Abstract
Precise field experiments were established at 3 sites with oilseed rape under different soil-climatic conditions in the Czech Republic (Humpolec, Hněvčeves and Uhříněves) in the years 2008-2010. In this experiment, four fertilizing treatments with increasing S rate were evaluated. The contents of bioavailable (SW), adsorbed (Sads), occluded (Socl), and hydroiodic acid (HI) reducible (SHI) sulfur were measured. The contents of the fractions within the studied sites in the samples collected before fertilizers application were comparable. The SW, Sads a Socl contents did not exceed 10 mg S/kg. The SHI contents differed depending on site and year. Fertilizing using S as CaSO4 positively influenced the contents of SW, Sads, and SHI in soil. Sulfur fertilizing had also the positive tendencies to increase the winter rape yields but the differences between studied treatments were not statistically significant.
