The role of factor “crop rotation” at soil fertility and prodactivity management

In the article issues about role factor “crop rotation” at ecological agriculture had described. They concern of the place crop rotation in united system of soil fertility and productivity management, relationships with others factors and local conditions, as well as the production and economical efficiency of different kinds crop rotation at the conditions of grey forest soils at Vladimir opolye. As a result of made investigation, by theoretical key, complex logical scheme of management of triun category “soil fertility + productivity + ecology” had constructed. The signification role of crop rotation at ecological agriculture and the strengthening with it’s help of influence of others production factor on crop capacity (synergic phenomenon) had identified. The implement of economical estimation of different kind crop rotations had assisted to formulate next major summary positions: 1) about more high production and economical efficiency of grain grass-fallow crop rotation (with busy fallow) and grain grass-tilled crop rotation (with potato) in comparison with specialize grain crop rotation, as well as with grain grass-fallow crop rotation, including pure fallow; 2) about the insignificant reducing of technological expenses on unit product in grain grass-fallows crop rotation (around 4 %) at replacement traditional moldboard plowing to antierosion soil processing.
