The research of the rain intensity adaptation to the conditions of hydrophysical characteristics of soil for ecological and economical improvement of the irrigative equipment

Abstract

The article presents the result of the research on the possibility of using in the watering process the effect of swallowing and cracking of chernozem soils depending on their humidity. Watering installations where the rain intensity is variable or constant but higher than Kf = const lead to an essential reduction of working time in position, since in this case the soil soaking process also includes the infiltration phase. Water losses would be less because in this case the soil soaking process also includes the infiltration phase in which, depending on its initial humidity, the soil can incorporate essential water volumes. Consequently, it is possible to improve the ecological and economic efficiency of the irrigation technique by adapting the intensity of the rain to the dynamics of the process of water movement in the soil during the watering process.
