The quality of the soil cover due to the use of various agricultural technologies is the subject of this study. The large number of agricultural technological works that are executed under the conventional technologies can reduce the natural soil fertility by modifying the soil agrochemical indicators. These negative phenomena have led to the emergence and development of the concept called "system of agricultural works for soil conservation" [8], according to which the system of works needs to maintain or improve the productive potential of the soil. The paper presents the results of the researches carried out in order to know the effect caused by the long application of the various soil cultivation systems, on the chernozem type of Baragan Plain, soil with very high fertility potential, where the humus content is on average 3.8%. Having as comparison base the classical soil cultivation technology performed by classic plowing (conventional soil tillage), at a depth of 22 cm, various variants with low soil works were taken into consideration, namely the replacement of classical works with disc or chisel works (conservative soil tillage).
