Abstract
The study was conducted in Madurai district with a view to assess the soil available sulphur status at block level. A total of 1724 geo referenced surface soil samples have been manually collected from 13 blocks. The soil samples were analyzed and it is observed that 95and 5 % of the samples of the study area are deficient and sufficient in available sulphur content. The overall results portray that: barring Kottampatti block, the remaining blocks are severely deficient in available sulphur irrespective of the type of cropping systems and hence an intelligent application of sulphur fertilizers and organic manures are right away recommended.
