Essay

The dissertation deals with the problems connected to the determination of agronomical and agroecological evaluation of the traditional and new fertilizing systems in the 8-years field crop rotation in the long-termed experiment on the dernovo-podzol loamy sand soil on the Left-Bank part of Polyssia zone. The subjects under study were the effectiveness of growing of winter wheat, winter rye, spring barley and oats without fertilizers and at the organic, mineral, organic-mineral, alternative and complexive organic-mineral fertilizing systems with the elements of biologization and the crop yields analisys depending on the weather conditions during the growing periods - favourable, overhumid and of the mixed type (with the features of aridity and overhumidity). The fact is proved that during 1991-2002 years in the zone of Polyssia the average air temperature during the growing period increased on 0,7оC and quantity of sediments became on 6% lower, the 80% of the years were unfavourable as for weather conditions. It was stated that the stabilizing factor in any weather conditions is scientifically based fertilizing system, which foresees complexive application of farm -yard manure and mineral fertilizers with additional dressing of the by-products of plantgrowing - straw, and green manere as well the organic-mineral fertilizers which provides at the favourable weather conditions obtaining the yields of grain of winter cereals up to 60-70 centners per hectar.
