The effect of cultivation of legumes on the fertility rate of sod-podzolic surface-gleyed soil
has been investigated. Based on the obtained results it has been found that on average,
during the years of cultivation, the fertilizer factor with a percentage of 62% turns out to be
more influential in terms of yield obtained from 1 ha of dry mass. The highest nutrient content
is observed on the alfalfa variant: alkaline hydrolyzed nitrogen-80.4 mg/kg of soil, mobile
phosphorus-81.5 mg/kg of soil and exchangeable potassium-77.3 mg/kg of soil.

In order to preserve and increase soil fertility, as well as to increase agroecological
resistance to adverse anthropogenic factors, it is essential to accumulate organic matter in
the soil. Due to the sharp decrease in the number of livestock in the farms of Ukraine, it is
almost impossible to address this problem only by introducing manure. Therefore, it is
necessary to find ways to restore and maintain the optimal level of soil fertility by means of
the application of alternative methods of accumulation in the soil. One of the main resources …
