FORMATION OF STRUCTURAL-AGGREGATE COMPOSITION AND WATER-PHYSICAL PROPERTIES OF GRAY FOREST SOIL DEPENDING ON MINERAL FERTILIZERS AND LONG-TERM EFFECT OF LIME

Abstract
The article presents the research data of structural-aggregate composition, water-physical constants and density of compilation gray forest coarse-dust–light-loam soil for the systematic use of mineral fertilizers and long-term action (8 th - 10 th year) of chemical melioration. The influence of the long action of a single dose of lime on hydrolytic acidity on the transformation parameters of soil properties was established. The presented results of the use CaCO3 (1,0 Hг), testify to an increase in the quantities of agronomically valuable part of the soil in 3.5 %. At the same time, the volume of adsorbed water by the soil increased and keeping it in the capillary and general space. The shown influence of the systematic use of physiologically acidic mineral fertilizers on the agrophysical and water-physical properties of gray forest soil. Adding N50P30K55 led to increased content of dust fraction of soil and reduce its filtration capacity, which is bad for the soil properties. The use of a single and a double dose of mineral fertilizers intensified the peptization of soil aggregates. Due to this, increased the amount of finely-dispersed parts, which is sedimented and accumulated in the lower layers of the soil. As a result, the filtration ability of the soil and absorbing its properties deteriorated, and the density of the composition during vegetation increased.
