Plant and Soil Science

The article presents the results of studies of soil indicators and evaluation the parameters of their environmental sustainability. It has been established that the agricultural use of soil has led to manifestations of agrophysical degradation. It was noticed the high lumpiness above 28.9%, the soil silt content as 7.62% and bulk density was high 1.44–1.47 g/cm3. Trends in the manifestation of dehumification of agricultural soils due directly or indirectly to their intensive agricultural use are revealed. The humus content of dark gray soil in the cultivated fields after soybean harvest was 2.89 ± 0.11%, on the similar soil under the forest stripe – 3.75 ± 0.05%. Reduction of degradation processes can be achieved by introducing into the rotation of perennial grasses, which will improve its structure and organic matter content. To suspend dehumification, it is necessary to increase the proportion of organic fertilizers and to maximize the use of by-products of crops.
