CURRENT STATE AND EFFICIENCY OF BLACK LEACHED SOILS OF WESTERN CAUCASUS

abstract 1531909005 issue 153 pp. 52 – 65 29.11.2019 ru 19
The article studies current state of fertility and productivity of leached chernozem used in the 11-field grain-grass-row crop rotation. Under the conditions of a stationary field experiment, a soil section was laid, a morphological description of the soil was carried out, its magnetic susceptibility χ was measured, soil samples were selected from soil-genetic horizons, in which the particle size distribution, physical and chemical parameters were determined. Studies have shown that leached chernozem is characterized by an addition density of 1.30 g/cm3, a solid phase density of 2.67 g/cm3, a total porosity of 51.9 %, χ = 1,045 × 10-3 units SI, pHwat. 6.5 units, humus content 3.2 %, its stock in the layer A + B = 468.2 t/ha, the sum of the exchange Ca2+ and Mg2+ 42.8 mg.eq./100 g. The use of mineral fertilizers increases the productivity of leached chernozem: the yield of sunflower of 11-field grain-grass-row cultivated crop rotation exceeds the control without fertilizers by 1.02-1.62 t/ha

INFLUENCE OF THE MELIORATIVE CONDITION ON THE PROPERTIES OF SOILS OF DRAIN AGROLANDSCAPES OF KUBAN AND THEIR PRODUCTIVITY

abstract 1321708017 issue 132 pp. 218 – 230 31.10.2017 ru 126
In the soils of rice fields, eluvial gley processes develop, which are manifested in redistribution of silty particles along the profile, water-soluble humus, mobile compounds of iron and phosphorus. Most intensively, these processes are developed in meadowbog soils, confined to closed depressions of the plains plain. Meadow-black soils lying on elevated relief elements have more favorable physical, physicochemical and oxidation-reduction properties for cultivating rice and accompanying crops in crop rotation. The highest yield of rice is formed on high checks and higher at 12,4 c/ha than on low ones
