Description

System and method for providing cultivation schedules for field crops that can be updated according to changes in cultivation environment

[0001] The present invention relates to a system and method for providing a cultivation schedule for field crops, which plans and provides the entire cultivation schedule from the first step of cultivating field crops, which is making cultivation soil, to the last step, which is harvesting, in accordance with the characteristics of the crop and the cultivation environment, and during the cultivation period, the established cultivation schedule is updated and provided in accordance with changes in the cultivation environment, and which enables the schedule to be updated in accordance with changes in the cultivation environment.

[0002] Field crops are crops grown under natural conditions in cultivated fields.

[0003] Recently, smart farm technology is expanding, with sensor networks, environmental control devices, and other technologies collecting information on temperature, humidity, and soil conditions in cultivation facilities and providing an appropriate environment for cultivation and cultivation.

[0004] However, smart farm technology is focused on facility cultivation, such as facility horticulture and plant factories, and there is a relative lack of smart technology for open-field cultivation.

[0005] Therefore, users who wanted to cultivate fields had to decide on crop varieties and cultivation scale based on their previous cultivation management experience and know-how. They then purchased agricultural supplies based on these determined crop varieties and scale. In other words, users had no choice but to plan and manage their own cultivation schedule.

[0006] However, the existing method has the disadvantage of having a high failure rate in cultivation because it relies solely on subjective judgment based on the user's experience and know-how, and in the case of growers who do not have extensive experience in crop cultivation, they are bound to have difficulties in cultivation work.

[0007] Accordingly, smart farm technology is required to provide an appropriate environment for cultivation and cultivation of each crop, even for field crops.

[0008] Moreover, with climate change intensifying due to global warming and other factors, and with rising temperatures adjusting the appropriate growing period and changing the types of crops suitable for that temperature, there is an even greater need for a cultivation management schedule that reflects the predicted climate.

[0009] The present invention is intended to solve the above problems, and the technical task of the present invention is to provide a system and method for providing a cultivation schedule for field crops, which automatically plans and provides the entire cultivation schedule from the first step of cultivating field crops, which is making cultivation soil, to the last step, which is harvesting, in accordance with the characteristics of the crops and the cultivation environment.

[0010] In addition, another technical task of the present invention is to provide a smart system that can adaptively manage cultivation even in response to environmental changes by automatically readjusting and updating the cultivation schedule according to changes in the cultivation environment during the cultivation period, as field crops can be greatly affected by external environmental factors as they are cultivated under natural environmental conditions.

[0011] In addition, another technical task of the present invention is to provide not only the timing of fertilizer application required for the growth process of each crop but also the timing and method of prescribing crop protection agents (pesticides) that can cope with environmental changes when initially establishing a cultivation schedule or when readjusting the cultivation schedule according to changes in the cultivation environment, thereby enabling easy cultivation even by growers without specialized knowledge of crops.

[0012] Meanwhile, the technical tasks to be achieved in the present invention are not limited to the technical tasks mentioned above, and other technical tasks not mentioned can be clearly understood by a person having ordinary knowledge in the technical field to which the present invention belongs from the description below.

[0013] In order to solve the above technical problem, a method for providing a cultivation schedule for an open-field crop according to an embodiment of the present invention is a method for providing a cultivation schedule for an open-field crop online, comprising: a step in which a server receives a variety of a crop and a cultivation site address from a grower terminal and requests a cultivation schedule plan; a step in which the server searches for and acquires crop information from a crop DB with respect to the variety of the crop input from the grower terminal; a step in which the server searches for and acquires regional climate information corresponding to the cultivation site address input from the grower terminal from a climate DB; and a step in which the server establishes a cultivation schedule including the entire cultivation period from the first cultivation step, which is making cultivation soil, to the last cultivation step, which is harvesting, based on the crop information for each crop and the climate information according to the cultivation site region.

[0014] The step of establishing the above cultivation schedule includes a step in which the server obtains the necessary accumulated temperature, the optimal growth temperature, the growth limit temperature (including the highest limit temperature and the lowest limit temperature), and the growth hazard temperature (including the high temperature hazard temperature and the low temperature hazard temperature) from the crop information for each crop, a step in which the server collects predicted climate information according to the cultivation area for a certain period of time and calculates the periods in which the necessary accumulated temperature for each crop is determined based on the collected predicted climate, a step in which the server excludes the period including the crop-specific growth hazard temperature (the high temperature hazard temperature and the low temperature hazard temperature) from the calculated periods, a step in which the server selects the period including the most days with the crop-specific optimal growth temperature from the remaining periods, and a step in which the server calculates the selected period as the optimal cultivation period and allocates the main work period necessary for the crop during the calculated cultivation period to establish the main cultivation schedule.

[0015] At this time, the step of calculating the periods that become the necessary accumulated temperature for each crop based on the collected predicted climate is to calculate the periods in which the sum of the temperatures on days when the average daily temperature is higher than the critical temperature in the collected predicted climate matches the necessary accumulated temperature for each crop, and the critical temperature is 0℃ when the sum of the accumulated temperatures for each crop is applied, and becomes the lowest limit temperature of the growth limit temperature when the sum of the effective accumulated temperatures for each crop is applied.

[0016] In addition, after the step of establishing a main cultivation schedule by assigning a main work period required for the crop, the server searches for and acquires soil information by region corresponding to the cultivation site address input from the grower terminal from the soil DB, detects the nutrient retention status of the soil by cultivation site region from the acquired soil information, and the server searches for and acquires nutrient information required for each growth stage of the crop according to the variety of the crop input from the grower terminal from the crop DB, and then, based on the nutrient retention status of the soil by region, the nutrient information required for each growth stage of the crop, and the main cultivation schedule, the type, fertilization period, and fertilization amount of fertilizer required for the growth of the crop can be calculated and added to a detailed cultivation schedule.

[0017] When the server calculates the type of fertilizer, it searches for and obtains a fertilizer having a nutrient component expected to be insufficient for the growth of the crop according to the nutrient retention status of the soil in each region from the fertilizer DB, and if there are multiple nutrients expected to be insufficient for the growth of the crop and a fertilizer containing all of the multiple nutrients is not searched, it can present a plurality of types and mixing ratios of fertilizers by combining fertilizers having at least one nutrient component among the multiple nutrients.

[0018] In addition, after the step of establishing a major cultivation schedule by assigning major work periods required for the crops, the server can predict the impact on crops according to climate conditions or climate environment changes based on predicted climate information during the cultivation period for which the major cultivation schedule is established, and calculate the type of crop protection agent (pesticide), crop protection agent prescription period, and supply amount based on the predicted results, and add them to the detailed cultivation schedule.

[0019] In addition, after the step of establishing the cultivation schedule, the method further includes: a step in which the server receives a request for a change to the cultivation schedule; a step in which the server searches for and acquires climate information newly updated from the requested current time from the climate DB; and a step in which the server readjusts the cultivation schedule based on the crop information for each crop and the newly updated climate information, excluding major tasks that have already been performed and including major task periods that have not been performed.

[0020] At this time, the step of requesting a change to the cultivation schedule may be performed by adjusting the unimplemented schedule to the actual implementation date and then receiving an update request from the cultivator terminal, if the cultivation schedule needs to be changed because the cultivation schedule has not been implemented.

[0021] In addition, the step of requesting a change in the cultivation schedule may include a step of the server monitoring regional climate information corresponding to the cultivation site address newly updated in the climate DB, a step of the server providing a notification message notifying that a change in the cultivation schedule is necessary when the monitoring result indicates that a rapid climate change has occurred or abnormal weather has continued and damage to the crops is expected, and a step of receiving a request for updating the main cultivation schedule in response to the notification message.

[0022] In addition, in the step of readjusting the cultivation schedule based on the newly updated climate information, the server updates the climate information from the past to the present time, which is already past the cultivation period, with actual climate information, and updates the climate information after the present time with the newly updated predicted climate information.

[0023] In addition, the step of readjusting the cultivation schedule based on the newly updated climate information may include a step in which the server obtains the necessary accumulated temperature, the optimal growth temperature, the growth limit temperature (including the highest limit temperature and the lowest limit temperature), and the growth hazard temperature (including the high temperature hazard temperature and the low temperature hazard temperature) from the crop information for each crop, a step in which the server collects newly updated climate information after a current point in time and calculates a period for the necessary accumulated temperature for each crop using the current point in time as the starting point of the cultivation schedule, and a step in which the server readjusts by allocating a major work period necessary for the crop to the calculated period, excluding major work periods that have already been performed and including major work periods that have not been performed.

[0024] The above required accumulated temperature for each crop is information obtained by adding up the actual temperatures required from planting to harvest, and the required accumulated temperature at the current point in the growing period is the temperature obtained by subtracting the actual accumulated temperature obtained by adding up the actual temperatures from the past, which is the time since planting the crop, to the current point in time from the required accumulated temperature for each crop.

[0025] After the step of readjusting the above cultivation schedule, the server may further include a step of calculating the type and amount of fertilizer required for crop growth based on the newly updated climate information, calculating the fertilization period based on the readjusted cultivation schedule, and adding or changing the detailed cultivation schedule.

[0026] After the step of readjusting the above cultivation schedule, the server may further include a step of predicting the impact on crops based on the newly updated climate information, calculating the type and supply amount of crop protection agents (pesticides) based on the predicted result, and calculating the prescription time based on the readjusted main cultivation schedule to change or add to the detailed cultivation schedule.

[0027] In addition, in a method according to an embodiment of the present invention, when the cultivation schedule for each crop is completed and harvested through the steps of establishing the cultivation schedule and the steps of readjusting the cultivation schedule, the server can recalculate the actual accumulated temperature required by the crop based on the actual cultivation period for each crop for which the cultivation schedule has been completed and the actual climate information during the actual cultivation period, and update the recalculated actual accumulated temperature in the crop DB.

[0028] Meanwhile, a system for providing a cultivation schedule for field crops according to an embodiment of the present invention is a system for managing a cultivation schedule for field crops online, and includes a database including a crop DB, a climate DB, a soil DB, a fertilizer DB, and a crop protection agent DB in which various data necessary for cultivating the field crops are stored; and a cultivation schedule establishment module that, when a crop variety and a cultivation site address are input from a cultivator terminal and a cultivation schedule plan is requested, searches and acquires crop information on the crop variety from the crop DB, and at the same time, searches and acquires regional climate information corresponding to the cultivation site address input from the cultivator terminal from the climate DB, and establishes a cultivation schedule including the entire cultivation period from the first cultivation step, which is making cultivation soil, to the last cultivation step, which is harvesting, based on the acquired crop information for each crop and the climate information according to the cultivation site region.

[0029] In addition, when a request is made to change a cultivation schedule established through the cultivation schedule establishment module, a cultivation schedule automatic adjustment module may be further included, which searches for and acquires newly updated climate information from the climate DB as of the requested current time point, and readjusts the cultivation schedule based on the crop information for each crop and the newly updated climate information, but readjusts by excluding major tasks that have already been performed and including major task periods that have not been performed.

[0030] According to this embodiment of the present invention, by simply inputting the variety of crops to be grown and the address of the cultivation site, the entire cultivation schedule from the first stage of cultivation, making cultivation soil, to the last stage, harvesting, is automatically established and provided, thereby enabling cultivation management even by a cultivator without experience or knowledge in crop cultivation.

[0031] Moreover, it automatically informs of detailed cultivation schedules such as fertilizer management, pest control, and weed control required for each crop's growth process, enabling efficient management of complex cultivation schedules.

[0032] Furthermore, according to an embodiment of the present invention, by accurately calculating and providing the amount of fertilizer application and crop protection agent supply based on the characteristics of the field crop (based on crop information), cultivation scale, soil environment (based on soil information), and climate environment (based on climate information), it is possible to quantitatively calculate the amount even if production increases or decreases, enabling precision farming and maximizing production. Furthermore, environmental pollution can be minimized by using only the necessary amount.

[0033] In particular, according to an embodiment of the present invention, in the case of field crops with a long cultivation period, an optimized cultivation schedule is provided based on predicted climate information, and if the predicted and actual climate during the cultivation period differ or the schedule is not carried out according to the cultivation schedule, the optimal cultivation schedule is updated again at the current point in time, thereby enabling adaptive cultivation management in response to environmental changes. This provides the effect of reducing trial and error and increasing productivity.

[0040] Figure 7 is an exemplary diagram showing an input / output screen of a system according to an embodiment of the present invention.

[0041] Hereinafter, embodiments of the present invention will be described with reference to the attached drawings. In describing with reference to the attached drawings, identical or corresponding components are assigned the same drawing numbers, and redundant descriptions thereof will be omitted.

[0042] Figure 1 is a diagram showing the overall configuration of a system for providing a field crop cultivation management schedule according to an embodiment of the present invention.

[0043] As illustrated, the system for providing a cultivation schedule for field crops according to an embodiment of the present invention includes a cultivation schedule providing server (hereinafter referred to as “server”) that plans and manages a cultivation schedule for field crops online, and a database (500) in which various types of information necessary for crop cultivation are stored.

[0044] In addition, the server includes a cultivation schedule establishment module (100), a cultivation schedule adjustment module (200), a climate environment monitoring module (300), a crop protection agent prescription module (400), and a fertilizer prescription module (500).

[0045] In Figure 1, the configuration of the server is functionally divided and illustrated, but it is not limited thereto, and two or more modules may be implemented in an integrated manner as needed.

[0046] In this embodiment, the server can be connected to any portal site to provide a cultivation schedule service via the web or web browser. Alternatively, if the server is implemented as a single application and installed on a terminal, both cultivation schedule requests and cultivation schedule management can be performed through a single terminal.

[0047] The database (700), also called a storage server, collects various information about crops and stores various data necessary for planning and managing cultivation schedules. Specifically, the database (700) may include a crop database, a soil database, a climate database, a fertilizer database, a crop protection agent database, a schedule storage database, and the like.

[0048] The crop DB stores various information about crops, such as the required accumulated temperature for each crop variety, optimum germination temperature, optimum growth temperature, growth limit temperature (highest limit temperature, lowest limit temperature), growth tolerance temperature (high temperature tolerance temperature, low temperature tolerance temperature), number of growing days, average growing period, optimum growing environment conditions, issues that may arise due to weather changes, countermeasure information, and nutrients or nutritional supplements necessary for crop growth.

[0049] The required accumulated temperature (REC) is an indicator of the amount of heat required for crop growth from sprouting to harvest, and varies depending on the crop's growing season and period. For example, the required accumulated temperature (REC) of buckwheat is approximately 1000°C to 1200°C, making it the crop with the lowest REC, while that of rice is approximately 3500°C to 4500°C, making it the crop with the highest REC.

[0050] Depending on the crop, the required accumulated temperature can be expressed as the sum of the accumulated temperature or the effective accumulated temperature.

[0051] The accumulated temperature is the sum of the daily average temperatures above 0℃ from the sprouting of the crop to the harvest (a certain period), and the effective accumulated temperature is the sum of the daily average temperatures from the sprouting of the crop to the harvest (a certain period) minus the minimum critical temperature. Usually, the minimum critical temperature is applied based on 10℃ for summer crops and 5℃ for winter crops and fruit trees, and a preset minimum critical temperature may be applied depending on the crop. The minimum critical temperature for potato crops is 5℃, and the minimum critical temperature for rice crops is 8℃.

[0052] Among the growth limit temperatures, the highest limit temperature is the highest temperature at which crops can grow, and the lowest limit temperature is the lowest temperature at which crops can grow.

[0053] Growth hazard temperature is the temperature at which low temperature damage and high temperature damage can occur. Low temperature damage refers to physiological damage caused by low temperature, which reduces the water and nutrient absorption function of crops, resulting in various related damages. High temperature damage refers to physiological damage caused by high temperature, which increases consumption of organic matter, causes abnormalities in nitrogen metabolism, causes chlorosis due to chlorophyll formation disorder caused by iron precipitation, or causes plants to wither due to excessive transpiration. In the case of potato crops, the growth hazard temperature at which low temperature damage occurs can be 5 degrees, which is the minimum limit temperature, 3 degrees when frost occurs, and 0 degrees when freeze damage occurs. The growth hazard temperature at which high temperature damage occurs can be 30 degrees.

[0054] The optimum temperature for growth is the temperature range where crops grow best, also called the 'optimal temperature for growth', and is usually included within the range of the minimum and maximum temperature limits.

[0055] The soil database is linked to regional information, storing soil information specific to the address of the cultivated field. Because soil characteristics vary by region and environment, information such as the nutrient content of each soil and soil suitability for each crop (information on which crops thrive based on soil properties) is stored.

[0056] The soil database can be based on soil information measured by growers, or service providers can build a new database by collecting soil information for each region. Furthermore, it can be linked to the soil database currently being used by the Rural Development Administration.

[0057] The climate database stores regional climate information. The climate database can be applied by linking it to climate databases provided by the Korea Meteorological Administration or specific portals.

[0058] Regional climate information includes regional past climate information (past temperature information from one year prior to the current point in time) and the Korea Meteorological Administration's predicted climate information (short-term forecast, medium-term forecast, one-month outlook, three-month outlook, and annual outlook).

[0059] The fertilizer DB and crop protection agent DB store information on fertilizers (including crop nutrients) and crop protection agents required for the growth process of each crop, categorized into organic and general agricultural materials.

[0060] When the cultivation schedule establishment module (100) receives input of the crop variety and cultivation site address from the cultivator terminal and requests a cultivation schedule plan, it searches and acquires crop information for each crop and climate information for each cultivation site area from the data stored in the crop DB and climate DB of the database (700), and establishes a cultivation schedule including the entire cultivation period from the first cultivation step, making cultivation soil, to the last step, harvesting, based on the acquired data.

[0061] At this time, the cultivation schedule establishment module (100) suggests an optimal cultivation schedule, and when the schedule for major cultivation schedules such as crop planting and harvesting is changed, the entire schedule is changed, and the change in schedule can be selected within the possible cultivation schedule.

[0062] Additionally, the cultivation schedule establishment module (100) can present one or more cultivation periods. For example, for a crop with a three-month growing period, a cultivation period from March to June, which is the current period, and a cultivation period from June to September can be presented.

[0063] The cultivation schedule is divided into a main cultivation schedule and a detailed cultivation schedule. The main cultivation schedule includes the first stage of cultivation, which is preparing the cultivation soil, planting the crops (sowing or transplanting), and the final stage, harvesting. If preparing the cultivation soil is not necessary, it can be included after the planting stage. The detailed cultivation schedule may include schedules for fertilizer application, crop protection agent prescription, specific tasks such as drainage management, and crop nutrient prescription to supplement photosynthesis.

[0064] The cultivation schedule establishment module (100) establishes a main cultivation schedule, and then calculates the type, fertilization period, and amount of fertilizer based on the regional soil information corresponding to the cultivation site address input from the grower terminal, and can add the calculated fertilization period to the detailed cultivation schedule.

[0065] In addition, the cultivation schedule establishment module (100) establishes a main cultivation schedule, and then calculates the type, crop protection agent (pesticide) prescription time, and supply amount by considering the impact on crops according to climate conditions or climate change based on predicted climate information during the cultivation period, and can add the calculated prescription time to the detailed cultivation schedule.

[0066] In this way, as shown in FIG. 2, when a crop to be grown is input, the cultivation schedule establishment module (100) automatically plans and provides a major cultivation schedule according to the characteristics of the crop (crop information) and the cultivation environment (climate information), and can provide a detailed cultivation schedule including fertilizer application and crop protection agent prescription in the cultivation period to supply nutrients necessary for the growth of the crop.

[0067] Here, the fertilizer application schedule can be determined in conjunction with the fertilizer prescription module (500). That is, when a prescription of fertilizer is required for each crop's growth process, as shown in the process in Fig. 3, the cultivation schedule establishment module (100) can work in conjunction with the fertilizer prescription module (600) to calculate the type of fertilizer, amount of fertilizer, and fertilizer schedule required according to the crop variety and growth period, and include them in the cultivation schedule.

[0068] The prescription schedule of crop protection agents can be determined in conjunction with the crop protection agent prescription module (400). That is, when pests or physiological disorders are expected during the cultivation period, the crop protection agent prescription module (400) calculates the type, supply amount, and prescription time of the necessary crop protection agent according to the crop variety, growing season, and expected climate, and the cultivation schedule establishment module (100) can include the information calculated by the crop protection agent prescription module (400) in the cultivation schedule.

[0069] In Fig. 2, a specific method for calculating a cultivation schedule using the required accumulated temperature for each crop in the process of establishing a cultivation schedule (P100) and the process of adjusting the cultivation schedule (P200) is described in Figs. 5 and 6 below.

[0070] Referring again to FIG. 1, the cultivation schedule adjustment module (200) readjusts the cultivation schedule established through the cultivation schedule establishment module (100) according to whether the cultivation schedule is being followed and climate change, thereby creating cultivation conditions that are optimal for the growth of crops.

[0071] Specifically, the cultivation schedule adjustment module (200) receives a request for a change in the cultivation schedule from a grower or the system after establishing the cultivation schedule through the cultivation schedule establishment module (100). In response, the cultivation schedule adjustment module (200) searches for and obtains newly updated climate information from the climate DB as of the current time point when the update request is received, and readjusts the cultivation schedule based on the crop information for each crop and the newly updated climate information. At this time, the cultivation schedule adjustment module (200) can readjust the cultivation schedule by excluding major tasks that have already been performed and including the period of major tasks that have not been performed.

[0072] A request for a change in the cultivation schedule may be made, for example, when a grower fails to fulfill a portion of the main cultivation schedule established through the cultivation schedule establishment module (100), necessitating a change in the cultivation schedule. In this case, the grower adjusts the unfulfilled schedule to the actual implementation date, then directly requests an update using the grower's terminal, and the cultivation schedule adjustment module (200) receives the grower's update request from the grower's terminal.

[0073] As another example, a request for a change in the cultivation schedule may be made by an alarm for abnormal weather symptoms through monitoring by the climate environment monitoring module (300). That is, the climate environment monitoring module (300) monitors regional climate information corresponding to the cultivation site address, which is newly updated in the climate DB, and if the monitoring results indicate that a rapid climate change occurs or abnormal weather persists, which may cause crop damage, a notification message is provided notifying that a change in the cultivation schedule is necessary. This can be provided by displaying it on the screen of a system connected to the climate environment monitoring module (300) or transmitting it to the grower terminal to directly notify the grower. Then, in response to the notification message, the cultivation schedule adjustment module (200) receives an update request from the climate environment monitoring module (300) or the grower terminal, thereby making a request for a change in the cultivation schedule.

[0074] The cultivation schedule adjustment module (200) that receives the update request in this way updates the climate information updated in the climate DB. It updates the climate information from the past to the present time, which is already past time in the cultivation period, with actual climate information, and updates the climate information after the present time with newly updated predicted climate information.

[0075] Only after the update process, the cultivation schedule adjustment module (200) readjusts the cultivation schedule based on the updated climate information and the required accumulated temperature for each crop. At this time, the current point in time is set as the starting point of the cultivation schedule, and the cultivation schedule is readjusted to include the main work periods that have not been performed, excluding the main work periods that have already been performed.

[0076] In addition, the cultivation schedule adjustment module (200) can readjust, add, delete, or change the fertilizer application schedule and the crop protection agent prescription schedule, or the fertilizer application amount / supply amount, based on the readjusted cultivation schedule. In this case as well, the cultivation schedule adjustment module (200) determines the fertilizer application schedule, the crop protection agent prescription schedule, etc. in conjunction with the fertilizer prescription module (500) and the crop protection agent prescription module (400), and the cultivation schedule adjustment module (200) receives the information determined by the fertilizer prescription module (500) and the crop protection agent prescription module (400) and includes it in the cultivation schedule.

[0077] Then, referring to the above system configuration, a method for automatically establishing and readjusting the cultivation schedule of field crops and a method for calculating the cultivation period based on the required accumulated temperature for each crop during establishment and readjustment are specifically explained.

[0078] Figure 4 is an overall flowchart showing a method for providing an open-field crop cultivation schedule in a system according to an embodiment of the present invention.

[0079] A system according to an embodiment of the present invention includes a server and a database, and the database is a storage medium that provides data necessary for automatically planning and readjusting a cultivation schedule in the server, so the server performs the main function.

[0080] The method by which a server provides a cultivation schedule for field crops online is largely composed of a cultivation schedule establishment step (S100) and a cultivation schedule adjustment step (S200).

[0081] The cultivation schedule establishment step (S100) will be performed through the cultivation schedule establishment module (100) of the server, and the cultivation schedule adjustment step (S200) will be functionally performed through the cultivation schedule adjustment module (200) of the server.

[0082] First, in the cultivation schedule establishment step (S100), the grower terminal requests a cultivation schedule plan for the crop to be cultivated (S110), and the server receives the variety of the crop to be cultivated and the cultivation site address from the grower terminal in the cultivation schedule establishment module, and at the same time, requests a cultivation schedule plan (S120).

[0083] Here, crop variety and cultivation site address are required inputs. Additional information can be entered, including whether the cultivation is eco-friendly, whether it's early, cultivation season, and soil testing data. Furthermore, in addition to the cultivation site address, growers can be requested to input information such as the cultivation site area (scale) and soil information. Figure 7 shows an example of a cultivation information input screen.

[0084] Next, the server searches for and obtains various data necessary for cultivation based on the crop variety and cultivation site address input from the grower terminal (S130).

[0085] Specifically, the server retrieves and obtains crop information from the crop DB for the crop variety input from the grower terminal.

[0086] Additionally, the server searches for and obtains climate information by station from the climate DB to determine whether it corresponds to the cultivation site address entered by the grower terminal.

[0087] Next, the server establishes a cultivation schedule that includes the entire cultivation period from the first cultivation step, making cultivation soil, to the last step, harvesting, based on crop information for each crop and climate information for each cultivation area (S140).

[0088] In the process of establishing the above cultivation schedule (S140), the main cultivation schedule is planned by assigning the main work periods required for the crop. For example, the main cultivation schedule basically includes the schedule for preparing the cultivation soil (cultivation, mulching), planting the crop (sowing, transplanting), and harvesting. The cultivation schedule output screen of Fig. 7 includes the main cultivation schedule required for the crop, such as cultivation and mulching on March 12, 2023, sowing on March 15, 2023, transplanting on April 1, 2023, and harvesting on July 15, 2023.

[0089] As shown in the example screen of Figure 7, when a grower inputs 'Crop: Potato / Variety: Sumi' as the crop variety and 'Danwol-dong, Chungju-si, Chungcheongbuk-do' as the cultivation site address, the server automatically plans a cultivation schedule including the optimal cultivation period and main work period by considering the characteristics of the crop and the cultivation environment of Chungju-si, Chungcheongbuk-do, and provides it as shown in the cultivation schedule output screen on the right.

[0090] In the cultivation schedule output screen, the method for calculating the cultivation period from 2023.02.28 to 2023.07.15 is as shown in Figs. 5 and 6.

[0091] The server obtains the required accumulated temperature, growth limit temperature (including the highest limit temperature and the lowest limit temperature), and growth hazard temperature (including the high temperature hazard temperature and the low temperature hazard temperature) from crop information for each crop to calculate the cultivation period, and collects climate information according to the cultivation area for a certain period (S141).

[0092] Next, the server calculates the periods in which the required accumulated temperature for each crop is filled based on the climate information collected over a certain period of time (S142).

[0093] The period of time here may change depending on the service policy, but can generally be considered as the period of the past year and the period of predicted climate information provided by the Korea Meteorological Administration.

[0094] In addition, specifically, the calculation method uses a method of calculating the periods in which the sum of the temperatures in the collected climate where the average daily temperature is higher than the critical temperature matches the required accumulated temperature for each crop. At this time, the critical temperature is 0℃ when the method of adding the accumulated temperature is applied, and it becomes the minimum temperature of the growth limit temperature for each crop when the method of adding the effective accumulated temperature is applied. In the former case, the periods in which the accumulated temperature, which is the sum of the temperatures on days when the average daily temperature is higher than 0℃, matches the stored required accumulated temperature for each crop are calculated. In the latter case, the periods in which the effective accumulated temperature, which is the sum of the temperatures on days when the average daily temperature is higher than the minimum critical temperature for the crop, matches the stored required effective accumulated temperature for each crop are calculated.

[0095] For example, the graph in Fig. 6 shows predicted climate information for a cultivation area for approximately one year from January 8, 2023, to December 10, 2023. The light-colored graph represents the maximum daily temperature in the predicted climate from January 8, 2023, to December 10, 2023, the medium-shaded graph represents the average daily temperature in the predicted climate from January 8, 2023, to December 10, 2023, and the dark-colored graph represents the minimum daily temperature in the predicted climate from January 8, 2023, to December 10, 2023. This predicted climate information can be obtained from a climate database.

[0096] In the case of field crops such as potatoes, the minimum required accumulated temperature is 1,000℃, the maximum temperature is 25℃, the minimum temperature is 5℃, and the low temperature hazard temperature for growth is known to be 5℃ or lower, the high temperature hazard temperature is 30℃ or higher, and the optimal growth temperature is known to be 14℃ to 23℃.

[0097] Potatoes, too, have over 40 registered varieties, which can be categorized into early-maturing, mid-maturing, and late-maturing varieties based on their ripening period. Early-maturing varieties typically have a growing period of 80 to 95 days, mid-maturing varieties 95 to 110 days, and those over 110 days are classified as late-maturing varieties.

[0098] The most planted potato variety in Korea for the past 50 years has been 'Sumi' imported from the United States, but recently it has shown vulnerability to high temperatures and heavy rains due to global warming, and its yield has decreased. Therefore, varieties that have adapted to high temperatures and have higher yields or better shapes, textures, and tastes are being developed one after another. Depending on the variety, the growing period, or required accumulated temperature (or required effective accumulated temperature), is all different.

[0099] For a specific variety of potato crop whose cultivation schedule has already been completed and harvested, the required accumulated temperature or required effective accumulated temperature for that specific variety can be measured by applying temperature information during the actual cultivation period from planting to harvest. By tracking the planting and harvest times for a specific variety based on the actually measured required accumulated temperature or required effective accumulated temperature, the precise cultivation period can be obtained conversely.

[0100] For example, in the case of potato crop of variety A, if the accumulated temperature, which is the sum of the temperatures on days when the average daily temperature is 0℃ or higher during the growing period, is 1300℃, then the required accumulated temperature, which is the temperature that the crop requires during the growing period, is 1300℃, and therefore, from the predicted climate information, the periods in which the sum of the temperatures on days when the average daily temperature is 0℃ or higher matches the required accumulated temperature of 1300℃ for potatoes can be calculated.

[0101] Alternatively, when utilizing the effective accumulated temperature, if the effective accumulated temperature, which is the sum of the temperatures on days when the daily average temperature is 5℃ or higher during the growing period of potato crops of variety A, is 1000℃, then the required effective accumulated temperature, which is the temperature required by the crop during the growing period, is 1000℃, so the periods in which the sum of the temperatures on days when the daily average temperature is 5℃ or higher in the predicted climate information matches the required effective accumulated temperature of 1000℃ for potatoes can be calculated. Here, 5℃ corresponds to the minimum critical temperature for potato crops of variety A, and the temperature sum on days when the daily average temperature is 5℃ or higher refers to the sum of the temperatures obtained by subtracting the minimum critical temperature (5℃) from the daily average temperature on days when the daily average temperature is 5℃ or higher.

[0102] Next, the server excludes the period including the crop growth hazard temperature from the calculated periods (S143).

[0103] The growth retardation temperature refers to the temperature at which low temperature damage and high temperature damage (temperature at which crop growth is impossible) are expected. If the daily average climate falls within the growth retardation temperature, crop stress increases and may die, so if possible, the cultivation schedule within the growth retardation temperature is excluded.

[0104] For example, in the graph of Figure 6, the period including days with a minimum temperature limit of 5℃ or lower, which may cause low-temperature damage, and the period including days with a maximum temperature limit of 27-30℃ or higher, which may cause high-temperature damage, are excluded.

[0105] However, if the minimum or maximum temperature continues for several days, the probability of low-temperature damage or high-temperature damage increases, so this can be adjusted by taking this into account. In the case of crops that are sown or transplanted in the fall, grown throughout the winter, and harvested in the spring (e.g., garlic, onions), the minimum temperature cannot be avoided, so among the growth hazard temperatures, the low-temperature hazard temperature in particular is adjusted.

[0106] Next, the server selects a period that includes the day with the highest optimal growth temperature for each crop among the remaining periods (S144).

[0107] The optimal growth temperature is the optimal temperature range for crop growth, falling within the minimum and maximum critical temperatures. For the potato example mentioned above, the optimal growth temperature is between 14 and 23 degrees Celsius, indicated by the gray box in the graph in Figure 6. The period with the highest number of days with optimal growth temperature is the orange box on the left.

[0108] Next, the server calculates the selected period as the optimal cultivation period and establishes a main cultivation schedule by assigning the main work period required for the crop during the calculated cultivation period.

[0109] Referring again to FIG. 4, after the process of establishing the above cultivation schedule (S140), the server can link the cultivation schedule establishment module and the fertilizer prescription module to determine whether to apply fertilizer and add it as a detailed cultivation schedule to the main cultivation schedule including the main work period.

[0110] Specifically, the server searches for and acquires soil information by region corresponding to the cultivation site address input from the grower terminal from the soil DB, and detects the nutrient retention status of the soil by cultivation site region from the acquired soil information. Then, the server searches for and acquires nutrient information required for each growth stage of the crop according to the crop variety input from the grower terminal from the crop DB. Then, based on the nutrient retention status of the soil by region acquired by the server and the nutrient information required for each growth stage of the crop, the type and amount of fertilizer required for the growth of the crop are calculated, and then the fertilization period is calculated based on the main cultivation schedule selected in step S140 above, and can be added to the detailed cultivation schedule.

[0111] In addition, after the process of establishing the above cultivation schedule (S140), the server can link the cultivation schedule establishment module and the crop protection agent prescription module to determine whether to prescribe a crop protection agent and add it as a detailed cultivation schedule to the main cultivation schedule including the main work period.

[0112] Specifically, the server predicts the impact on crops of climate conditions or environmental changes based on predicted climate information for the growing period for which the main cultivation schedule is established. Based on these predictions, the server calculates the type and supply amount of crop protection agents (pesticides). Furthermore, based on the main cultivation schedule selected in step S140, the server calculates the application timing and adds it to the detailed cultivation schedule.

[0113] At this time, the fertilizer prescription module and crop protection agent prescription module of the server search and obtain fertilizers to supplement nutrients expected to be lacking in current crops based on the nutrient retention status of the soil by region and predicted climate information, or crop protection agents to prevent pests that may appear in current crops based on predicted climate information, from the fertilizer DB and crop protection agent DB. If the corresponding fertilizer is not found, the type and mixing ratio of the mixed fertilizers can be presented by mixing multiple fertilizers.

[0114] For example, Table 1 below shows the soil test results for cultivation area A.

[0115] Unit acidity (PH (1:5)) Organic matter (g / Kg) Available phosphate (mg / Kg) Potassium (cmol+ / Kg) Calcium (cmol+ / Kg) Magnesium (cmol+ / Kg) Electrical conductivity Titration range 6~6.5 25~35 300~400 0.4~0.8 4.0~7.0 1.0~2.0 0.0~2.0 Test result 7.4 15 3800.1 17 1.6 1.1

[0116] The soil of cultivation site A was measured to have an acidity level exceeding the appropriate range (standard) and a potassium content much lower than the appropriate range (standard). Therefore, based on the nutrient retention status of the soil, the amount of organic fertilizer applied was increased to lower the acidity level exceeding the standard, and the potassium content below the standard was increased, while considering the nutrients required by the crop and calculating the composition and amount of fertilizer. An appropriate fertilizer is selected through calculation, but when there is no fertilizer type that exactly matches the required components and fertilizer composition, multiple other fertilizers can be blended to derive the optimized fertilizer mixing ratio.

[0117] Next, the server provides the entire cultivation schedule, including the detailed cultivation schedule and main cultivation schedule produced in the previous steps (S150).

[0118] Next, in the cultivation schedule adjustment step (S200), the server receives a request for a change in the cultivation schedule from the grower or the system through the cultivation schedule adjustment module (S230).

[0119] In response, the server retrieves and obtains newly updated climate information from the climate DB from the time when the update request was received, and readjusts the cultivation schedule based on the crop information for each crop and the newly updated climate information.

[0120] In terms of the method flow, the cultivation schedule request reception (S120), required data retrieval (S130), and cultivation schedule establishment (S130) steps of the cultivation schedule establishment step (S100) are re-performed. However, this is not performed in the cultivation schedule establishment module, and is different from the cultivation period calculation method performed in the cultivation schedule establishment (S130) step.

[0121] That is, in the step of readjusting the cultivation schedule, the server updates the climate information from the past to the present time, which is already past the cultivation period, with actual climate information, and updates the climate information after the present time with newly updated predicted climate information.

[0122] Afterwards, the server obtains the required accumulated temperature, growth limit temperature, and optimal growth temperature from crop information for each crop, and collects newly updated climate information from the current point in time.

[0123] Afterwards, the accumulated temperature from the time of planting the crop to the present time is subtracted from the accumulated temperature required for the overall growth of the crop to calculate the accumulated temperature required for the future growth of the crop, and the new predicted climate information and the accumulated temperature required for the future growth of the crop are calculated to establish a cultivation schedule from the present time onwards.

[0124] Let's explain the field crop of potatoes as an example above. If we assume that the current time when the cultivation date is requested to be updated is 2023.04.05 because the cultivation period is from 2023.02. 28 to 2023.07. 15, the period from 2023.02. 28 to 2023.04. 05, which is when time has already passed, is updated with the actual climate, and from 2023.04. 06, it is updated with the newly updated predicted climate. In addition, if the actual accumulated temperature calculated by adding the actual temperatures from the past to the present during the cultivation period is approximately 100 degrees, the necessary accumulated temperature for each crop applied when readjusting is 900 degrees, which is 100 degrees subtracted from the necessary accumulated temperature of 1000 degrees for potatoes.

[0125] The period for which the potato's required accumulated temperature reaches 900 degrees is calculated by recalculating the starting point from April 5, 2023, when the cultivation schedule was requested for renewal.

[0126] Afterwards, during the period thus calculated, the server reallocates the major work periods required for the crop, excluding major work periods that have already been performed and including major work periods that have not been performed.

[0127] Meanwhile, the process of requesting a change in the cultivation schedule (S230) in the cultivation schedule adjustment step (S200) can be performed, for example, by a cultivation schedule renewal request from the cultivation terminal when a change in the cultivation schedule is necessary due to failure to comply with the main cultivation schedule. The cultivation terminal can access a website linked to the server and make a renewal request, or, if an application linked to the server is installed on the terminal, can make a renewal request within the application.

[0128] As another example, the process (S230) of requesting a change in the cultivation schedule may be performed by an alarm for abnormal climate symptoms through monitoring by the climate environment monitoring module (300). The climate environment monitoring module (300) monitors regional climate information corresponding to the cultivation site address, which is newly updated in the climate DB, and if the monitoring results indicate that a rapid climate change occurs or abnormal climate occurs or persists, and damage to crops is expected, a notification message notifying that a change in the cultivation schedule is necessary may be generated to request an update within the system.

[0129] Next, in the cultivation schedule adjustment step (S200), the server can recalculate whether fertilizer application or crop protection agent prescription is included in the readjusted cultivation schedule and add, delete, or change the amount of fertilizer / supply in the detailed cultivation schedule.

[0130] That is, the server calculates the type and amount of fertilizer required for crop growth based on newly updated climate information, and calculates the fertilization period based on the readjusted main cultivation schedule, thereby changing or adding to the detailed cultivation schedule.

[0131] In addition, if the server determines that prevention is necessary in advance due to the anticipated occurrence of specific pests and diseases depending on the growth stage or climate environment during the crop growth process based on newly updated climate information, it searches the crop protection agent DB and calculates the type, supply amount, and mixing ratio of crop protection agents by considering the size of the cultivation area, and calculates the prescription period based on the readjusted main cultivation schedule, and can change or add detailed cultivation schedules.

[0132] The renewal of the cultivation schedule can change or add to the main cultivation schedule such as making cultivation soil, sowing, transplanting, and harvesting that are already included in the established cultivation schedule, as well as the detailed agricultural work schedule as a response measure to climate change. The detailed agricultural work schedule includes preemptive measures, immediate measures, and post-measures, and can include ecological (agricultural) methods, physical methods, mechanical methods, chemical methods, biological methods, and methods for improving nutritional imbalances.

[0133] Meanwhile, after going through the cultivation schedule establishment stage (S100) and cultivation schedule adjustment stage (S200) described above, the cultivation period can be adaptively adjusted according to regional climate, weather, soil conditions, etc., and crops can be grown according to the adjusted cultivation period.

[0134] Thereafter, the cultivation schedule providing system according to an embodiment of the present invention can accurately know the actual cultivation period and actual climate information during this period for the corresponding crop when the cultivation schedule is completed and harvested through the system, and conversely, by integrating the climate information for the actual cultivation period, the actual accumulated temperature required for cultivating the corresponding crop can be calculated. The actual accumulated temperature calculated in this way becomes actual data acquired for each variety through crop cultivation.

[0135] Accordingly, the cultivation schedule providing system according to an embodiment of the present invention may obtain and apply the necessary accumulated temperature for each variety of crop from the crop DB when calculating the cultivation period of the crop, but may also provide a more accurate cultivation period and cultivation schedule by applying the actual accumulated temperature obtained by completing the actual cultivation period.

[0136] Although the preferred embodiments of the present invention have been illustrated and described above, the present invention is not limited to the specific embodiments described above, and various modifications can be made by those skilled in the art without departing from the gist of the present invention as claimed in the claims. Furthermore, such modifications should not be understood individually from the technical idea or prospect of the present invention.

[0137] The system of the present invention automatically plans and provides a cultivation management schedule required for cultivating a crop based on soil and climate conditions when the cultivator inputs only the crop variety and cultivation site address. In addition, the schedule is readjusted and provided according to climate change even during the cultivation period, thereby enabling adaptive cultivation management to environmental changes. Therefore, the present invention enables easy cultivation management even for cultivators without experience or knowledge in crop cultivation, enables efficient management of complex cultivation schedules, and reduces trial and error to increase productivity, and therefore has high applicability in industries related to crop cultivation.
