In work characteristics of the mixing device of new type and principles of its work are given. The geometry of liquid, stream has been ivestigated arising in a tank when operating. Offers of rationalization character were brought.

To improve soil water regime and moisture supply of plants, moisture-swelling polymeric materials are used in the form of hydrogels, which, upon contact with water, rapidly absorb and retain it for a long time in its volume. However, widespread of such hydrogels used in plant growing is currently limited by its high cost. In this connection, from the economic point of view, the use of composite materials as soil conditioners is of great importance, including inexpensive natural raw materials in its composition while maintaining high rates of moisture sorption and water retention. The task is to improve the mixture to maintain the soil balance of various agricultural crops by changing the quantitative ratio of components, significantly cheaper the composition, improving its quality indicators. The purpose of the scientific article is the mixture for maintaining the soil balance of various agricultural crops, which contains an active product based on a granulated hydrogel and a targeted additive.
