[0001] The present invention relates to the technical field of soil detection, and in particular to a soil organic matter rapid detection device and a detection method thereof. Background Art

[0002] Soil organic matter is an important factor in forming soil structure, and plays an important role in improving soil physical and chemical properties and promoting crop nutrient absorption. The content of soil organic matter is one of the important indicators for measuring soil fertility and quality.

[0003] At present, when testing the soil, it is necessary to pre-treat the soil. First, the soil is air-dried, and no moisture can be present inside the soil. After the soil is air-dried, the soil needs to be ground so that the soil particle size reaches the specified standard. Only then can the soil be tested. However, when air-drying and grinding the soil, the existing treatment methods are generally natural air-drying or machine air-drying. When using machine air-drying, a variety of different equipment are needed to air-dry and grind the soil multiple times. If the grinding does not meet the standard, it needs to be reworked, resulting in slow soil testing time and complicated and cumbersome pretreatment operations. Summary of the invention

[0004] In view of the above problems existing in the existing soil organic matter rapid detection device, the present invention is proposed.

[0005] Therefore, the present invention provides a rapid detection device for soil organic matter, the purpose of which is to solve the problem that when using machine air drying, the soil needs to be air-dried and ground multiple times using multiple different equipment, and when the grinding does not meet the standard, it needs to be reworked, resulting in slow soil detection time and complex and cumbersome pretreatment operations.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions: a main unit, comprising a detection device body, a control member arranged on the detection device body, and an unfolding assembly arranged on the top of the detection device body;

[0007] A drying and grinding unit, comprising a drying component arranged inside the unfolding component, a conical guide plate arranged at the bottom of the drying component, and a grinding component arranged at the bottom of the conical guide plate, wherein the conical guide plate and the grinding component are both connected to the unfolding component;

[0008] The detection reaction unit includes a reaction box arranged inside the detection equipment body, a potassium dichromate storage component arranged on one side of the reaction box, a data collection component 2 arranged at the rear end of the potassium dichromate storage component, and a water tank arranged at the other end of the data collection component 2, and the data collection component 2 is electrically connected to the control component.

[0009] As a preferred solution of the soil organic matter rapid detection device described in the present invention, the unfolding component includes an equipment shell arranged on the top of the detection equipment body, a detection door panel rotatably arranged on the equipment shell, and a data collection component arranged on the top of the equipment shell.

[0010] As a preferred solution of the soil organic matter rapid detection device described in the present invention, the drying component includes a motor 1 arranged on one side of the equipment housing, an eccentric disk arranged at the output end of the motor 1, a rotating ring rotatably arranged at the other end of the eccentric disk, a linkage rod arranged on the outer diameter of the rotating ring, a linkage plate arranged on the linkage rod, a brush plate arranged on the linkage plate, and a blanking plate arranged at the other end of the rotating ring.

[0011] As a preferred solution of the soil organic matter rapid detection device described in the present invention, a drying plate is arranged inside the equipment housing, a feed opening is arranged on the drying plate, and the feed opening is slidably connected to the feed plate, a rotation auxiliary part is arranged on the other side of the feed plate, and the rotation auxiliary part is rotatably connected to the equipment housing.

[0012] As a preferred solution of the soil organic matter rapid detection device of the present invention, a humidity sensor is arranged on the top of the drying plate, and the humidity sensor is connected to the data collection unit.

[0013] As a preferred solution of the soil organic matter rapid detection device of the present invention, a heating plate is arranged inside the device housing, and the heating plate cooperates with the drying plate.

[0014] As a preferred solution of the soil organic matter rapid detection device of the present invention, a conical guide plate is arranged inside the device housing, and the conical guide plate cooperates with the drying plate.

[0015] As a preferred solution of the soil organic matter rapid detection device described in the present invention, the grinding assembly includes a fixed plate arranged inside the equipment housing, a conical grinding disc arranged on the fixed plate, a conical rotating disc rotatably arranged on the conical grinding disc, a material guide hole arranged on the conical rotating disc, a transmission rod arranged at the bottom of the conical rotating disc, a second motor arranged at the bottom of the transmission rod, a stabilizing plate arranged at the bottom of the second motor, and a supporting clip arranged on the stabilizing plate, and the supporting clip is connected to the equipment housing.

[0016] As a preferred solution of the soil organic matter rapid detection device of the present invention, wherein: a filter hole is arranged inside the conical grinding disc, a grinding guide bar is arranged next to the filter hole, and the grinding guide bar is connected to the conical grinding disc.

[0017] In view of the fact that the soil organic matter detection device mentioned above or in the prior art cannot quickly detect the soil, resulting in a slow detection time and complicated and cumbersome pretreatment operations, this detection method is proposed:

[0018] During the soil detection process, the detection door panel is opened to spread the collected sample soil on the top of the drying plate, and the detection door panel is closed, the heating plate starts to dry the sample soil, and the moisture inside the soil is constantly detected by the humidity sensor, and the data is transmitted to the control component for control and display;

[0019] After the moisture inside the soil reaches the standard, the motor starts to work, causing the eccentric disk to move the discharge plate in an arc, causing the discharge plate to slide out from the discharge port on the drying plate and be dislocated, so that all the soil spread on the top of the drying plate falls down through the discharge port. While the discharge plate moves, the linkage rod also moves the linkage plate and the brush plate downward in an arc to scrape the remaining soil on the top of the drying plate, so that all the soil on the top of the drying plate falls down;

[0020] The soil falls into the conical guide plate, is uniformly guided by the conical guide plate, and is introduced into the conical rotating disk. It falls into the gap between the conical rotating disk and the conical grinding disk through the guide hole inside the conical rotating disk. When the conical rotating disk is rotated by motor 2, the soil falling between the conical rotating disk and the conical grinding disk moves along the grinding guide strip to start grinding the soil. When the particles of the soil are smaller than the filter holes, the grinding is completed and the soil falls into the reaction box. Water is added to the reaction box through the water tank. At the same time, the potassium dichromate storage component adds potassium dichromate to the reaction box to start reaction detection of the soil. The reaction collection component collects and analyzes data of the soil reacting in the reaction box, and transmits the results of the soil detection to the control component for display, so that the soil can be quickly detected.

[0021] The beneficial effects of the present invention are as follows: by integrating multiple steps such as drying, grinding and reaction detection, the efficiency and convenience of soil detection are improved; the drying component accelerates the evaporation of water inside the soil, and the humidity sensor monitors the soil humidity in real time to ensure that the soil meets the specified drying requirements. Once the standard is met, the system automatically transports the soil to the conical guide plate and guides the grinding component for grinding. The cooperation of the conical rotating disk and the conical grinding disk inside the grinding component realizes the continuous guidance and grinding of the soil, and only soil particles smaller than 3mm can fall into the reaction box for subsequent detection. The detection results are also displayed in real time through the control component, further improving the accuracy and convenience of the detection, and can ensure that the soil particles are not detected until they meet the standard, and continue to be ground if they do not meet the standard, thereby avoiding the detection error caused by the excessive size of the soil particles, effectively solving the problem of complex and time-consuming pretreatment operations in traditional soil detection, and realizing fast and accurate soil detection.

DETAILED DESCRIPTION

[0034] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0035] Example 1, reference Figure 1 - Figure 3 , which is the first embodiment of the present invention, provides a soil organic matter rapid detection device, which includes: a main unit 100, a drying and grinding unit 200 and a detection reaction unit 300.

[0036] The main unit 100 includes a detection device body 101, a control unit 102 disposed on the detection device body 101, and an unfolding component 103 disposed on the top of the detection device body 101. When testing the soil, the unfolding component 103 on the detection device body 101 is unfolded, and then the collected soil sample is placed on the surface of the internal drying component 201, and the sample soil is flattened and evenly placed on the surface of the drying component 201, and the unfolding component 103 is closed to start pre-processing the soil before testing;

[0037] The drying and grinding unit 200 includes a drying component 201 arranged inside the unfolding component 103, a conical guide plate 202 arranged at the bottom of the drying component 201, and a grinding component 203 arranged at the bottom of the conical guide plate 202, and the conical guide plate 202 and the grinding component 203 are both connected to the unfolding component 103. After the soil sample is spread on the drying component 201, the drying component 201 starts to work, and the soil sample is dried by the heating plate 201l inside the drying component 201 to accelerate the evaporation of the moisture inside the soil sample. At the same time, the moisture inside the soil is monitored in real time by the humidity sensor 201i. After the moisture inside the soil reaches the standard, the drying component 201 automatically unloads the soil sample spread on the surface, so that the soil sample is uniformly collected inside the conical guide plate 202 and evaporating the soil sample through the conical guide plate 202. The plate 202 uniformly guides the collected soil samples and transports them to the inside of the grinding component 203. The conical rotating disk 203b and the conical grinding disk 203d inside the grinding component 203 begin to work together to grind the incoming soil. During the grinding process, because the conical grinding disk 203d is provided with uniform filtering holes 203f inside, and the hole diameter of the filtering holes 203f is less than 3mm, the soil samples ground inside the conical grinding disk 203d can only pass through the filtering holes 203f and fall into the detection reaction unit 300 below if the particles are smaller than 3mm. The soil samples larger than 3mm are further ground by the cooperation of the conical rotating disk 203b and the conical grinding disk 203d, so that the particle sizes of the soil samples to be tested all meet the standards, and the particles of the soil samples are prevented from being too large and affecting the accuracy of the test.

[0038] The detection reaction unit 300 includes a reaction box 301 arranged inside the detection device body 101, a potassium dichromate storage unit 302 arranged on one side of the reaction box 301, a data collection unit 303 arranged at the rear end of the potassium dichromate storage unit 302, and a water tank 304 arranged at the other end of the data collection unit 303, and the data collection unit 303 is electrically connected to the control unit 102. After the soil sample is dried and ground, it falls into the reaction box 301. At the same time, the water tank 304 adds water to the reaction box 301 to dilute the water and the soil sample. The potassium dichromate storage unit 302 also starts to add potassium dichromate solution to the reaction box 301 to react with the soil sample and start to detect the soil. At the same time, when the soil reacts, the data collection unit 303 and the reaction collection unit 303a collect the soil reaction results inside the reaction box 301, and transmit the data to the control unit 102, and the control unit 102 integrates and displays the results of the soil detection.

[0039] During use, when testing the soil, the unfolding component 103 on the detection device body 101 is unfolded, and then the collected soil sample is placed on the surface of the internal drying component 201, and the sample soil is spread out and evenly placed on the surface of the drying component 201. After closing the unfolding component 103, the soil pre-testing pretreatment is started. After the soil sample is spread out on the drying component 201, the drying component 201 starts to work, and the soil sample is dried by the heating plate 2011 inside the drying component 201 to accelerate the evaporation of the moisture inside the soil sample. At the same time, the moisture inside the soil is monitored in real time by the humidity sensor 201i. After the moisture inside the soil reaches the standard, the drying component 201 automatically unloads the soil sample spread out on the surface, so that the soil samples are uniformly collected on the drying component 201. The conical guide plate 202 guides the collected soil samples uniformly and transports them to the grinding assembly 203. The conical rotating disk 203b and the conical grinding disk 203d inside the grinding assembly 203 start to work together to grind the incoming soil. During the grinding process, because the conical grinding disk 203d is provided with uniform filtering holes 203f inside, and the hole diameter of the filtering holes 203f is less than 3mm, the soil samples ground inside the conical grinding disk 203d can only pass through the filtering holes 203f if the particles are smaller than 3mm and fall into the detection reaction unit 300 below. The soil samples larger than 3mm are further ground by the cooperation of the conical rotating disk 203b and the conical grinding disk 203d, so that the particle sizes of the soil samples to be tested all meet the standards.

[0040] After the soil samples are dried and ground, they are uniformly dropped into the reaction box 301. At the same time, the water tank 304 adds water to the reaction box 301 to dilute the water and the soil sample. The potassium dichromate storage component 302 also starts to add potassium dichromate solution to the reaction box 301 to react with the soil sample and start to test the soil. At the same time, when the soil reacts, the data collection component 2 303 and the reaction collection component 303a collect the soil reaction results in the reaction box 301 and transmit the data to the control component 102. The control component 102 integrates and displays the results of the soil test, which effectively solves the problem of complex and time-consuming pre-processing operations in traditional soil testing and realizes fast and accurate soil testing.

[0041] Example 2, reference Figure 1 - Figure 8 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: the unfolding component 103 includes an equipment housing 103a arranged on the top of the detection equipment body 101, a detection door plate 103b rotatably arranged on the equipment housing 103a, and a data collection component 103c arranged on the top of the equipment housing 103a. When testing the soil sample, the detection door plate 103b is opened to spread the soil sample on the top of the drying component 201, and the detection door plate 103b is closed. The component 201 includes a motor 201a arranged on one side of the equipment housing 103a, an eccentric disk 201b arranged at the output end of the motor 201a, a rotating ring 201c rotatably arranged at the other end of the eccentric disk 201b, a linkage rod 201e arranged on the outer diameter of the rotating ring 201c, a linkage plate 201g arranged on the linkage rod 201e, and a linkage plate 201 g, and the blanking plate 201d arranged at the other end of the rotating ring 201c. After the soil sample is spread on the surface of the drying plate 201f, the heating plate 201l starts to dry the soil sample spread on the surface of the drying plate 201f. At the same time, a humidity sensor 201i is arranged on the top of the drying plate 201f. When the heating plate 201l dries the soil on the surface of the drying plate 201f, the humidity sensor 201i monitors the moisture situation inside the soil sample in real time, so that the soil sample can be dried quickly, and by the method of spreading it on the surface of the drying plate 201f, the drying is made more uniform, and the humidity sensor 201i monitors the humidity changes of the soil in real time, which accelerates the evaporation of moisture inside the soil, and the humidity sensor 201i monitors the soil humidity in real time to ensure that the soil meets the specified drying requirements, which is a guarantee for subsequent soil testing.

[0042] Compared with Example 1, further, a drying plate 201f is provided inside the device housing 103a, a feed opening 201f-1 is provided on the drying plate 201f, and the feed opening 201f-1 is slidably connected to the feed plate 201d, a rotation auxiliary part 201d-1 is provided on the other side of the feed plate 201d, and the rotation auxiliary part 201d-1 is rotatably connected to the device housing 103a, a humidity sensor 201i is provided on the top of the drying plate 201f, and the humidity sensor 201i is connected to the data collection part 103c, a heating plate 201l is provided inside the device housing 103a, and the heating plate 201l cooperates with the drying plate 201f, and after the humidity of the soil sample on the surface of the drying plate 201f reaches the requirement, the motor 1 201a starts to work, so that the eccentric disk 2 01b starts to move in an arc with the rotating ring 201c, and the unloading plate 201d also moves with the movement of the rotating ring 201c, so that the unloading plate 201d falls off from the unloading port 201f-1 inside the drying plate 201f, and the unloading plate 201d moves to the bottom of the drying plate 201f to form a dislocation, and the soil samples on the surface of the drying plate 201f all fall down. At the same time, when the rotating ring 201c moves, the linkage rod 201e also moves downward with the linkage plate 201g and the brush plate 201h, so that the brush plate 201h can clean the soil samples remaining on the surface of the drying plate 201f, so that all the soil samples on the surface of the drying plate 201f fall down, thereby completing the drying and automatic transportation of the soil samples, and entering the next step of processing.

[0043] During use, when testing the soil sample, open the testing door panel 103b and spread the soil sample on the top of the drying component 201, and close the testing door panel 103b to start the pretreatment of the soil sample for testing. After the soil sample is spread on the surface of the drying plate 201f, the heating plate 201l starts to dry the soil sample spread on the surface of the drying plate 201f. At the same time, a humidity sensor 201i is arranged on the top of the drying plate 201f. When the heating plate 201l dries the soil on the surface of the drying plate 201f, the humidity sensor 201i monitors the moisture condition inside the soil sample in real time. The humidity sensor 201i monitors the humidity change of the soil in real time, which accelerates the evaporation of moisture inside the soil. After the humidity of the soil sample on the surface of the drying plate 201f reaches the requirement, the motor 201a starts to work. The eccentric disk 201b starts to move in an arc with the rotating ring 201c, and the unloading plate 201d also moves with the movement of the rotating ring 201c, so that the unloading plate 201d falls off from the unloading port 201f-1 inside the drying plate 201f, and the unloading plate 201d moves to the bottom of the drying plate 201f to form a misalignment, and the soil samples on the surface of the drying plate 201f all fall down. At the same time, when the rotating ring 201c moves, the linkage rod 201e also moves downward with the linkage plate 201g and the brush plate 201h, so that the brush plate 201h can clean the soil samples remaining on the surface of the drying plate 201f, so that the soil samples on the surface of the drying plate 201f all fall down, thereby completing the drying of the soil samples and automatically conveying them to start the pretreatment of the soil samples for testing.

[0044] The remaining structures are the same as those of Example 1.

[0045] Example 3, reference Figure 1 - Fig.10 , which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that a conical guide plate 202 is provided inside the equipment housing 103a, and the conical guide plate 202 cooperates with the drying plate 201f. After the soil samples are dried, they all fall into the conical guide plate 202, and are uniformly collected and guided by the conical guide plate 202, and are transported to the grinding assembly 203 for grinding.

[0046] Compared with Example 2, further, the grinding assembly 203 includes a fixed plate 203a disposed inside the device housing 103a, a conical grinding disc 203d disposed on the fixed plate 203a, a conical rotating disc 203b rotatably disposed on the conical grinding disc 203d, a material guide hole 203c disposed on the conical rotating disc 203b, a transmission rod 203g disposed at the bottom of the conical rotating disc 203b, a motor 203h disposed at the bottom of the transmission rod 203g, a stabilizing plate 203l disposed at the bottom of the motor 203h, and a supporting clip 203i disposed on the stabilizing plate 203l, and the supporting clip 203i is connected to the device housing 103 a connection, the soil sample is guided by the conical guide plate 202 and transported to the inside of the conical rotating disk 203b, and is transported to between the conical rotating disk 203b and the conical grinding disk 203d through the guide hole 203c inside the conical rotating disk 203b, and the motor 203h works to make the conical rotating disk 203b start to rotate inside the conical grinding disk 203d, and the soil sample starts to be ground. At the same time, because the conical grinding disk 203d is provided with a grinding guide strip 203e inside, the soil sample falling between the conical rotating disk 203b and the conical grinding disk 203d will automatically move and be driven by the rotating conical rotating disk 203b to be ground.

[0047] Furthermore, a filter hole 203f is provided inside the conical grinding disk 203d, and a grinding guide bar 203e is provided next to the filter hole 203f, and the grinding guide bar 203e and the conical grinding disk 203d. During the process of grinding the soil, the grinding guide bar 203e provided on the surface of the conical grinding disk 203d can make the soil between the conical rotating disk 203b and the conical grinding disk 203d move along the grinding guide bar 203e, and under the restriction of the filter hole 203f provided on the surface of the conical grinding disk 203d, because the aperture of the filter hole 203f is 3mm, when the soil sample between the conical rotating disk 203b and the conical grinding disk 203d is ground, those smaller than the aperture of the filter hole 203f can pass through, and those larger than the aperture will continue to be ground, which can effectively prevent the generation of large-particle soil samples when the soil samples are tested later, thereby affecting the test results.

[0048] During use, after the soil samples are dried, they all fall into the interior of the conical guide plate 202, and are uniformly collected and guided and transported by the conical guide plate 202, and transported to the interior of the grinding assembly 203 for grinding processing. The soil samples are guided by the conical guide plate 202 to the interior of the conical rotating disk 203b, and are transported to between the conical rotating disk 203b and the conical grinding disk 203d through the guide hole 203c inside the conical rotating disk 203b, and the motor 203h is operated to make the conical rotating disk 203b start to rotate inside the conical grinding disk 203d, and the soil samples begin to be ground. At the same time, because the conical grinding disk 203d is provided with a grinding guide strip 203e inside, the soil samples that fall between the conical rotating disk 203b and the conical grinding disk 203d will automatically move and be The rotating conical rotating disk 203b drives the grinding. During the grinding process of the soil, the grinding guide strip 203e arranged on the surface of the conical grinding disk 203d can make the soil between the conical rotating disk 203b and the conical grinding disk 203d move along the grinding guide strip 203e, and under the restriction of the filter hole 203f arranged on the surface of the conical grinding disk 203d, because the aperture of the filter hole 203f is 3mm, when the soil sample between the conical rotating disk 203b and the conical grinding disk 203d is ground, those smaller than the aperture of the filter hole 203f can pass through, and those larger than the aperture continue to be ground, which can effectively prevent the detection error caused by the excessively large soil particles when the soil samples are tested in the later stage, and effectively solve the problem of complex and time-consuming pretreatment operations in traditional soil testing.

[0049] The remaining structure is the same as that of Example 2.

[0050] Example 4, reference Figure 1 - Fig.10 , which is the fourth embodiment of the present invention. This embodiment is different from the third embodiment in that: during the soil detection process, the detection door panel 103b is opened to spread the collected sample soil on the top of the drying plate 201f, and the detection door panel 103b is closed, and the heating plate 201l starts to dry the sample soil, and the moisture inside the soil is constantly detected by the humidity sensor 201i, and the data is transmitted to the control component 102 for control and display. After the soil sample is dried and ground pre-processed, the soil sample enters the reaction box 301, and the solution is added to the reaction box 301 through the water tank 304 and the potassium dichromate storage component 302, and the soil sample in the reaction box 301 starts to react and detect, and the reaction collection component 303a collects the reaction of the soil sample, and the data collection component 2 303 transmits the collected data to the control component 102 for display of the soil detection result.

[0051] Compared with Example 3, further, after the moisture content inside the soil reaches the standard, the motor 201a starts working, so that the eccentric disk 201b moves with the unloading plate 201d in an arc, so that the unloading plate 201d slides out from the unloading port 201f-1 on the drying plate 201f and is displaced, so that all the soil spread on the top of the drying plate 201f falls down through the unloading port 201f-1. While the unloading plate 201d moves, the linkage rod 201e also moves downward with the linkage plate 201g and the brush plate 201h in an arc to scrape the remaining soil on the top of the drying plate 201f, so that all the soil on the top of the drying plate 201f falls down.

[0052] Furthermore, the soil that falls inside the conical guide plate 202 is uniformly guided by the conical guide plate 202, introduced into the conical rotating disk 203b, and falls into the gap between the conical rotating disk 203b and the conical grinding disk 203d through the guide hole 203c inside the conical rotating disk 203b. When the motor 203h rotates the conical rotating disk 203b, the soil that falls between the conical rotating disk 203b and the conical grinding disk 203d moves along the grinding guide strip 203e. The soil starts to be ground automatically. When the soil particles are smaller than the filter holes 203f, the grinding is completed and falls into the reaction box 301. Water is added to the reaction box 301 through the water tank 304. At the same time, the potassium dichromate storage component 302 adds potassium dichromate to the reaction box 301, and the soil reaction detection begins. The reaction collection component 3031 collects and analyzes the data of the soil reacted in the reaction box 301, and transmits the soil detection results to the control component 102 for display.

[0053] During use, during soil testing, the testing door panel 103b is opened to spread the collected sample soil on the top of the drying plate 201f, and the testing door panel 103b is closed. The heating plate 201l starts to dry the sample soil, and the moisture inside the soil is constantly detected through the humidity sensor 201i, and the data is transmitted to the control component 102 for control and display. After the soil sample is dried and ground pre-processed, the soil sample enters the reaction box 301, and the solution is added to the reaction box 301 through the water tank 304 and the potassium dichromate storage component 302. The soil sample inside the reaction box 301 starts to react and detect, and the reaction collection component 303a collects the reaction of the soil sample. The data collection component 2 303 transmits the collected data to the control component 102 for soil detection results display, which improves the soil quality. In order to improve the efficiency and convenience of soil detection, the drying component 201 accelerates the evaporation of water inside the soil, and the humidity sensor 201i monitors the soil humidity in real time to ensure that the soil meets the specified drying requirements. Once the standard is met, the system automatically transports the soil to the conical guide plate 202 and guides the grinding component 203 for grinding. The cooperation of the conical rotating disk 203b and the conical grinding disk 203d inside the grinding component 203 realizes the continuous guidance and grinding of the soil, and only soil particles smaller than 3mm can fall into the reaction box for subsequent detection. The control component 102 displays the detection results in real time, further improving the accuracy and convenience of the detection, and can ensure that the soil particles are detected only after they meet the standards, and continue to be ground if they do not meet the standards, thereby avoiding the detection error caused by the excessive size of the soil particles, and effectively solving the problem of complex and time-consuming pretreatment operations in traditional soil detection.
