Soil fertility appraisal of Bhandara block of Maharashtra using geospatial techniques

Abstract

The geospatial techniques are playing a vital role in spatial assessment of soil nutrient variabilities. Study was undertaken to assess the available macronutrient and micro-nutrient status of Bhandara tehsil of Maharashtra with the help of GPS based one hundred forty-seven soil samples during the period of 2015-2018. The results recorded that pH of 70% samples were neutral in nature, non-saline and 72% samples were deficient in terms of oxidizable organic carbon. The mean values of 291.70 kg ha-1, 37.07 kg ha-1, 531.33 kg ha-1, 11.94 kg ha-1, 0.35 mg kg-1, 4.44 mg kg-1, 1.28 mg kg-1, 7.66 mg kg-1 and 1.52 mg kg-1 for N, K, P, S, Zn, Fe, Cu, Mn and B respectively was recorded. The nutrient index values of nitrogen, phosphorus, potassium and sulphur were 1.5, 2.6, 3.0 and 1.6 respectively. In case of micronutrients, nutrient index values of zinc, iron, copper, manganese and boron were 1.0, 1.4, 2.8, 2.9 and 1.00 respectively.
