Soil fertility appraisal of some selected villages in Kirmira block of Jharsuguda District under western-central table land agro-climatic zone of Odisha, India

Abstract

A soil fertility status inventory work was carried out in some villages of Kirmira block of Jharsuguda district located in the Western Central Table Land Agro Climatic Zone of Odisha, India. Results showed that soil pH ranged between 4.3 and 6.4 and electrical conductivity of the entire study area remained below 1 dSm-1. Soil Organic Carbon (SOC) content ranged between 0.17 to 0.88%. Available nitrogen content in these soils was found to be varied between 84.0 to 398.0 kg ha-1. Available Bray’s phosphorus content varied from 0.75 to 67.10 kg ha-1. Available soil potassium content varied widely from 90 to 500 kg ha-1. CaCl2 extractable soil sulphur varied from 0.14 to 12.49 mg kg-1. DTPA extractable micronutrients (Fe, Mn, Cu and Zn) varied from 32.62 to 192.20, 28.08 to 220.50, 0.48 to 2.86, and 0.56 2.38 mg kg-1 respectively. Hot water soluble boron content ranged from 0.13 to 0.88 mg kg-1. All the figures in the lower range were found in upland soils while the higher values for all the parameters were found in low land soils.
