*2.2.1 Farmers services*

In-order to extend the facilities to the farmer who is involved in organic farming, the mobile application is developed which will provide access to the farmer services on selecting user login option as farmer. Further the farmer can perform several activities in the application based on their choice. Each activity is explored in the following.

1.**IoT Enabled Sensor for Soil and Water [SWA] Analysis** – Soil and water are important factor that need to considered for effective growth of plants, so it is necessary to analyze these two viz. soil and water, for healthy and sustainable farming. Since the testing laboratories are located one per district and consume more time and delayed response from the testing laboratories for the reports. Hence the village farmers face difficulty in getting tested these parameters from the laboratory. So, the proposed IoT based smart farming mobile application helps in measuring the primary soil nutrients [NPK] and pH value of water using IoT enabled sensor implanted at different locations of the agricultural lands and water reservoirs. This automation will save the time and cost of the farmers. The block diagram of IoT enabled Soil NPK and pH of Irrigation Water testing is shown in below **Figure 2**.

**Figure 2.** *Block diagram of soil NPK and pH of irrigation water analysis.*

The prototype of IoT based soil NPK and pH of irrigation water testing makes use of hardware components like IoT enable Microcontroller, Ethernet shield, soil moisture, temperature and humidity sensor, Color Sensor, Water pH sensor and power supply.

	- a.**About APMC** This module provides information about the Agricultural Produce Market Committee (APMC).
	- b.**Upload SWA Report** It provides a facility for farmer to upload the soil and water analysis report of the agriculture land to the APMC admin for knowing the best and suitable crop for growing to get more yield.
	- c.**View Crop Suggestion and Get Organic Certificate** Admin will suggest the best and profitable crop to the farmers based on their uploaded SWA reports. Admin also offers an agreement clause and Organic certificate to the farmers which provides fair marketing for the farmers yield and also provide insurance facility for the crop.
	- d.**Signing of Agreement** It provides an option for the farmers to sign the agreement with the APMC. According to this agreement, the yield of the farmer was purchased by APMC at fixed price as mentioned in the agreement provided, if farmers agrees to grow crops that are suggested by APMC admin. The agreement clause also includes the Insurance for the crops in case yield loss due to occurrence of natural disaster like flood, droughts etc. Farmers will get the minimum amount per acre as mentioned in the agreement.
	- e.**Sell Crops** It gives an internet showcasing office/market to the farmer to offer their yields to the APMC at fixed cost.
