This scientific publication includes an information concerning the influence of distinct tillage systems on some elements and fertilization conditions of soil. Experiments were founded within experimental field of the Experimental Didactic Resort ,,Chetrosu.” Research purpose forecast the evaluation of some elements parameter modification and the soil fertilization conditions under the impact of conventional and conservative systems of the soil, the productivity of studied crops. Research objectives foresee: soil health condition, showed by the weed level, thresholds of weed injury; humidity evaluation and water storage level according the tillage systems; crops productivity level which were studied within the crop rotation. Based on the estimation of achieved results it was possible to resume the following: essential difference between weed level, thresholds of weed injury were not constant, except weed increase of perennial weed species propagated by suckers within tillage systems with superficial tillage predominance; are not constant and essential difference between tillage systems by it capacity of water storage and conservation accessible just with a slight tendency of water storage increase in the soil within tillage systems of conventional; the highest level of crops productivity were assured by the tillage system with deep ploughing predominance.
