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 ...

black soil; microwave radiation; oil; pollution; combined action; lead

In the model experiments we studied the effect of combined action of chemical pollutants (PbO 1,000 mg / kg oil 5% by weight of soil) and microwave radiation (SHF radiation) with a capacity of 450 and 800 W (duration 1 minute) on the enzymatic activity, the number of microorganisms and indicators of phytotoxicity of an ordinary black soil. We found that the combined effect is systemic, rather ...

Five-year data of the influence of direct affect and the post action of decomposed turkey droppings on the sunflower husk on crop productivity in three-level field crop rotation of spring barley - sunflower -spring barley and in a comparison of its action with the effect of fertilizers on crop yields were presented in the article. The affect of the droppings exceeded affect of mineral fertiliz ...

About 40 soil cuts were made in various parts of the city of Rostov-on-Don. The determinations of enzyme activity (catalase, invertase, polyphenoloxidase) were carried out in natural and antropogenic soils of a sub-urban park, residential and industrial areas of the city. The enzyme activity of soils in urban condition signif-icantly lowers than in non-urban soils. It is established, that sign ...

pollution; land reclamation; biopreparation; soil; black mineral oil; water

Oil products are among the most widespread pollutants of objects of environment. Near Maikop in 2008 the large center of black oil pollution was formed. This site became the range for studying of consequences of black oil pollution of soils and water objects under natural conditions. In the real work stages of a recultivation of the soils polluted by fuel oil on a site in Maikop are described. ...

The article presents three-year data on the influence of different fertilization systems and predecessors (corn for silage and peas) of winter wheat in the rotation on the dynamics of content in the 0-20 cm layer of black leached soil of mineral nitrogen, of available phosphorus, of potassium, and yield of winter wheat. The materials presented in this article indicate that, regardless of its p ...
