THE PLACE OF SCIENTIFICALLY GROUNDED CROP ROTATIONS IN MODERN AGRICULTURE

Abstract

The use o f scientifically grounded crop rotations in modern geoponics are analyzed in the article and the reasons which led to abuse o f the process o f reforming the village, the distribution o f land and the appearance o f its new owners are presented. Such reasons are: the transition from planned maintenance o f crop industry to unplanned, when the structure of sowing areas can vary almost every year. Under these conditions, to conduct any crop rotation perm anently is impossible; division o f crops on market and non-market, profitable and unprofitable during market instability; lack o f domestic market due to lack o f stockbreeding, which ensures the presence o f internal market o f crop production; noncompliance o f recommended term o f crops return to their previous cultivation place, when sunflower, for example, in whole field is grown not only in the 10-field crop rotation and in three-five-field crop rotation; no need for growing forage crops, m ost o f which positively affects the fertility o f the soil and are good preceding crops for grain and industrial crops; lack o f long-term (20 years or more) lease o f land, and due to the frequent change o f land areas, it is impossible to comply with developed crop rotation regardless o f whether it will be scientifically proven or not. The Resolution o f the Cabinet o f Ministers o f Ukraine № 164 dated 11 February 2010 is separately mentioned, which implies the need in project development o f land management and the scheme o f scientifically grounded crop rotations in each farm, the area o f land in which 100 ha or more. The relation o f scientists-agrarians and producers to this Resolution and to the need in keeping scientifically based crop rotations is presented.
