Abstract: 420 soil samples which represent different cultivated soils were analysed the contents offast-acting sulfur.The sulfur content in the samples form plain area was higher than that from hilly area, and coastal area was higher than inland area.The average content in whole province is higher than the cultivated one required for the growth of main crops such as rice plant.The stress areas for supplying sulfur are submerged and sandysoils.It also needs to pay more attention on applying S fertilizer to economical and mustard crops.The application of sulfur improves the early growth and development ofrice seedlings.increases grain number per panicle thus enhance the grain yield.S application to legume plants increases its biomass production and improves quality.
