This article describes how the periodic flooding of soil on a sandy soil model. It was established, that during the lateral movement of moistening of the soil, the moisture has a form of damped oscillations

The modern level of cultivation of agricultural animals requires new approaches to the processing and disposal of manure. To do this, it is necessary to develop effective ways of converting waste into organic fertilizers, which, in the form of liquid effluents, make it possible to enhance and preserve the soil fertility of agricultural landscapes. This is especially necessary to be carried out on black soils, where irrigation of crops with prepared and diluted drains has a positive effect on the harvest. Therefore, the creation of manure processing systems by technological sequentially related operations is an urgent problem. Cattle manure is considered as a poly-dispersed system with sedimentation and physical and chemical properties. In this case, the system requires the sequential solution of a number of complex tasks: removal of various inclusions from manure, especially colloidal and fibrous particles; prevention of premature separation of manure during homogenization; preparation of manure for separation into liquid and solid fractions is a basic technological scheme that is universal and applicable to all types of livestock-raising complexes. A feature of the integrated cattle manure disposal line is a lagoon for year-round storage of a certain amount of manure drains prepared for irrigation during the growing season. For the creation of the lagoon, a film coating is used - it works as an anti-filtration screen
