CHANGES IN TRACE ELEMENTS AND ABSORBED CATIONS IN SALT MARSHES AND IRRIGATED MEADOW SAZ SOILS.

The dependence of the content and composition of the absorbed base on the degree of soil cultivation is presented. It is shown that, starting from virgin salt marshes, there is an increase in the absorption capacity of soils in the direction of monoculture - without fertilizers → monoculture + NPK → monoculture + NPK + 10 t / ha of organic fertilizers. Simultaneously, in the soil absorbing complex, indicated direction.
