Soil Fertilization Status Assessment for IC-HAPI Zone of Rajasthan with SFM Computational Model

Abstract

Description of soil properties is required to improve soil and environment management for reducing problems in soil fertility. This study was based on the investigation of the soil physical and chemical properties in IC-HAPI zone of Rajasthan province. Collected soil samples were evaluated for different parameters, viz. pH, electrical conductivity, essential nutrient concentration of N, P, K, organic matter, organic carbon, micronutrient concentration of iron (Fe), zinc (Zn), copper (Cu), manganese (Mn), cation exchange capacity (CEC), texture, and calcium carbonate (CaCO3). The positive DI value +45.45% was observed for manganese in WLS with respect to FLS. In WLS, positive DI values +44.58% and +34.78% were observed for phosphorus and organic carbon, respectively. Results of this study indicated that low status of organic carbon was found in 93% IC-HAPI zone. In IC-HAPI soils, the nitrogen was observed extremely low. For 71% zone, low concentrations of zinc were examined. According to model results, low fertilization status was examined for whole IC-HAPI zone. Despite in-depth investigation, the model presented in the present study has greatly ameliorated our knowledge about sustainable land management and fertilization status of soil. This study provides a new perspective in sustainable management of soil and land. In this study, we tried to improve the soil fertility and sustainability using bio-fertilizers after assessing the soil of IC zone on physical and chemical parameters.
