Abstract
In a long-term stationary field experiment on soddy–podzolic soil, the effectiveness of organic and mineral fertilizers and their effect on soil properties, yield, and quality of perennial grasses in feed six-field crop rotation was established. It was determined that the combined use of fertilizers most effectively affected the increase in soil fertility and the productivity of the clover-timothy mixture. The content of humus increased by 0.4–0.6%, mobile phosphorus by 70–150 mg/kg, metabolic and hydrolytic acidity decreased. The complex application of fertilizers, especially in high doses, most significantly increased the yield and quality of perennial grasses.
