Evaluation of Release Pattern and Availability of Sulphur from Different Sulphur Sources at Different Interval in Vertisol

The experiment was conducted in pot conditions at the Department of Agricultural Chemistry and Soil Science, College of Agriculture, Parbhani from 12 October 2005 to 3 January 2006, in order to study release the pattern of water soluble sulphate sulphur through different sulphur sources at periodic intervals in vertisols. In the incubation study, the water soluble sulphate sulphur was increased due to addition of various sources of sulphur. Water soluble sulphate sulphur increased upto 56 days in Vertisols and gradually decreased there after. Out of four sources tried S-90 (T₁) released water soluble sulphate sulphur to the maximum followed by SSP, gypsum and elemental sulphur.
