INFLUENCE OF PROTECTIVE FOREST PLANTS ON SOIL FERTILITY IN AGRARIAN LANDSCAPES (ON THE EXAMPLE OF THE PISKAREV PEASANT HOUSEHOLD OF PAVLODAR)

Abstract

An important point of conservation and restoration of soil fertility is the stopping of erosion processes. The increase in soil fertility is the most important factor in the formation of high yields of agricultural crops. Expanded reproduction of soil fertility is possible only when using scientifically based ecological and landscape systems in agriculture, balanced, compensatory nature of land use.
To preserve and reproduce the fertility of agricultural land, it is recommended to systematically apply mineral and organic fertilizers to maintain soil fertility in the optimal regime: some of the nutrients alienated with the harvest must necessarily be returned to the soil with fertilizers. The use of fertilizers in the fields showed their high efficiency, both in agrarian and forest landscapes by 1,1-1,4 times. Moreover, when fertilizers are added into the soil (containing nitrogen, phosphorus and sulfur), the yield of agricultural crops is increased by 1.4 times. In the process of research held in the Piskarev peasant household in 2015- 2017 on degraded soils of agricultural use of Pavlodar region, the positive role of protective forest belts on the accumulation of moisture and preservation of soil fertility was revealed. Investigations involving the study of the influence of protective forest plantations on the conservation and improvement of soil fertility make it possible to address the issues of environmental protection, conservation and reproduction of the fertility of degraded soils in Pavlodar region.
