Soil Fertility Status of Some Villages in Khordha and Bhubaneswar Block of Khordha District under North Eastern Ghat Agro Climatic Zone of Odisha, India

Abstract

A soil fertility status inventory work was carried out in some villages of Khordha and Bhubaneswar blocks belonging to Khordha district located in the North-Eastern Ghats Agro Climatic Zone of Odisha, India. Results show that soil texture of the villages under investigation varied from loamy sand to clay loam. Clay content varied from 2.4 to 34.0 percent. Soil pH ranged between 4.24 and 6.93 and electrical conductivity of the entire study area remained below 1 dSm-1. Soil Organic Carbon (SOC) content ranged between 1.1 to 11.6 g kg-1. Available nitrogen content in these soils was found to be varying between 50.0 to 225.0 kg ha-1. Available Bray’s phosphorus content varied from 11.3 to 2326.5 kg ha-1. Available soil potassium content varied widely from 37.6 to 458.3 kg ha-1. CaCl2extractable soil sulphur varied from 2.17 to 11.02 mg kg-1. Hot water soluble boron content ranged from 0.91 to 2.68 mg kg-1. All the figures in lower range were found in upland soils while the higher values for all the parameters were found in low land soils.
