Comparative Study of Soil Fertility Based on SFM Computational Model for IB-INW and IC-HAPI Zone

In agriculture, soil is a critical component. This study compares the fertilization status of IC-HAPI zone with neighbouring IB-INW zone in agricultural land and waste land categories. IB-INW zone and IC-HAPI zone located in Rajasthan, India, were selected, with two different agriculture productions. Soil contents, calcium carbonate, CEC, pH, EC, OC, N, P, K, Zn, Fe, Cu and Mn were compared. The fertilization status difference in soil of IB-INW and IC-HAPI zone was evaluated using the deterioration index (DI). Compared to soil of IB-INW zone, overall DI values of +288.2% (FLS) and +274.75% (WLS) were observed in soil of IC-HAPI. In the present study, -45.16% (FLS) and -58.45% (WLS) DI value of calcium carbonate were analysed in IC-HAPI. In farmland soil, positive DI values of nitrogen and phosphorus +25.25% and +24.23% were observed, respectively. While in case of nitrogen and phosphorus, positive +16.83% and +46.04% DI values were analysed in wasteland soil of IC-HAPI. The SFM model showed the deficiency of nitrogen, phosphorus and organic carbon were more pronounced in both zones. Model helps to predict soil fertilization status, and is able to solve nutrient related problems by micro-organisms. These micro-organisms can help to enhance and maintain the soil fertility and crop yield in the IC-HAPI and IB-INW zone. This experiment will help and encourage to researchers, agronomists or farmers, who are interested in evaluation of the agronomic, nutrient management and soil fertility management to sustain present and future agriculture. In this study, we calibrate the comparison of soil parameters as a tool for understanding and evaluating the fertilization status relationship between IB-INW and IC-HAPI zone of Rajasthan also, using a computational model.
