Fertilitatea și productivitatea cernoziomului tipic pe diferite sisteme de fertilizare în asolament

Stadnic, Stanislav | Boincean, Boris
The fertility of the soil and productivity of crops, used in agriculture, are determined by the influence of biological, agrophysical and agrochemical factors, together with the rational combination of fertilization and tillage systems within the crop rotation. The research results of the use of different fertilization systems in crop rotation on the Typical Chernozem from the Bălţi steppe during the long-term experiment demonstrate the decrease in the content of organic matter in the soil profile, the stabilization of productivity of crops after the initial increase and a tendency of decreasing productivity in the last two decades. The given situa-tion is determined, to a large extent, by the fact that the share of soil fertility in the formation of crop yields and crop rotation productivity is very high and varies within the limits of 70-76%.
