Gepenko A. Technological Burden Control to Typical Chernozem in the Left-bank Part of the Forest-Steppe Region of Ukraine

The results of the technological burden control investigations to the agrogenic typical chernozem are stated in the dissertation. Energetic evaluation of agrotechnical methods in various short rotation of crops and in different ways of the main soil tillage in crop rotation is made. Some soil transformation mechanisms at the structural and agregate level at different technological burden are determined and proved. Maximally permissible contents of the non-aggregate ESP according to which the level of technological burden to the soil is ecologically safe and it does not exceed the permissible limits from the side of the soil system stability is calculated. Recommendations as to the optimal correlation of agricultural crops in a short rotation and the choice of the main agrogenic soil tillage on the base of technological burden are worked out.
