Over 1991-1994, the effects of graduated doses of NPK, sulphur and liming on changes in the content of sulphate sulphur, heat-soluble sulphur and post-burning soluble sulphur were investigated during winter wheat vegetation period using methods as described by Wiliams and Steinbergs. Winter wheat variety Kosutka was chosen for the experiment carried out under the conditions of stationary field fertilization trials using loamy brown soil on bess. It was found that in the soil depth of 0 to 0.3 m, sulphate sulphur amounted to 11.03%, heat-soluble sulphur to 30.86%, and post-burning soluble sulphur to 68.91%. In the soil depth from 0.3 to 0.6 m, the content of sulphate sulphur was higher whereas that of heat-soluble and post-burning soluble sulphur was lower. NPK fertilization increased the sulphate sulphur content in soil. The latter decreased during winter wheat vegetation, which confirms the fact that this fraction of sulphur is a++ source of sulphur for plants
