Soil Nutrient Survey and Google Map Cartography

Soil Health is important for plant growth and the productivity of farming. There is an important need to determine NPK i.e., Nitrogen, Phosphorus, and Potassium (macro-nutrients), soil moisture, electrical conductivity, and pH value to determine soil health. Measurement of nutrient contents of soil is necessary to decide the need for adding an additional amount of such nutrients to increase soil fertility. This improves the quality of the soil and hence yields a good quality crop. Such soil health card information needs to be dynamic and is very important to monitor for every crop season. This work quantifies the soil nutrient values in the soil sample and maps the data using the Global Positioning System (GPS) to the specific location from where the sample has been collected. This process dynamically works and updates the soil health parameters every season. Besides, additional soil health parameters like pH, moisture content, and total dissolved solids (TDS) are also measured dynamically and mapped to the location. The mapping of the soil health to a location will help the farmer in deciding what crop to grow. This will help in increasing the yield of the crop and meet the increasing food demand.
