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 chara ...

This review contains the information about the role of annelids in maintaining soil fertility. Recommendations based on authors’ experience and scientific literature are given for vermicultivation, biomass use of Californian worms in animal husbandry and vermicompost use in crop production. Furthermore, detailed description of the methods of cultivation of worms is given

The description of the 2-layers, substrates at KMA dumps after covering it with a black soil layer is given. It has been concluded, that this method of substrates fertility increasing is not suitable for a forest recultivation

Grapes are product of areas. Grape plant is very plastic and can grow on almost all types of soils except highly saline, fusion and wetlands. In studies of many authors, it was indicated the influence of different soil types and their properties on the growth of the vine plants, the quality of berries and their products. The object of study is soils and vines growing on them, laws and processe ...

Lukyanenko Krasnodar Agricultural Research Institute. Stationary experience was founded in 1978. It had two ten-course crop rotations and combined graingrass tilled. The ordinary black soil, low-humic, heavy loamy in mechanical compos ...

The article deals with the effectiveness of mineral and organic fertilizers in long-term application (for more than thirty years) according to the influence on the fertility of ordinary black soil of the Western Ciscaucasia and productivity of sugar beet. The investigations were carried out in the long-term stationary experiment laid on the experimental stationary section "Severokubanskaya agr ...

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 fer ...

The article gives a general assessment for meliorative state of soils at the rice irrigation systems in the Ros-tov region. The indices of soil salinity, alkalinity, sodicity, calium content in soil exchangeable com-plex of dark chestnut soils at different crop rotations and water loadings are afforded

The article discusses the various technologies of cultivation of winter barley at two ways of main tillage (recommended and zero-level) with different backgrounds of soil fertility, fertilization rates, protection from weeds, pests and diseases. Consistent improvement of soil fertility and other fertilizers resulted in an increase in crop productivity. Nutrition is the basis of life of a livin ...
