Written by Gheorghe JIGAU

Modern agriculture is distinguished from that practiced in seventies-eighties of last century through diversification of tillage methods, fertilization and soil maintenance. Alternative tillage systems lead to the formation of pedogenetic ambiance intrinsic that differs essentially from the ambiance created in the traditional system. No-Till tillage system favors the process of humus formation with his accumulation in the 0-20 cm layer. Also it is taking place preponderant accumulation of N-NO3, N-NH4, mobile forms of phosphorus and exchangeable potassium. Mini-Till and deep loosening without returning furrow lead to creating an ambiance in which the processes of humus formation only ensures sufficient compensation for losses of humus during crop growing.
