The role of post-grain residues in increasing soil fertility

The analysis of the condition of the areas post-grain residues. The results of the influence of organic and mineral fertilizers under various irrigation regimes are analyzed. Various fertilizer and watering options were investigated. The qualitative and quantitative composition of the soil was determined. The research results showed that with 3 irrigations during the growing season and fertilizer rates N120P150K150, the largest accumulation of grain residues occurs. Plant residues contribute to an increase in the content of organo-biological substances, as well as improving the water-physical properties of soils and increasing their fertility.
