Influence of the long irrigation by livestock drains on properties of the soil

В статье приведены результаты исследований по влиянию дождевания стоками животноводческих комплексов на свойства дерново-подзолистой почвы. Экспериментально обоснована необходимость проведения на орошаемых землях специальной агромелиоративной обработки и периодичность ее проведения.

إنجليزي. In course of the research there was studied influence of overhead irrigation by drains of livestock complexes on properties of the cespitose and podsolic soil. Need of carrying out on irrigated lands of special agromeliorative processing and frequency of its carrying out was experimentally proved. As a result of realized research on a specialized irrigation system &#039

in Orsha district of the Republic of Belarus there were revealed that the use of wastewater of pig complex for fertigation on background of agronomical amelioration contributed to structure formation of topsoil. So when dry sieving agronomically valuable aggregates content in topsoil (0-20 cm) in the control was 72.9%, and at entering drains on background endorheic drainage, their number increased to 76.8%. Irrigation using livestock waste led to compaction of the upper soil layers. In the arable layer of 0-20 cm bulk density compared to the control increased from 1.26 to 1, 32 g/square cm. In embodiments with improvement actions seal was less. Thus, in the 0-40 cm soil layer was greater degree of decompression only in versions with pan busting, loosening and making straw.
