Abstract
Soil information approach is associated with the integrated agricultural rendering practice. Nitrogen (N), Phosphorus (P), and Potassium (K) are the imperative supplement plants demands in the bulkiest extent. The stereotyped technique (Physicochemical investigation) used for disclosure of nitrogen in soil is compound and stagnant. Ample variety of N, P, K nutriments in the soil assures excellent plant growth which results in high quality produce with enhanced annual production yields. Farm supervisors also have a condemning liability of estimating the NPK levels in soil. This paper addresses the review of the methods that has been used for determining the soil N, P, K contents from the soil as over-fertilization results in groundwater pollution or toxic aggregation of enzymatics in the soil.
