06.00.00 Agricultural sciences
Description
A stationary experiment at Agrochemistry chair of Kuban' state agrarian university has revealed certain changes in humus contents and physical and chemical properties of black leached soil after two stages of field crop rotation as a result of long-term application of mineral fertilizers

Description
Data on influence of macro fertilizers on dynamics of content of more deficit elements of mineral nutrition in leached chernozem on sowings of soy-beans in conditions of perennial stationary experience of the chair of agrochemisrty are casted in the article. Content of ammonium nitrogen in soil depends in great extent on nitric and phosphoric fertilizers. Content of nitric nitrogen is higher than ammonium one. High coefficients of correlation (R=0,822 0,912) speak about authentic effectiveness of applied fertilizers in the rate N60P120K20 ; N60P120 K60. Content of movable phosphates in soil under application of duplex and triplicate rates of phosphor fertilizers separately and in combination with nitric and potassic fertilizers is increased. Potassic fertilizers determine soil enrichment with metabolic potassium among three applied macro fertilizers.

Description
The article shows results of using a mineral fertilizer system on the conditions of the mineral nutrition of winter wheat grown on leached chernozem in 11-field grain-tilled crop rotation conditions of stationary experience. We have also shown the effect of various norms and types of fertilizers on grain yield. Grain increase as a result of using N40 and N40Р30К20 ranged from 0.54-0.50 t / ha, average and elevated rates increased the yield of winter wheat by 0.97 and 1.03 t / ha, which is higher than the control by 17.1 and 18 , 2%

SOIL AND LEACHED BLACK SOIL ENVIRONMENTAL EVALUATION OF WEST CAUCASUS
06.00.00 Agricultural sciences
Description
The analysis of foreign and domestic methods to evaluate soil productivity sowings has been presented. It has shown the need for soil environmental assessment in the West Central Caucasus. The soil-environmental index and index scores for an experimental field of individual crops rotation, which will promptly assess the fertility of the soil, give recommendations for rational allocation of fertilizer has been given

Description
Great practical and theoretical interest comes with a study of the transformation of calcium agrobiogeochemical in agro-ecosystems. The basis of the stability of the soil, as an element of the structure and functioning of the biosphere, constitutes historically approved biochemical cycles and flows of matter and energy, which remain unchanged under anthropogenic impact. Comparative analysis of the total content of calcium leached black soil allowed us to establish its decline after three rotations of grain and grass-tilled crop rotation. Without the use of fertilizers its reduction from baseline was 5.25% in the layer 0-20 cm and 3.87% in the 20-40 cm layer, with their introduction - 9.14 and 9.35%, respectively. This trend suggests a decrease in calcium reserves in the root zone of leached black soil in its agricultural use; this process is more active when using mineral fertilizers. This is obviously due to a large outflow of elements in the fertilizer background with harvest crops, and partly due to the influence of mineral fertilizers as chemical reagents on mineral soils, resulting in the release of calcium and moving it into the lower soil horizons. Along with the total content of calcium and its forms, we have analyzed the activity of calcium ions and calcium potential

Description
The article presents the results of the study on the magnesium mode of leached chernozem of Western Ciscaucasia at three rotation of grain-grass-tilled crop rotation. Magnesium in the soil is represented mainly by non-exchangeable form, the number of which is estimated at 90,18 and 91,29 % of gross reserves. Exchange forms of magnesium are 8,68 and 7,71 % respectively in arable and the subsurface layer. The share of water-soluble and organic forms account for less than 1 % - of 0.62 and 0.68 and 0.46 and 0.38% respectively. For three rotation 11-full rotation of gross stocks of magnesium in the soil in which crops were grown without fertilizers has decreased by 0.02 % (200 mg/kg), with fertilizers of 0.03 and 0.02 % (300 and 200 mg/kg). Intense magnesium has been leached from the topsoil. There was a change of the soil content of the forms of magnesium. In the rotation without fertilizer, the share of non-exchangeable magnesium in the General Fund item increased from baseline by 0.27 % in arable and 0.11% of the subsurface layer of soil that the absolute content decreased. The amount of water-soluble, exchangeable and organic magnesium of the soil decreased. Reducing the amount of water-soluble (0.05 and 0.06 %) and metabolic (0.18 and 0.02 %) of magnesium was due to its consumption of the plants. The proportion of magnesium organic part of the soil is reduced as a result of steadily declining yields, and, therefore, the amount of organic residues. In crop rotation, use of mineral fertilizers we have observed different behavior of magnesium compounds in the soil. The number of non-exchangeable magnesium decreased from baseline by 0.13 % in arable and 0,58 % of the subsurface layer of soil. The content of the exchange of magnesium increased respectively 0.43 and 0.41 %, water soluble - 0.13 and 0.10 %, and the organic part of the soil - 0.02 and 0.02 %

DESCRIPTION OF CERTAIN ASPECTS OF FERTILITY OF BLACK LEACHED SOIL OF WESTERN CISCAUCASIA
06.00.00 Agricultural sciences
Description
The article contains the results of the researches on the experimental field in the "Kuban" educational farm of Kuban State Agrarian University. In the black leached soil we defined particle size, the structure and the composition of water-physical properties of the soil, which are the most important conditions for high and stable crop productivity. We also gave morphological and genetic characteristics of the soil
