Increasing the stock of organic substance in soils agricultural lands of the Republic of Belarus

Abstract

The article presents an analysis of the dynamics of organic matter in soils and the distribution of soils of arable and meadow lands by humus content groups according to the latest data of the large-scale agrochemical survey of soils of the republic (2015– 2018). In order to increase the reserves of organic matter, optimal ratios of row crops and perennial grasses in the structure of sown areas are proposed, the need for organic fertilizers is determined and the calculation of possible volumes of production of organic fertilizers and other sources to ensure a deficiency-free balance of humus in the soils of arable lands is given. In the process of applying organic fertilizers, technological aspects of increasing the efficiency of their use are presented.
