Abstract
The water stability of the soil structure is one of the most important factors determining its erosion stability. Sod-podzolic soils by their genesis are characterized by low stability to erosion. Therefore, it is relevant to develop agrotechnical and agrochemical techniques that promotes increasing the water stability of aggregates of eroded soils. The novelty of the presented work is a study of the effect of crop rotations with different soil protection capacity, as well as fertilizer systems in crop rotation on the water stability of the structure of eroded sod-podzolic soils to various degrees. It has been established that of the agrophysical and agrochemical properties affecting the structural and aggregate state of soils, the water stability of the soil structure depends mainly on the content of organic matter. The use of eroded soils in grass-grain crop rotations with saturation of perennial legumes up to 75% and the use of an organomineral fertilizer system and liming in crop rotation lead to an improvement in the water stability of the soil structure. It was found that the weighted average diameter of the water-bearing aggregates decreases with an increase in the degree of erosion degradation of soils. Cultivated crops do not have a significant impact on this indicator. There is only a tendency for its increase under alfalfa for the third year of use in the grass-grain crop rotation. There is also no reliable effect of fertilizer systems on the weighted average diameter of soil aggregates. The results obtained are the scientific basis for the development of soilprotective adaptive-landscape farming systems for different agrotechnological groups of lands subject to erosion degradation.
