**4.4 Upload readings**

In Upload soil and water analysis (SWA) readings the details such as moisture, temperature, humidity and NPK value are filled as shown in **Figure 26** after clicking the upload button the details will be uploaded to the database for further processing. The APMC admin can use this information for crop and fertilizer prediction as shown in **Figure 27**.

### **4.5 View prediction and sign agreement**

The farmer can view the suitable crop and appropriate fertilizer as shown in **Figure 27** suggested by the admin. Along with this the admin offers an agreement proposal to the farmer. According to this agreement the farmer has to grow only those crops that are suggested by the admin, the purchasing price of the crop yield is fixed in the agreement before the farmer starts growing it and it also provides crop insurance

to the farmer. If the farmer agrees to stated agreement criteria to grow the suggested organic crop then he can sign the agreement as shown in **Figure 28** by just clicking I agree checkbox and submit button. The request is sent to admin for future operation.

#### **4.6 Selling and buying of organic crops**

Whenever the farmer wishes to sell the crop yield, he/she fills the details as shown in **Figure 29** the crop details will be stored in the database and when the admin login to app to buy the crops then these stored details will be retrieved and displayed to admin.

#### **4.7 Insurance**

Insurance is a means of protection from financial loss. The agreement provides the crop insurance to the farmer, to avail this facility farmer must have signed the agreement. It is given to the farmer whose yield is lost due to occurrences of unavoidable climatic conditions such as droughts, floods etc. to save the farmers from financial loss. Using this mobile app farmer can claim the insurance by providing the necessary details as shown in the **Figure 30**. The request is sent to the admin for approval, on verifying the details admin has the facility to approve or reject the insurance claim as shown in **Figure 30**.

This section shows the experimental results of complete implementation of the proposed method. The experiment is conducted in agriculture fields to measure real time values of soil parameter such as moisture, temperature, humidity and NPK nutrients

value and listed the read value in the **Table 3**. Further these values are used for predicting suitable crop and appropriate fertilizer. The yield of the organic farm is monitored with the help of Mobile and IoT enabled technology for the duration of one year and tabulated the observations, which indicated the production of the yield is increased and the soil fertility is also improved. The proposed methodology obtained the promising results for sustainable agriculture using soil and water nutrients and farmers get direct marketing to their increased organic products at APMC as per the agreement.
