Subject of investigation - a short rotation crop rotation scheme with an improved structure. Research Methodology - modeling of objects and processes in the stationary field experiments, laboratory and field, statistical, data grouping, calculation and constructive method of ecological, economic and energy analysis. It is established that a high yield of winter wheat crop rotation was obtained on all of the predecessor fallow. The predecessors of green manure pairs and winter rape is almost equal and provided yields of winter wheat at a level (82-80%). The high level of productivity was obtained in sunflower crop rotation, where his share of the crop rotation did not exceed 20%. Due to the introduction of moderate doses of mineral fertilizers (N60P60) is not achieved a significant weakening in the culture of the negative impact of at least satisfactory parts of his predecessors and crop rotation. Ensuring the sufficient and a positive balance of humus in the studied crop rotation is achieved through the introduction of moderate doses of mineral fertilizers (N60R60), an increase in the proportion of green manure and the use of a pair of by-products of cultures as a reserve of organic matter. Mineral fertilizers had a positive impact on all physical indicators, the output energy from crops, the balance of humus, but reduced the key indicators of economic efficiency of crop rotations of the reasons for the high fertilizer prices and low overall productivity of crop rotation. On a set of all evaluation criteria (natural, energy, environmental and economic), the most promising groups of crop rotation patterns were variants of a specific gravity of pure steam 20%, grain - 40% (including food groups from 20 to 40%) and industrial crops - 40% (including 20% ??sunflower and 20% of winter rape). It is recommended to increase the share of sunflower to the evidence-based standards (no more than 20% of the field crop rotation) by replacing part of the acreage of sunflower oilseed rape (up to 20% of the field crop rotation), which will increase the group of the most profitable commercial crops in crop rotations short rotation of up to 40%.
