Необходимые условия качественного дождевания на дерново-подзолистых суглинистых почвах

Abstract

The article presents results of research into the speed of water absorption by sward-podzolic loamy soil. In general, obtained values of Кt, Куст., Кi help to establish regularities of water seepage in the higher layer of soil and limit values of absorption speed. In the first approximation, the established speeds of absorption can be tentatively taken for the admissible speed of sprinkling under the following conditions: soils should be sward-podzolic and loamy; soil moisture should be within 60-80% of the lowest moisture capacity; perennial grasses should be of the first and second year of usage.
