Biologization and resource saving - the most important directions of innovative development of agriculture in the steppe conditions

Increased sustainability of agriculture in Russia, with growing demand for food, the desire to reduce imports and save internal resources for modernization and intensification of agricultural production in many respects determines the need for development in every sector biologizing farming systems. Promising the opportunity to develop the principles of ecologically and economically sound crop rotation with an adjustable intake of organic matter in the soil. The organic matter of a certain quality, as the basis for the reproduction of soil fertility, and resource-saving technologies of cultivation of agricultural crops, taking into account the requirements of crops and agro-ecological conditions. Such approaches are possible in order to avoid soil toxicosis, the most promising and cost-effective in relation to when investing or limitations. 25 years of research show stable opportunities for cost-effective production, but also suggest the need for studies of content producers and their toxins in plant residues. Excluding these factors increase the risk of investment in long-term crop production. Mixed crops, particularly perennial crops almost 2 times more effective than planting sudan grass. Individual culture up to ten times less effective in comparison with cereals, legumes. The presence of nearly identical pathogen in these cultures and leads to a drop in their attractiveness as an accumulation of biorganic mass and not always cost-effective to use in a live target.
