During five rotations of a ten-field crop rotation in a stationary field experiment, the influence of annual application of fertilizers on productivity and quality of sunflower seeds (Helianthus annuus L.) was studied. The dynamics of the nutrient re

Meadow chernozemic soil was studied in an idle land-shelterbelt-cropland system. It was found that the long-term agricultural use of chernozems leads to a decrease in the total nitrogen content and to changes in the soil microbial community. The port
