Objects of research - basic properties Regularities of changes in the typical black soil under different methods of fertilizing the soil, economic and environmental parameters using different forms of fertilizers in crop rotations korotkorotatsiynyh. Goals and Objectives of work - to examine the impact of organic and mineral fertilizers in their application in crop rotations on yield korotkorotatsiynyh Agriculture crops and crop productivity in general. Determining whether to reduce the doses of fertilizers using byproducts (straw) grains and legumes and fertilizer on sugar beet tops; determine the impact of by-products in combination and compared with mineral fertilizers on soil fertility. According to the data for variations where applied fertilizer was observed lengthening the growing season for 3-7 days, compared with control. Improvement of plant nutrient contributed to lengthening growing season and more comprehensive use of abiotic and biotic factors that form the harvest. In both crop rotations of fertilizer application significantly increased the overall costs of crop production and reduced profitability. The highest economic efficiency was observed for variants with an organic fertilizer system. The use of green manure and green by-products (tops), where there is no need for making compensation nitrogen increases the economic efficiency of crop cultivation.
