The macro and micro nutrients of the samples gives the information about the fertility of the soil, and accordingly the crop production are correlated. In this Physico-chemical study, soil samples of four states like Rajasthan, Haryana, Uttar Pradesh and Punjab of north India is collected and tested for number of parameter like available Organic Carbon (OC), pH, Electrical Conductivity (EC), Phosphorus (P2O5), Nitrogen (N), Sulphur (S) and Potassium (K2O). This study builds an understanding about state wise variation of micro nutrients in agricultural land which can be further correlated with the crop production and its economy. The finding of the study reveals that out of four selected states, Haryana takes lead in pH value, Rajasthan takes lead in EC, K and S, and Uttar Pradesh takes lead in OC, P.
