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

APOGEOTROPIC SHOOTS OF CEREALS
DescriptionApogeotropic shoots of cereal different of wide range of types of shoots, noticeable differences on characteristic, features of development, their role in the herbage, the seasonal dynamics of crop formation, experiencing noticeable effect on the reaction conditions of soil fertility and humidity. Multiyear cereals in the process of shoot formation form the generative, hidden generative, elongated, short side and underground runners. Multiyear cereals are widely distributed throughout the world, including the tribe Antropogoneae, Chloridaeae, Maydae, Peniceae, Tripsaceae, Festucoideae and others that presented in different parts of the world, and perennial and annual forms. Many cereals are allocated notable longevity, which is largely determined by a wide adaptability to vegetatively propagate. Between northern and southern grasses differences are observed throughout the development of individuals, beginning with emergence. In the southern cereal first sheet has a lancet or ovoid shape and bent at a right angle to his vagina, it is the northern linear subulate form. Cereals are different typology of different shoots. Most large divergence is characterized with erect shoots in both groups of cereals

FEATURES OF MINERAL WASTE AND THE EXPEDIENCY OF THEIR USE IN THE FOR-MATION OF COMPLEX COMPOSTS
DescriptionThis article summarizes the results of the study of physical, chemical and biological characteristics of mineral waste; it analyzes the specific features of its behavior when applied to the soil in pure form and in complex compost; the possibility of using some of them as an ameliorant for improving the fertility of soil common in the steppe zone of the region

DEVELOPMENT OF PROTEIN ENZYME FEED ADDITIVE FOR POULTRY FARMING
DescriptionThe research work was conducted at the Research Laboratory of Biotechnology, Biochemistry, Biophysics Department of Kuban State Agrarian University. The main purpose of this study was to select the most productive type of fungus of a genus of Trichoderma and optimal nutrient medium on basis of a waste of reprocessing of soy for acquire of protein enzyme feed supplement. For selection of a fungus of a genus Trichoderma used 3 types: Trichoderma viride, Trichoderma lignorum, and Trichoderma harsianum. We used 3 types of nutrient media as a carrier for micromycete, which were based on soy okara and the additional sources of reprocessing of raw plant material – husk of a sunflower, husk of wheat (bran) and husk of rice. The results demonstrated the benefits of using the nutrient medium based on soy okara forms and husk of a sunflower fungus to enhance Trichoderma lignorum production

60 YEARS IN THE RANKS: FEATURES OF MOLECULAR BIOLOGY OF BEZOSTAYA 1 WINTER WHEAT VARIETY
DescriptionThis review is devoted to the 60 anniversary of the winter wheat variety (Triticum aestivum L.) Bezostaya 1 – a masterpiece of world selection. This variety played a great role in increasing total grain yields in the Kuban Region. It also was an important gene source for Russian and world breeding. This variety has initiated and was for many years a party to research molecular biological mechanisms of wheat frost resistance formation. The article summarizes data about the peculiarities of functioning of protein-synthesizing system it sprouts (coleoptilies) under the influence of hardening temperature (4oC): translational activity in vitro, poliribosomts, degree of polyadenilation and stability of total mRNA and specific mRNA translational elongation factor α subunit 1 (eEF-1 α). The in vitro (ommp) system, which adequately characterizes the relative mRNA stability in vivo was used for these measurements. The effects of cooling and light on mRNA stability were shown to be cultivar-specific. The hardiness of winter wheat has a positive relationship with the amount of RNA and DNA, and a negative correlation with the amount of magnesium cations in mature grain that can serve as a simple marker of frost resistance. The main feature of the variety Bezostaya 1 is high content of magnesium ions (Mg++) in RNA molecules and relatively low variation of Mg++-depending molecularphysiological responses for different environmental conditions. The knowledge gained in the study of variety of Bezostaya 1 contributes to the understanding of molecular biological processes that underlie the selection and determining its future success

Description
The article presents the ecological characteristics of soil types and forest cover of the Red October forestry of the State Unitary Enterprise of the Republic of Adygea. We have defined their relationship and the division into groups of forestry and environmental values. A complex combination of bioclimatic factors, parent rocks and topography has led to a large diversity of soil cover. We have revealed that different soils have different degrees of erosion on sloping hillsides, ravines, and steep slopes are dominated by strongly eroded soils. The most common form of physical degradation of soils of the red October experienced forestry is seal root layer observed on heavily used areas and pastures. Also, we found that poorly structured soils containing little humus are prone to compaction. Methods of rooting out areas after clear cutting of forests lead to secondary soil degradation. It especially enhanced if, at the moment of stressing, the soil is in the waterlogged condition. Therefore, at reforestation we should use different reclamation processing. And this leads to the difficulty of their use in reforestation. It is established that intensive anthropogenic activity leads to degradation of soil and forest cover of the study area
