The key position of grain farming and livestock in the South of Russia in the economic sphere is due to the fact that it can be the main factor in ensuring food security and the main condition for the sustainable development of agriculture and the agro-industrial sector as a means of using soil, climatic, orographic and conditions of the land use effectively. These factors make it possible to consider an increase in grain and livestock production for the market a strategic task for the region, and first of all, as an indicator of the most efficient use of the natural resource potential of the territory. An analytical study is conducted on the database management of two multi-parameter systems, the environment and the crop and livestock production state on the basis of reports and statistical materials. The analysis of the current industries state is aimed at identifying decision-making methods for managing agricultural land productivity based on agro-ecological and landscape zoning of the territory of an agribusiness. Currently, there are conditions when it is necessary to switch to a new scientifically based model of the spatial business organization. This will allow implementing the strategy of environmentally adaptive intensification of crop and livestock production. This approach is based on the identification of seven agro-ecological groups of lands and the placement of field, forage and soil-protection crop rotations on them, taking into account the proposed model of the soil-protective complex, reducing the manifestation of water and wind erosion. Such an approach in the use of the territory of an agribusiness will correspond to the grain and livestock specialization of the third agricultural zone of the Stavropol region.

At present all the necessary information has been accumulated on current topic, and our findings confirm once again the opinions of many scientists about the positive effect of protective forest strips on the wind-resistance, snow accumulation, humidity dynamics, and infestation of crops. The article presents research data concerning the ameliorative role of protective forest strips on the crops productivity evidence from winter wheat. Remoteness from a protective forest strip substantially affected the accumulation of productive moisture by the time of winter wheat sowing. In this regard, we determined the content of productive moisture in the soil for all experimental plots. Besides, soil moisture formation strongly depended on snow accumulation. Thus, moving away from the protective forest strip resulted in decrease of the snow cover depth. At a distance of 10-20H from the protective forest strip, the snow cover depth was 25-30 cm decreasing to 5-10 cm with further increase in the distance. The overall influencing distance of protective forest strips varies from 0 to 30Í. The same trend was maintained with regard to the formation of moisture content. Impact on weediness was manifested in such a way that the smallest amount of weeds was observed at a distance of 0-10H. When moving away from the protective forest strip, the amount of weeds grew, as well as species composition, and further (30-40H) the amount of weeds per square meter decreased. The maximum wheat yield (3.86 t/ha) was obtained at a distance of 10-20H from the protective forest strip.

Natural resources potential of the territory and natural-historical mechanism of its development are pacing factors in agriculture differentiation and AIC-development. Key branches in the Stavropol Territory are crop production, sheep breeding and meat and milk cattle breeding. To meet the market demands “equating” differentiation of agricultural enterprises is implemented. Thus, in Stavropol Territory crop lands have been increased for crops required in the market that disbalanced the crop rotation, disturbed agro technologies and resulted in reduction in yields and grain quality. In the Territory 70 % of tillage is in risky agriculture. About 65 % of crop production (wheat, barley and others) are in draughty areas where out of 141 years (1861–2002) 41 % draughty, which determine high natural-climatic dependence of grain economy [1]. Annual and areal variability of grain production is also determined by topsoil heterogeneity and variety of relief. At present production of the basic market crop – winter wheat, which takes 75 % of acreage for cereals and leguminous crops, the productivity of the cultivated crop is 22.4–39.5 centner/hectare. It results in top soil changes such as compaction, fertilizer impoverishment and organic matter content (organic matter deficit is 400–700 kg/ha). Intensification of agrarian production results in quicker erosion processes, soil properties decline and lower fertility. The total area of eroded lands in the Territory is 1792000 ha [2]. That is why it is important to develop a new model of the economic use of Stavropol Territory. The main methods of study are analysis of the current status and organization of the agricultural zones of the Territory. The data were preceded with the software Statistica.
