ABSTRACT
A study on the status and distribution of available sulphur (S) in soils of three selected districts of Chhattisgarh plains was performed during 2013-14. Grid based Soil samples from surface soils of Raipur (198), Durg (210) and Balod (318) were collected using GPS and were analyzed to assess the status of available S and their relationship with some physico-chemical properties. The available sulphur (S) varied from 8.68 to 98.84 kg ha-1 with an average of 40.89 kg ha-1, found 11.11 % samples under low, 12.12 % in medium and 76.76 % in high status of S at Raipur district. Similarly, from Durg district, available S varied from 5.04 to 95.48 kg ha-1 with an average 35.42 kg ha-1 falls under low, medium and high categories as 18.09, 15.23 and 66.66 %, respectively. In Balod district, available S varied from 3.08 to 90.72 kg ha-1 with an average 26.81 kg ha-1 and the percent samples tested under low, medium and high status S were found as 39.30, 24.52 and 36.66 %, respectively. The analyzed data on S level from all three districts were correlated with Soil pH and organic carbon (OC) levels indicated negative correlation with soil pH and positive with OC status. Soil nutrient index of Raipur, Durg and Balod were found in high, high and medium fertility classes for available S, respectively.
