads the material A in the field H13 with the spray nozzle opening set to 40%. As a result, in field H13, material A will be spread at a fertilizer application rate of 30.0 kg / 10a per tan.

[0101] As described above, according to the agriculture support system 1, as shown in FIG. 16, it is possible to easily execute inter-field variable fertilization in which the amount of fertilizer applied varies for each field.

[0102] 16 is based on one material (only material A), but there may be cases where multiple materials are used (for example, two materials, material A and material B). For example, when low cost priority is selected, the fertilization proposal calculation unit 116 calculates a fertilization proposal that includes multiple materials (for example, two materials, material A and material B). In this case, based on the fertilization proposal FP, the fertilization proposal calculation unit 116 identifies the materials to be fertilized in field H11 as "material A" and "material B" and the fertilizer amounts (e.g., fertilizer amount per tan) of material A and material B as "15.0 kg / 10a" and "7.0 kg / 10a", and calculates, for the area of ​​field H11 stored in the server 100, the aperture setting of the spray nozzle of the first fertilizer applicator 30A that satisfies the fertilizer amount per tan for "material A", and the aperture setting of the spray nozzle of the second fertilizer applicator 30B that satisfies the fertilizer amount per tan for "material B".

[0103] Here, it is assumed that the aperture setting of the spray nozzle of the first fertilizer applicator 30A that sprays material A in the field H11 is calculated to be 20%, and the aperture setting of the spray nozzle of the second fertilizer applicator 30B that sprays material B in the field H11 is calculated to be 10%. The fertilization proposal calculation unit 116 includes the aperture setting of the first fertilizer applicator 30A (20%) and the aperture setting of the second fertilizer applicator 30B (10%) in the fertilization proposal FP.

[0104] The work vehicle 20 (e.g., a tractor) can simultaneously mount the first fertilizer applicator 30A and the second fertilizer applicator 30B side-by-side at the rear, and materials can be spread simultaneously by the first fertilizer applicator 30A and the second fertilizer applicator 30B. The work vehicle 20 may also be capable of mounting the first fertilizer applicator 30A at the front and the second fertilizer applicator 30B at the rear.

[0105] The server 100 also includes a calibration map calculation unit 117. The calibration map calculation unit 117 calculates a calibration map that complements the distribution of the remaining component values, using a distribution map DM that indicates the distribution of some of the soil component values ​​in the field, and the soil analysis result RT acquired from the soil analyzing device 90. The above-mentioned processor executes a calculation program for calculating the calibration map stored in the storage device 120, thereby functioning as the calibration map calculation unit 117.

[0106] The distribution map DM shown in Fig. 17 is created as follows. A work vehicle 20 (e.g., a tractor) has a storage device 21 and a positioning device 22 capable of detecting its own position based on a positioning signal from, for example, a GPS satellite, and travels in a field with a soil sensing implement attached. The storage device 21 of the work vehicle 20 stores a series of data that associates each position of the vehicle with some of the soil component values ​​(e.g., EC or pH, etc.) measured by the soil sensing implement. The series of data stored in the storage device 21 of the work vehicle 20 is transmitted to the server 100. The control device 110 of the server 100 generates a distribution map DM showing the distribution of some of the component values ​​(e.g., EC or pH, etc.) in the field based on the series of data.

[0107] The calibration map calculation unit 117 calculates a calibration map that complements the distribution of the remaining component values, using the distribution map DM and the soil analysis result RT obtained by analyzing the soil in the field with the simple soil sensor (or the soil analysis result RT obtained from the analysis device). For example, a calibration map is created that reflects (complements) the distribution of soil component values ​​other than EC and pH to the distribution map DM that shows the distribution of EC or pH.

[0108] The fertilization proposal calculation unit 116 calculates a variable fertilization map VM that sets the fertilization amount indicated by the fertilization proposal FP for each of a plurality of areas obtained by dividing the calibration map into a grid shape according to the soil component values ​​of the corresponding areas and has position information for each area. In other words, the variable fertilization map VM is calculated for performing variable fertilization so that the soil component values ​​(nitrogen, phosphorus, potassium, lime, magnesia, pH, lime / magnesia, magnesia / potassium, etc. shown in FIG. 17) of the plurality of areas fall within predicted values. The first communication device 130 transmits the variable fertilization map VM to the fertilizer applicator 30.

[0109] The control device 110 may include a soil improvement proposal calculation unit 114, a creation unit 115, and a fertilization proposal calculation unit .

[0110] The main characteristic features and effects of the agriculture support system 1 in the embodiment described above are as follows.

[0111] (Item A1) Field information, crop information, and analysis data of soil collected by the soil analyzer 90 An acquisition unit 111 that acquires soil analysis information of the field, including A control device 110 that specifies a fertilization standard for the field based on the soil analysis information obtained. 1. Agricultural support system in place.

[0112] According to this configuration, it is possible to identify a fertilization standard suitable for a field, and to provide the fertilization standard suitable for the field to a user. Therefore, the user can improve agricultural work in the field by using the fertilization standard suitable for the field.

[0113] (Item A2) The agricultural support system 1 described in Item A1 is provided with a memory device 120 that pre-stores multiple fertilization standards corresponding to crops for each region, and the control device 110 identifies a fertilization standard that corresponds to the contents of the soil analysis information from the multiple fertilization standards stored in the memory device 120.

[0114] According to this configuration, the fertilization standard for the field that corresponds to the contents of the soil analysis information is identified from among multiple fertilization standards stored in the memory device 120, so that the user can be provided with the fertilization standard for the field that matches the soil analysis information of the field.

[0115] (Item A3) The plurality of fertilization standards include one or more areas in a map and the soil type of the areas; The fertilization standard is associated with each combination of the crop information, and the soil type and the crop information are weighted and stored in the storage device 120; The soil analysis information includes location information of the field, soil type of the field, and crop information. The control device 110 selects the content of the soil analysis information and the fertilization standard from the plurality of fertilization standards. The agricultural support system according to item A2, which identifies the fertilization standard with the highest total score that matches 1.
