The importance of sulfur for a balanced nutrition of grain crops is demonstrated. The content of mobile forms of sulfur in the main zonal soils of the Kursk region – black soil and gray forest soils is given. Gray wooded soils have a low content of mobile sulfur in most areas of the region. The availability of sulfur in black soil ranges from low to medium. Practical studies on the effectiveness of different types and forms of using sulfur-containing mineral fertilizers in the cultivation of spring wheat on zonal types of soils in the south-western forest steppe of the Central Black Earth Region have been performed. Research has found that the practicability of using sulfur-containing mineral fertilizers and their agronomic effectiveness is directly associated with the content of available forms of sulfur in the arable layer of the soil. It is most effective and reasonable to use sulfur-containing mineral fertilizers in the cultivation of spring wheat on gray wooded soils. The practical data obtained prove the urgency of the use of sulfur-containing fertilizers in technologies for the cultivation of grain crops on soils with inadequate content of available forms of sulfur.
