Lukyanets V. Optimization of the structure of the agricultural lands and predecessors of winter wheat for the Cherkassy region at the transition of village to market relations

The structure of agricultural lands and precursors of winter wheat. The purpose of investigations - to develop the optimal structure of agricultural lands for the Cherkssy region. The research methods are analytical, field, laboratory and statistical. The land grouping according to water erosion display is conducted, the ways of using arable lands and areas removed from use are determined and the model of diversification for ensuring stead-fastly high productivity of winter wheat is elaborated. The recommendations concerning putting of arable lands on slopes with steepness 5 grades and more on the natural forage lands are worked out what reduces the price of fodder production and protects sloping lands from further erosion. The removal of bare fallow, maize for silage and stubble cereals from the structure of winter wheat precursors at the expense of the increase of perennial grasses in the precursor structure will promote the intensification of the wheat kernel production and the two-year use of perennial grasses instead of one-year one secures better restoring soil fertility without surchar ges of money and material resources for that. The research results are introduced in Uman' district of Cherkasy region over a totsl area over 100 ha. The sphere of application - the agricultural production.
