The basis of rational distribution of fruit crops is the principle of consistency between their requirements to soil conditions and soil features on specific indicators: the level of salt content, moisture content, mechanical composition, density, and others. In this regard, the study and evaluation of soil and nvironmental conditions using the perspective methods of accounting and systematization of information on specific fruit farms and orchards quarters are very actual. For the territory of Krasnodar Region the content and depth of the carbonate - one of the limiting factors of growth of fruit crops (except apricot) were analyzed. The forecast of optimal placement of fruit crops depending on soil conditions was carried out with the help of geographic information technologies (GIS) based on computer databases spatially coordinated data, coupled with special software and hardware for data entry, storage and multipurpose analysis. On the basis of GIS the computer maps were built, reflecting the soil properties for each indicator were created. As a result of the work it is carried out the systematization of soil and resource data for the Krasnodar Region on the indicators of gardens suitability based on data bases (DB), coupled with the special software and hardware. The results of our work are presented on the example of identifying areas with a high content of CaCO3 in the soil layers at depths of up to 1 m across the region. The computer maps for ecologically accurate and economically viable placement of fruit types on the macrozones in the landscape are created.

The results of the study of microbial communities of the arable layer of two types of zonal soils under the peach tree in the Southern Region are presented. The substantiation of relevance of carrying out system monitoring of microbiological diversity under the conditions of garden monoculture is made. The main purpose of the work is a comparative assessment of changes in microbiological indicators of brown forest slightly unsaturated soil and leached chernozem in anthropogenically transformed ecosystems. The experimental plots were located in the plantations of fruitbearing peach of high-yielding varieties zoned in the region in the humid subtropical climate of the Black sea coast and the Central zone of the Krasnodar territory. The microflora features of upper (arable) soil layer were analyzed. Based on the climatic feature of region the soil for research was selected in the winter period � in the first decade of December. For microbiological studies, the main groups of soil microorganisms � reducers of plant residues that form a microbial complex were selected . The main morphological groups (bacteria, actinobacteria, and micromycetes) of soil microorganisms were accounted for using traditional methods. The analysis of the number of microorganisms was carried out in relation to agrochemical indicators of soils and weather conditions during the sampling period. The structure of the microbocenosis was quantitatively dominated by the physiological group of saprophytic bacteria. On average, the number of actinobacteria and micromycetes was 1-2 orders of magnitude lower. The arable layer of leached black soil under the peach orchard was characterized by higher values of saprotrophic aerobic bacteria in comparison with brown soil. The content of producers of antibiotic substances � actinobacteria in leached chernozem was 2.4 times lower. The population of the upper layer of two types of soil containing the bulk of plant residues differed slightly. Some excess of the content of soil fungi in the borozem is probably due to higher soil acidity. The revealed features of the composition of the microbocenosis of two types of soils are the basis for continuing the biomonitoring, which allows using agricultural methods to develop the possible ways of rational use of microorganisms activity to increase in soil fertility.

Under of diversity of soil-climatic conditions the abiotic factors act as limiting and they destabilize the system of growth and development of plants in a fruit agricenoses. The role of adaptation reactions of varieties of fruit crops increases under these conditions. The main purpose of research was the study of dynamics of metabolites of apple-tree varieties of Idared, Prikubanskoye, Ligol varieties on CK4 rootstock under the conditions of different moisture of spring and summer period, including the double use of special fertilizers in combination with growth regulators. In article the analysis of change of weather conditions in May-August is given; dynamics of fractional composition of water is studied. Data on dynamics of carbohydrates and the content of organic acids and phenolic compounds are presented. Products of sugars oxidation are researched, realization of reproductive function of apple-tree plants is analysed. At this stage of research it was defined that Idared and Prikubanskoye apple-trees differed in the highest and stable content of free water in the leaves during the period from June to August and the raised content of phenolic compounds that promotes stabilization of regulatory functions of plants. Rather high level of synthetic reactions is revealed at apple-trees of Idared, Prikubanskoye and Ligol when determining the dynamics of protein content, carbohydrates, ascorbic acid and organic acids. The responsiveness of apple-tree plants on leaves processings by water solutions of special fertilizers and regulators of growth is shown. On the basis of the data obtained in research the conclusion is made that the studied apple-tree varieties are suitable for creation of steady fruit agric cenosis under the conditions of the South of Russia.
