INFLUENCE OF STRUCTURE MELIORANTS ON THE ACID-ALKALI BUFFERING OF THE PODZOLIC SOILS OF THE LIGHT TEXTURE

Abstract

In the article presented the results of research of the effect of structure melioration on the acid-alkali buffering of podzolic soils of light texture (loamy sandy and cohesive soil). For research (as structural meliorants) chose: clay, loess, peat. The meliorants introduced in two ways: sprawling and locally into the subsoil layer to a depth of 25-30 cm. Has been proved that structural cultivation of podzolic soils with light texture should be considered as an effective way to improve their agroecologi state, as evidenced by indications of acid-base buffer properties of soils. It has been established that the introduction of loess at a rate of 3 t/ha locally into the podzolic soil contributes not only to an increase in pH in local zones, which is very important for soils with acidic reaction of the medium, but also increases the acid-base buffering in general. The cultivation of podzolic soils of light granulometric composition by applying clay, clay together with peat, both locally and spontaneously, is an effective factor in improving their agroecologi status.
