Changes in the fertility of a leached chernozem under different tillage technologies (moldboard, non-inversive, and combined tillage) were studied in a multifactor stationary field experiment established in 1985 in Voronezh oblast on a low-humus medium-deep light clayey leached chernozem. The nine-field rotation of cereals and sugar beet was practiced. It was found that the major parameters of soil fertility—the content and qualitative composition of humus and the physicochemical and physical properties of the chernozem—remained relatively stable independently from the applied primary tillage technologies. However, taking into account economic characteristics (crop yields, production costs, energy expenses, etc.), the combined tillage system proved to be most efficient. It can be recommended for cereals–sugar beet rotation systems in the central chernozemic region, as it ensures the highest efficiency of crop growing and preserves the fertility of leached chernozems.
