It has been studied the influence of traditional and minimum tillage on bulk density, soil pedality, humus content, the amount of exchange bases and yield of barley grain after phytomelioration of chernozem southern. Research was carried out for six years in the grain (lentils, spring wheat, oats, barley) and grass crop rotation links (alfalfa third year of use, spring wheat, oats, barley). It was found out that minimizing the basic tillage in the grass link contributed to the preservation of soil fertility gained by phyto ameliorant. The lowest values of soil pedality were after the formation digestion of perennial grass remains (1.12 g / cm3) after traditional tillage and disking (1.18 g / cm3). In the fourth and subsequent years, the value of soil density in the grass link was baseline. In the variant with minimum tillage after six years of spring crops cultivation in the grass link soil structuring was 77.6%. It exceeded the number of healthy aggregates in grain link by 5.3%. During the years of tillage in the grass link the humus content decreased from 3.4 to 3.15% after plowing and up to 3.26% after disking, which exceeded the grain link by 0.05 and 0.10%, respectively. Barley in the grass link is more responsive to the minimum tillage compared with grain link. Increased productivity in this variant was recorded for five years (27.5%), when using traditional tillage – for four years (18.0%).
