Design And Implementation of Portable Soil Fertility Testing Device

The main goal of the project is to design a portable soil fertility testing device which helps the farmer in deciding the best fertilizer to use for their farm depending on the NPK (Nitrogen, Potassium and Phosphorous) value of the soil. To grow and obtain best yield of crop, the most essential elements are carbon(C), hydrogen(H), oxygen(O) nitrogen (N), phosphorus(P), potassium(K), if the soil is fertile and nutrient rich then the farmer is at an advantage of growing any crop and earn some workable profit. In the last six decades, the consumption of reactive nitrogen (Nr) in the form of fertilizer in India has been growing rapidly, while the nitrogen use efficiency (NUE) of cropping systems has been decreasing as it causes a deficiency of Sodium and Potassium in the soil. Our Project aims to read the number of macronutrients (NPK) in the soil at a faster pace compared to the traditional existing chemical analysis mechanism.
