Form and parameters of drip irrigation of soils on slope lands

Abstract

Studies of local moisture contours were carried out on landscape formations with surface slopes of 0, 3, 5, 6, 7, and 9 °, the soil cover of which is represented by medium southern chernozems. As a result of the analysis, the facts of the local asymmetric moisture contours formation on the slope lands with an excess of the boundary surface in the slope direction and along-slope of the contour axis displacement have been found. In the process of experimental material processing the experimental dependences that make it possible to evaluate the influence of the slopes steepness on the contour geometric parameters are established. A generalization of the experimental material and well-known recommendations for determining the local moisture contours parameters made it possible to develop a methodology for predicting the shape of drip moistening contours in soils formed on slope lands.
