The crop information may include information about a crop that was cultivated last time (for example, the previous year) (because there are crops that are adversely affected by rotation). The input soil is automatically analyzed in the soil analysis unit 16. And the soil information which is the analysis result,
The control unit 15 communicates with the information processing device 2 together with the crop information and the cultivated land information input from the information input / output unit 12.

The information input / output unit 12 is composed of, for example, a touch panel type display so that a customer can easily input necessary information in an interactive manner. Then, under the control of the control unit 15, a screen is displayed on the display for selecting environmental items such as the sun on the cultivated land, drainage, and whether or not greenhouse cultivation, and the planted area, and the like. The customer can input the cultivated land information of the planned cultivation area by selecting the corresponding item on the screen. After that (or before that), the information input / output unit 12 is a screen for selecting the type of crops to be cultivated in the cultivated land (and the type of crops previously cultivated) under the control of the control unit 15. , Which allows the customer to enter crop information.

The soil-crop DB 22 stores the kinds of crops suitable for cultivation in the soil and the kinds of plants not suitable for cultivation in accordance with the properties of the soil. These pieces of information are stored in the form of “adaptation rank” that is determined according to how suitable the crop is for soil properties. The conformity rank is created by the agricultural guidance organization and updated accordingly.

The crop-fertilization standard DB 23 stores fertilization standard information for each crop, and the fertilization standard information should be fertilized not only for each crop but also for each season, each region, and each soil property. The standard mixing ratio of fertilizer is shown. That is, the fertilization reference information is a reference value that represents an optimum type and mixing ratio of fertilizer for cultivating a certain crop A in a cultivated land with a certain soil property D in a certain region C in a certain season B. Fertilization standard information is also created by the agricultural guidance organization and updated as appropriate.

The fertilizer stock DB 24 stores the stock amount for each type of fertilizer stocked in the automatic fertilizer blending device 3 and the price per unit amount. Then, the stock amount for each type of fertilizer is subtracted based on the calculation result of the optimum fertilizer mixture determination unit 26, and the stock amount is added according to the fertilizer filling amount from the fertilizer distribution management unit 28.

The soil diagnosis unit 25 analyzes the soil properties of the soil (input from the soil sample input port 11) based on the soil information sent from the fertilizer vending machine 1. Then, referring to the soil-crop DB22, it is determined whether or not the soil property is suitable for cultivating the crop input by the customer, and the suitability rank of the determination result is stored in the customer DB21 and the analysis result report is made. The creation unit 27 is notified. Only when the cultivation of the crop is suitable for the soil, that is, when the compatibility rank is high, the optimum fertilizer mixture determination unit 26 is instructed to calculate the optimum fertilizer type, mixture ratio, and amount. The conforming rank is also sent to the analysis result report creating unit 27.

Based on this calculation command, the optimum fertilizer mixture determination unit 26 stores the fertilizer application stored in the crop-fertilization reference DB 23 based on the soil information, cultivated land information, and crop information transmitted from the fertilizer vending machine 1. Refer to the reference information,
Determine the type, mix proportion and amount of fertilizer per unit area required to grow the desired crop on the arable land desired by the customer. Then, referring to the planting area included in the cultivated land information, the amount of the mixed fertilizer is determined, and the finally determined type, mixing ratio, and amount of the fertilizer are used as the mixed fertilizer information as the fertilizer automatic mixing device 3 Communicate to. Further, the price of the sold fertilizer is determined based on the compound fertilizer information and the price information of the fertilizer stock DB 24, and the determined compound fertilizer information and the sold fertilizer price are sent to the analysis result report creating unit 27 and also to the customer DB 21. It is stored according to the customer. When the crop and soil properties do not match, that is, when the matching rank is determined to be low, the soil diagnosis unit 25
Notifies the analysis result report creating unit 27 of the matching rank and also notifies of crops that match the properties of the cultivated land. These pieces of information are also stored in the customer DB 21.

5 and the information from the optimum fertilization mixture determination unit 26, a soil diagnosis result report and a prescription for a customer are created as electronic data. Soil diagnosis section 2
The conformity rank of the soil and the crop determined in 5 and the soil analysis / analysis result are included, and when the conformity rank is low, the type of recommended crop suitable for the cultivated land is included. The prescription is created only when the conformity rank is good, and includes the type, blending ratio, and amount of fertilizer necessary for growing the crop in the cultivated land. If the conformity rank is good, the soil diagnosis result report may be included in the prescription. The soil diagnosis result report and prescription created as electronic data are notified to the fertilizer vending apparatus 1, displayed on the information input / output unit 12, and output from the printer 17 as a hard copy on request.

When the soil diagnosis result report includes information that the conformity rank is low, the customer refers to the recommended crop in the report and cultivates it on the information input / output unit 12. You can change the crop type and repeat the purchase procedure for the optimal compound fertilizer. If the prescription contains information that has a high conforming rank and therefore includes the price of the compound fertilizer, when the customer decides to purchase the fertilizer and turns on the fertilizer purchase button displayed in the information input / output unit 12, the information is displayed. Processor 2
The optimum fertilizer mixture determination unit 26 of (1) notifies the automatic fertilizer mixing device 3 of the type, the mixing ratio, and the amount of the fertilizer to be mixed, that is, the mixed fertilizer information. And fertilizer stock D
Subtract the stock amount of the corresponding type of fertilizer in B24.

Since the information processing device 2 can obtain the secular change of the soil property by referring to the history of the soil information of the cultivated land of the customer in the customer DB 21, the secular change information is included in the prescription. You can put it. At this time, if the customer's cultivated land is comparatively large, it is possible to input which point (plural points) of the cultivated land is the soil sample on the information input / output unit 12 of the fertilizer vending machine 1. ,
As a result, it is possible to obtain the secular change of soil properties at a plurality of points on one cultivated land.

The fertilizer distribution management unit 28 monitors the amounts of standard fertilizers of a plurality of types to be stocked in the automatic fertilizer blending device 3, and when the remaining amount of each standard fertilizer falls below a predetermined threshold value. , The fertilizer manufacturer and / or the fertilizer wholesaler are notified, and the fertilizer automatic compounding device 3 is managed so that the fertilizer is replenished.

In addition, in FIG. 5, the upper graph is a graphical representation of the analysis values of FIG. 4, and this graph may also be included in the soil diagnosis result report. The increase / decrease calculation of fertilizer is calculated in the optimum fertilizer mixture determination unit 26. As is clear from the table of FIG. 4 and the upper graph of FIG. 5, NO ₃ —N and potassium are excessive and phosphoric acid is insufficient from the standard value. Therefore, as shown in the calculation example in the lower part of FIG. 5, nitrogen and potassium are reduced by 8 kg and the phosphoric acid are increased by 5 kg per 10 ares, respectively, from the standard amount used.

Based on the calculation result of the increase / decrease of the fertilizer per unit area, the optimum fertilizer mixture determination unit 26 refers to the planted area and calculates the amount of the mixed fertilizer for the entire cultivated land. As a result, the type, mixing ratio and amount of fertilizer for the entire planted area are determined. Then, the optimum fertilizer combination determination unit 25 determines the usage amounts (packaging style × bag) of a plurality of standard mixed fertilizers having different component ratios based on the obtained fertilizer type, mixing ratio, and amount. The analysis result report creating unit 27 is notified of the result. The creation unit 27 creates a crop cultivation fertilization application plan as shown in FIG. 6, which is a part of the prescription, based on the notified standard use amount of the compound fertilizer. As shown in FIG. 6, this crop cultivation fertilization design document shows that the amount of the basic fertilizer (fertilizer used before planting the crop) and the additional fertilizer (fertilizer used from the middle stage to the latter stage of the crop cultivation) suitable for the crop to be cultivated. Amounts and times are shown separately.

While the preferred embodiment of the invention has been described, it will be apparent to those skilled in the art that the invention is susceptible to various modifications. For example, as described above, the fertilizer automatic vending apparatus 1 may be configured as a fertilizer order receiving device that receives only soil analysis and an order for the mixed fertilizer, and the mixed fertilizer may be delivered at another window or delivered at a later date. Further, the information processing device 2 may be built in the fertilizer vending machine 1.

As described above, the optimum fertilizer sales system according to the present invention grasps the compatibility between the crop to be cultivated and the cultivated land by analyzing the actual soil of the cultivated land, and based on that, Thus, the compound fertilizer for the crop can be optimized and sold. Therefore, the farmer
Since it is possible to easily obtain a fertilizer suitable for one's cultivated land and cultivated crop, it is possible to prevent poor growth of the crop due to excess or deficiency of the fertilizer. In particular, for farmers who have little experience in crop cultivation, such as when they cultivate crops due to their hobbies, etc., they can obtain the optimum crop type information for their own cultivated land. Since it is possible to purchase the optimum compound fertilizer for, it is possible to greatly reduce the failure of crop cultivation. In addition, it is possible to reduce environmental problems caused by excessive application of fertilizer.
