The research on the application of different soil tillage systems enjoys considerable worldwide popularity, and this can be explained by the effect of soil tillage on the conservation of water resources of the soil, as well as on the production costs. Yet, the main objective of this kind of research is the identification of an appropriate balance between the effects of soil tillage systems on soil quality and on yield. After 12 years of experimentation at ARDS Turda, changes in soil pH, from low acid and neutral to low alkaline in all experimental variants. In the case of the classical system (CS) there is a slight reduction of the humus content in the surface layer of the soil on the first cm at both levels of fertilization but instead there are increases on the deeper layers in the variant with additional fertilization. In the MT system there is a slight increase of total N in the first cm in both fertilization variants. Increases content in phosphorus in the MT system, from a weak content to low content. There is an increase in the K content, especially in the arable layer in the MT system compared to CS. The average yields recorded at crops had lower values especially in the conservative system on the first years.
