Evaluation of the influence of anti-erosion relief in the inter-row crop spacing on soil washout

The implementation of antierosion measures is an important component of row crop cultivation technologies, especially on sloping lands. To combat water erosion, the study proposes using a device for cultivatorsplant feeders, containing a horizontal shaft with two mirror symmetrically fixed impellers, the use of which will allow to form an antierosion relief between the rows simultaneously with cultivation. The purpose of the presented study is to evaluate the effect of antierosion relief in interrow crop spacing in combination with the magnitude of the slope of the field surface and the intensity of rain on the level of soil washout. The study was carried out using methods for implementing factorial experiments on a laboratory setup. The analysis of the data obtained shows that the most significant of the studied factors is the measure of the slope angle, its increase from 10 to 30 led to an increase in soil erosion from 45 to 150 grams, which confirms the assumption about the danger (in terms of the development of erosion processes) of the cultivation of row crops on sloping lands. The intensity of sprinkler irrigation is the second most important factor that directly affects soil erosion. The depth of the holes formed by the developed device does not significantly affect the intensity of soil erosion. Moreover, at a high intensity of sprinkler irrigation (Q ≥ 5,0 l/min), its increase leads to a slight increase in the intensity of soil washout, and, on the contrary, at Q function show_eabstract() { $('#eabstract1').hide(); $('#eabstract2').show(); $('#eabstract_expand').hide(); }
