THE IMPROVING OF EFFICIENCY OF TECHNOLOGIES AT THE EXPENSE OF CHOICE OF RATIONAL MODEL OF TRACTOR BY CRITERIA OF ECOLOGICAL AND POWER EFFICIENCY

New approaches as evaluated by the mechanical affecting on the soil and the criteria of ecological estimation, directly characterizing the affecting of wheeled and caterpillar movers on the soil are presented in the article. As a result for perfection of structurally-regime parameters of the hauling field energy the concept of virtual mobile energymeans (МEM) and criteria of his efficiency are set forth. For the ground of perspective ways, methods and receptions of increase of ecological efficiency of MEM determination of meaningfulness of influence of each offers of structurally-regime parameters on the index of the affecting on the soil "U" with the use of derivative of first-order. Coefficients allowing to estimate ecological and power efficiency of the МТА in technology on exceeding of level of the mechanical affecting on the soil are presented. The algorithm of choice of model row of tractors is worked out in a certain hauling class on the level of making more compact influence of the МТА. On the basis of correlation of losses from violation of agrotechnical terms and losses of harvest from the anthropogenic loading on an agrocenosis the rational model of tractor is chosen.
