| Popis: | Intensification of agriculture in the forest-steppe zone of the Middle Volga region requires solving the problem of preserving the soil and its potential and effective fertility in order to increase crop productivity and quality of crop production. In this regard, the development and implementation in agricultural practice of agrobiological techniques to prevent anthropogenic degradation in agricultural landscapes is an urgent direction of modern agricultural science. The purpose of the research was to compare the effect of the implementation of manure, green manure and their combinations with the stover biodestructor on the physical and chemical properties of meadow-chernozemic soil. To reach this purpose, research was conducted in the period from 2017 to 2019 in the first agro-soil district of the Penza region. Research has shown that the effect and after-effect of manure, green manure and their compound action and after-action with the stover biodestructor had a positive effect on the physical and chemical properties of meadow-chernozemic soil. Green manure fallows were not inferior to manured fallows in terms of their effect on the cation-exchange capacity, the sum of exchange bases, and the amount of exchange and hydrolytic acidity. A compound action and after-action of manure, the oil radish and green manure of legumes with the stover biodestructor had a more significant influence on the change in the physical and chemical properties of the soil. In their background, the cation-exchange capacity increased by 1.40-1.51 mg equivalent/100 g of soil, the sum of exchange bases by 1.6-1.7 mg equivalent/100 g of soil, the value of рНКСl 0.22-0.24 units, the value of hydrolytic acidity decreased by 0.17-0.19 mg equivalent/100 g of soil. |
