Pot experiment on 3 crops (wheat, corn, oilseed rape) and a pasture (clover) under 5 levels (0, 5, 10, 20, 40 mgcntdotkg-1) of sulfur (S) was carried out to study S application on yield production, S contents and their relationship of these crops. The results showed that under S application, the biomass of four plants increased by 5apprx32%, and the grain yield increased by 3apprx20%. The contents of S varied with different corps, for example, the content of S in the oilseed rape was the highest (0.479apprx1.228%), and that in corn was the lowest (only 0.043apprx0.091%). The contents of S in different plant parts of the same crop had a positive correlation with content of S application. Both the biomass and grain yield for all the crops except the clover had a close correlation with the content of S application. With available S in the soils increased, the amount of S absorbed by crops was increased at the beginning, and then decreased after reached the peak.
