THE RESEARCHES IN THE FLOODPLAIN OF THE STEEPE ZONE OF THE KRASNODAR REGION
DescriptionThe article presents the violation of water protection zones. The change in soil fertility. Transparency is linked to the nature of the coating beaches and surface destruction. Surface runoff depends on the vegetation cover. The destruction of vegetation (deforestation, excessive grazing, fire), incorrect plowing surface (along the slope) and tillage farming without following the rules lead to increased erosion, local soil erosion, gully erosion and the rise to an increase in turbidity of rivers. Environmental effectiveness of forest plantations. Prevention of pollution and siltation of river. Improving the sanitary condition of the territory

Description
Residual amounts of pesticides in the coastal water of the Azov Sea were studied in the spring seasons of 2009–2011. The concentrations of the pollutants were determined and the degree of their danger for hydrobionts was assessed. The concentrations of pesticides diluted in the water of the Taganrog Bay and the eastern Azov Sea are shown to be lower than the maximum admissible concentrations set for fishery ponds

INVESTIGATION OF TRACE ELEMENT COMPOSITION OF RAW STEVIA REBAUDIANA BERTONI MATERIALS
DescriptionThe article gives an analysis of the elemental composition in raw materials of stevia. Stevia plant is able to regulate the flow of heavy metals, allowing them, on the one hand, actively oppose the excessive intake of toxic elements and on the other hand, selectively cumulate essential elements. The contents of essential elements in plant raw materials do not exceed the acceptable standards regardless of the growing conditions

Description
The research of the territory adjacent to Novocherkassk state district power station, for the content of polycyclic aromatic hydrocarbons (on an example of benzo(a)pyrene) is presented. The benzo(a)pyrene content in soils has been determined with a method of subcritical water extraction. The content of benzo(a)pyrene in soils of the territory adjacent to Novocherkassk state district power station has been estimated. It is shown, that contents of benzo(a)pyrene excess over maximum permissible concentration in soils of five-kilometer zone around the companies

USE OF EPIN-EXTRA, R PREPARATION ON SEED PLANTS OF ONION
DescriptionAn important element in the technology of growing seed plants of onion is the use of physiologically active substances to protect plants from frost in early spring growing season. Damage to plants during this period affects seed production. In the experiment we used preparation called Epin-Extra R, with which the leaves of plants were treated a day before expected frost. Test results have shown high efficiency of preparation in the field and in the film unheated greenhouse. Treatment helps to balance the negative impact of low temperatures and obtain an additional seeds yield 92-95 kg / ha more compared with the control, due to the increase of seed of productivity of plants to 3.2 g
