Abstract

                                The available, organic and total sulphur content over the profile depth upto 6 cms were investigated in a long term fertilizer experiment, which was continously cropped for 20 years with a crop rotation of finger millet-maize-cowpea. The available S increased from surface (0-15 cms) to sub surface soil (15-30 cms) and again decreased at 30-45 cms and the content was almost the same at 45-60 cms also. The same trend was seen in the case of organic S. But, the total sulphur content was found to decrease from 0-15 cms to 45-60 cms depth.

Key words : Long term fertilization, available S, organic S, total S.
