Abstract

The article is devoted to the analysis of long-term data (1964-2019) and mathematical modeling of the impact of the complex of anti-erosion techniques in fodder and field crop rotations on the elements of water balance and soil erosion on the erosion-prone slope of 4,5°. It is established that after full-scale reclamation of the slope (filling of ravines, planting of contour forest strips reinforced by shafts-ditches) it is necessary to develop lands initially with perennial grasses (perennial rye, alfalfa), and then with crops of field crop rotations with the restriction of the use of tilled crops and fallows to 25 %. Fogger crop rotations re-duce the coefficient of surface runoff compared to the field by an average of 1.83 times, and erosion - 2.26 times. Forest strips together with mulched para-plowing reduce the runoff coefficient on average for crop rotations by 3 times, and erosion - by almost one order of magnitude – to an allowable value of 0.3 t/ha for southern chernozem with A+B < 0.5 m. Modeling has shown that soil erosion is 99 % associated with the runoff coefficient and the degree of protection of ploughed field by agrotechnical and forest improvement techniques in crop rotations. The results of the research can be used in digital mapping of eroded lands in modern precision farming systems implemented in the Saratov region in order to improve the efficiency and quality of their use.
