EFFECTIVENESS OF DIATOMITE OF KAMYSHLOVSK DEPOSIT OF SVERDLOVSK REGION AT CULTIVATION OF BEETROOT
The article focuses on the role of silica and its compounds in soil processes, their impact on growth and development of plants beet. Minerals of silicon are considered as a source of soluble silica, which plays an important role in the formation of soil fertility, enhancing the productivity of plants and their resistance to disease and pests. In turn, silicon plays a large role in the metabolism of plants, will cease their skeletal part positively affects the strength of the plantlet component. In the article were given that the balance of silicon in agrosystem always negative, for the filling to make flint fertilizers. Among them are promising natural source of available silicon is high concentrated silicon-content breed-diatomaceous earth deposits, Kamyshlovsk produced in the Sverdlovsk region on an industrial scale. The objective of our research was studying the effect of diatomite deposits of Sverdlovsk region Kamyshlovsk on growth, development and yield of beets. Options for excellence: mineral fertilizers (N 90P 90K 90) - background; background + diatomaceous earth in a dose of 2.0 t/ha; background + diatomaceous earth in a dose of 4 t/ha. By results of researches it is established that the application of diatomite as fertilizer in the cultivation of beet in the Middle Urals the beet yield 4.6-6.6 t/ha or 13-19 %, marketability of products, a lot of the standard root crop and yield of by-products.
