Abstract
Relevance. According to the conducted studies, it was found that the disadvantages of steppe nature management include water erosion, deflation and other adverse phenomena. Similar processes are taking place in Siberia. At present, the redevelopment of deposits is beginning and soil degradation is again manifested in the steppe regions of Khakassia. For the rational and efficient use of land resources, it is necessary to develop a technology for processing soil deposits in the arid steppe zone of the south of Central Siberia. Methods. The study of the efficiency of soil cultivation technologies for the erosional agroecological group of fallow lands was carried out in the arid steppe agrolandscape region of the Republic of Khakassia, located in the south of Central Siberia. Research for four years was carried out in the link of fodder crop rotation: a long-term (20–25 years) cereal-forb fallow — oats (corn) for green mass by the method of B.A. Dospekhov. When performing the work, statistical and graphical methods were used. Results. It is established that malicious perennial grasses and juvenile weeds grow on long-term fallow lands (20–25 years). High efficiency of complex application of herbicides of continuous action (Tornado 500, Octopus Extra) and intensive tillage was revealed. Tillage of a long-term deposit to a depth of 18–20 cm, disking, fine flatcutting treatment and spraying with herbicide reduces the number of perennial weeds by 2 times more compared to technologies, that include small treatments and herbicide application. In the arid steppe zone, the technology with tillage of a long-term deposit to a depth of 18–20 cm increases the productivity of the feed crop rotation link by an average of 25.3–33.7% compared to technological operations involving small-scale processing (12–14 cm and 14–16 cm).
