Soil samples from varying depths and plant samples of wheat at the same sites at maximum tillering, flag leaf and at maturity stages were collected from 22 fields in order to study the relationship between the distribution of available S (0.15% CaCl2 extractable) in soil profiles and the S nutrition of wheat crop. The profile distribution of available S generally did not follow any specific pattern, barring 6 profiles, whereas the content showed a regular decline with depth. Surface soils, by and large, were richer in available S than in the lower layers. Total S concentration in plants was highest at maximum tillering stage and it showed a decrease with the advancement in age of the crop.
