Abstract

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.

Highlights

In modern technologies of cropping, in order to obtain the highest possible productivity, it is required to fully provide them with the necessary nutrients of nutrition during the growing season
Practical field tests on the effectiveness of the use of sulfur-containing mineral fertilizers were performed on black soil typical in the conditions of Kursk Federal Agricultural Research Center
In accordance with the data of the agrochemical survey (2019), the arable soils of the Kursk region have a different content of macro, meso- and micronutrients

Summary

Introduction

In modern technologies of cropping, in order to obtain the highest possible productivity, it is required to fully provide them with the necessary nutrients of nutrition during the growing season. The research carried out by leading Russian [6] and foreign scientists [7] in recent years demonstrates the increasingly significant role of this nutrient in the development of highly productive agrocenoses and its polyfunctional role in the biological and physiological processes occurring in plants. This indicates that in the technologies of modern highly productive agriculture, the use of sulfurcontaining fertilizers is becoming an obligatory agrotechnical technique
