CORRELATION STUDIES ON AVAILABLE SULPHUR AND SOIL PROPERTIES (PH, EC AND OC) IN DIFFERENT SOIL TYPE OF MALKHARAUDA BLOCK UNDER JANJGIR-CHAMPA DISTRICT IN CHHATTISGARH, INDIAHareesh Kumar, P.K. Kurre, Bharat Lal Desmukh and K.K. Sahu
The study was carried out to evaluate the soil fertility status with respect to available sulphur nutrient status and its relationship with important physico-chemical characteristics in different soils of Malkharauda block under Janjgir-Champa district of Chhattisgarh during 2013-14. Grid based 1975 surface (0-15 cm depth) soil samples were collected using Global positioning system (GPS) from 110 villages of Malkharauda block. The soil samples were analyzed for pH, EC, OC and Sulphur. Most of the soil pH varied from 4.2 8.0 and indicated that soils were found to be moderately acidic to slightly acidic in reaction. The organic carbon content in these soils varied from 0.14 1.00 per cent which was observed to be medium to low in organic matter status. The electrical conductivity (EC) varied from 0.05 to 0.81 dS m-1 with a mean value of 0.21 dS m-1 at 25oC of the Malkharauda block. The available sulphur status varied from 7.56-89.32 kg ha- 1with a mean value of 38.43 kg ha-1. Correlation studies amongst available sulphurnutrients and soil properties pH revealed significant negative correlations between soil pH and available Sulphur. The available Sulphur showed significant positive correlation with EC and organic carbon.
