Nutrient availability of soil under inceptisols from Washi Tahsil of Osmanabad district of Maharashtra, India

Abstract

The present investigation was carried out during the 2012-13 to study the Nutrient availability of soil under Inceptisols from Washi tahsil of Osmanabad District of Maharashtra. For this purpose total 60 representative soil samples were collected from 30 villages and two soil samples from each village of Washi tahsil were collected according to their representative depths. From each village 2 soil samples Inceptisols (10-30 cm) were collected. In physical analysis Bulk density, Particle density, Porosity were studied. Average bulk density, particle density and porosity was ranges from 1.13 to 1.86 Mg m-3, 2.03 to 2.96 Mg m-3 and 20 to 56 per cent respectively. In chemical analysis viz., pH, EC, organic carbon, free calcium carbonate, macronutrient and micronutrient were analyzed. Available N, P and available K were varied from 42.00 to 343.00 kg ha-1, 4.64 to 48.03 kg ha-1and 157.90 to 967.60 kg ha-1. Exchangeable Ca++ and exchangeable Mg++ content ranged from 17 to 58 cmol (P+) kg-1 and 2 to 28 cmol (P+) kg-1, respectively and available S ranged from 3.95 to 50.70 mg kg-1. The DTPA- Fe, DTPA-Mn, DTPA-Zn and DTPA-Cu in soils varied from 0.48 to 4.98 mg kg-1, 1.3 to 12.4 mg kg-1, 0.1 to 1.35 mg kg-1 and 0.63 to 6.66 mg kg-1, respectively. HWS-B ranges from 0.05 to 1.15 mg kg-1.
