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 ...

In the article, we have made an attempt to develop and calculate a model of humus content estimation in the black leached soil according to remote sensing of the ground. We have presented the model which has a number of restrictions for its continuous use when carrying out soil environmental monitoring of land grounds. It is established, that for calculation of similar model it is necessary to ...

The structural and functional properties of humic acids of different types of poorly studied soils of the Krasnodar Region: ordinary black soil or chernozem (carbonated), meadowish chernozem and gray forest soils are investigated. We define the type of humus of the soil samples studied as fulvate-humate. Using traditional indicators of humus soil conditions the regularities of soil and ecologi ...

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 ...

In this article the influence of agrotechnologies of cultivation of field cultures on soil indicators and distribu-tion of heavy metals on the horizons of the black leached soil is considered. Regularities of distribution of gross and mobile forms of manganese, zinc, lead, cobalt, copper and cadmium on the genetic horizons of the black leached soil of the Azov-Kuban lowland are revealed

Hydrothermal conditions have a significant effect on catalase activity of soils of the South of Russia. The linear dependence of catalase activity in the upper horizons soils from average annual rainfall, aridity index of de Martonne and the coefficient of moisture of Mezentseva. In terms of catalase activity of the entire humus profile we revealed that the maximum activity has leached black s ...
