Available sulphur status in cultivated soils of Aravalli district of North Gujarat

Abstract

In order to assess the available sulphur content in soils of Aravalli district of North Gujarat, two hundred and sixty five surface soil samples (0-15 cm) were randomly collected from 6 talukas of Aravalli district of North Gujarat. All the collected soil samples were analyzed for available sulphur as per standard procedure. Results revealed that the available S content in soils of Aravalli district varied from 3.64 to 86.91 mg kg-1 with a mean value of 24.21 mg kg-1. Out of 265 soil samples of the district, 20.38, 31.70 and 47.92 per cent were found under low, medium and high category for available sulphur, respectively. According to the nutrient index value (NIV), soils of Aravalli district were adequate in available sulphur (2.28). Significant positive correlation was found to exist between organic carbon and available S status of soil under study.
