Description
The article presents the results of a study of microbiological content of the soil after microbial protection of plants. Preparations were obtained by the technology developed by Ltd. "Kuban agrotehnoloogy". We have established the presence of bacteria Azotobacter chroococcum and fungus Trichoderma viride in the soil. Investigation of Trichoderma viride was made with using plant residues. It is proved that the use of microbiological preparations for plant protection have positive effect to improve the microbiological composition of soil. We have substantiated the example of the summary application of Azotobacter chroococcum and Trichoderma viride for plant protection. A number of provisions of the article have a scientific basis of view for the "food chain" microorgaisms. Trichoderma viride enzymatic hydrolysis products are good food source for Azotobacter chroococcum . Azotobacter chroococcum facilitates transfer of available nitrogen for plant nutrition. These microbiological preparatioты were recommended for seed treatment of plants during the growing season and crop residues after harvest. We used such culture media as Capek, Beijerinck and Ashby. Soil samples for research were selected by "Temizhbekskaya" Ltd in the Stavropol region. The study may be interested for agronomists, biotechnologists, mycologists, microbiologists

COMPLEX COMPOST AND DETOXICATION OF AGROLANDSCAPE SYSTEMS
DescriptionToxicity complex compost arises during compiling of organomineral mixtures of various waste of life, agriculture and mineral industries. One of detoxification factors of complex compost is the ability of heavy metal cations to the formation insoluble compounds, which are fixed by clay materials and different disperse systems, and differ markedly by calcium content, acidity and humus soil-absorbing complex

COMPLEX COMPOST AND CIRCULATION OF NITROGEN AND CARBON AT THE AGROLANDSCAPE SYSTEMS
DescriptionComplex compost includes all elements of the periodic table and is valuable due to the complexity of its system. Among the elements forming a chemical composition of the complex compost we can identify two most important, which are distinguishing a specific character of the interaction with each other and defining the basic processes to ensure vegetation of living system - nitrogen and carbon. Nitrogen determines the rate of energy and connects with living forms of organic matter; it is included as the part of protein and is a major element in determining the productivity of ecosystems. At the cycle of carbon its organic forms and carbon dioxide take a part, presenting the main factors of the processes of respiration and photosynthesis

COMPLEX COMPOST AND ECOLOGICAL NICHE OF LIVING ORGANISMS IN AGROLANDSCAPES
DescriptionEcological niche acts as an important evolutionary function of living organisms in the ecosystem and determines its properties, which are caused by the nutrient requirements, mobility, ability to reproduction, biochemical features, structural features limits tolerance to environmental conditions, opportunities performing certain actions in the specific biocenosis; in the process of divergence (species, their internal and external properties and abiotic characteristics) features of ecological niches are changed , there are new kinds of living organisms and, of course, the formation of new ecological niches

MULTI-LAYER COMPOST AS AN IMPORTANT SOURCE OF ENRICHMENT OF SOIL NUTRI-ENTS
DescriptionMulticomponent compost represents a good environment for a significant number of species of living organisms and populations which produce enzymes, vitamins and other active substances. Chemical and physical properties of complicated composts are heterogeneous and polydisperse interim systems, and on the gene pool of living organisms are a rich comprehensive substratum. The heterogeneity of complicated composts of characterized by a very wide range of organisms which using animal waste and isolating of germinating seeds and spores of higher and lower plants

COMBINED PLANTING OF ANNUAL CROPS - IMPORTANT PROBLEM OF PRACTICAL ECOLOGY
DescriptionSelf-regulation of agricultural systems is based upon taking into account the interaction of their components released in variety of species and trophic relations; agricultural systems is diversified in towards a sustainable, productive and strategic development of the systems; one of the most promising areas of diversification of agricultural systems is considered to be an introduction to the practice of combining crops, known in agriculture for a long time, which shows us the nature. The most developed technology for creating combined crops is the practice of creating mixtures and the nature of the relationship between their different components

CURRENT STATUS AND PROSPECTS OF MANAGEMENT IN AGRARIAN SECTOR THE STAVROPOL REGION
DescriptionCurrently, when solving the problem of greening it is addressed to the technical and technological capabilities. These means can achieve some improvement of the environment in a particular region, but they are not enough to solve the problem of pollution in the whole country and the world. The problem in general can be solved only through an integrated analysis of the set of economic and ecological processes, which makes it possible not only to improve the development, but also to manage the process of impacts on the environment itself

MODERN CONDITION OF STUDYING OF LICHENS FLORA OF NAKHCHIVAN AUTONOMOUS REPUBLIC OF AZERBAIJAN
DescriptionThe article is devoted to results of researching of lichens flora of Nakhchivan AR Azerbaijan. During 2003 - 2009 specific structure, regular structure, laws of distribution on high-rise zones, ecobiomorphe, geographical features of lichenflora, rare species of lichens and the problem of their preservation were studied. In the region, there are 347 species of flora, 6 variations and 5 forms of the lichens concerning 83 genus and 38 families are revealed. From them, 17 families, 35 genus and 138 species are noted for the first time for research territory. In the article the facts about ecomorphological features of 12 new kinds of lichens of Nahchivan АR are given
