| Summary: | The article shows the results of three-year field experiments to study the effect of different dos-es of chicken manure and lime ameliorant on the physicochemical properties of leached chernozem and the yield of cultivated crops in the experimental plots. The studies were carried out on the exper-imental field of Penza State Agrarian University (Penza Region, Mokshansky District). As a result of, it was revealed that when different doses of chicken manure were applied, an aftereffect increase in acidity was observed in the second and third years. The use of a lime ameliorant reduces acidification and increases the effectiveness of the applied doses of chicken manure. The use of doses of chick-en manure from 2 to 10 t/ha (dry matter) had a positive effect on the grain yield of both the first crop after application, and the second and third. The highest productivity of the studied crops was ob-served in the variants with the introduction of 6 to 10 t/ha of manure. Against the background of lim-ing, the effectiveness of their application increased. |
