Basic measures to increase soil fertility of agricultural lands of the republic of Belarus for 2021–2025 years

Abstract

The complex of measures to improve the fertility and protect agricultural lands from soil degradation in the Republic of Belarus for 2021-2025 includes measures to optimize the acidity of soils of arable and meadow lands, determine the amount of liming of acidic soils and the need for lime ameliorants to maintain an optimal soil reaction. Measures are given to increase the reserves of organic matter in soils, such as optimizing the ratio of row crops and perennial grasses, determining the need for organic fertilizers to ensure a deficit-free balance of humus in soils. The balance of nitrogen, phosphorus, potassium, sulfur was assessed and the need for mineral fertilizers for 2021-2025 was determined. The system of application of micronutrient fertilizers in the technologies of cultivation of agricultural crops is described and the need for micronutrient fertilizers for foliar feeding of agricultural crops is calculated. The system of measures to protect soil from degradation includes the recommended use of land and the structure of crops on lands with varying degrees of soil erosion, soil treatment, depending on the degree of their erosion and the particular application of fertilizers on eroded soils. The assessment of the effectiveness of measures to improve soil fertility and protect them from degradation has been carried out.
