Abstract: Studies were carried out on soil sulphur status of 50 soil samples from Tianjin areas by Systematic Approach of Soil Nutrent Status which includes routine analysis,sorption study and greenhouse survey and field confirm.Results indicated that 76% of the total soil samples had much higher available sulphur contents than the critical level,24% lower than that.Sorption study showed that there was a great difference in sulphur adsorption among soils and application of fertilizer sulphur adsorption.Greenhouse survey and field experiments ratified that sulphur had became a limiting factor and application of fertilizer sulphur was necessary for further yield increase in some soils.

Key words: Systematic Approach of Soil Nutrient Status, Soil sulphur, Limiting factor
