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