Delineation and GPS-GIS based mapping of available macro and micronutrients of soils of Lakhani block of Bhandara, Maharashtra

Abstract

The present experiment for assessing and mapping of available macro and micronutrients status was conducted in 101 villages of Lakhani block of Bhandara district in Maharashtra state of India, located in north deccan Maharashtra lower plateau in ‘Wainganga’ sub-basin of ‘Godawari’ basin, during the pre-monsoon season of 2015-2018. The collected and processed composite soil samples were analyzed for some physico-chemical properties, available macro and micronutrient status. The results showed that pH, EC, OC, N, K, P, S, Zn, Fe, Cu, Mn and B were ranging from 6.00-7.8, 0.1-1.9 dSm-1, 0.27-0.78%, 180.7-513.9 kg ha-1, 9.7-132.0 kg ha-1, 169.1-803.9 kg ha-1, 0.1-63.1 kg ha-1, 0.2-1.7 mg kg-1, 0.4-24.2 mg kg-1, 0.6-4.4 mg kg-1, 2.1-19.3 mg kg-1 and 0.1-2.3 mg kg-1 respectively. The nutrient index of available nitrogen, phosphorus, potassium and sulphur was 1.4, 2.4, 2.9 and 1.6 respectively. The nutrient index values for available Zn, Fe, Cu, Mn and B were 1.1, 1.8, 3.0, 2.9 and 1.0 respectively.
