The paper presents a possible modality of improving the fertility of an acid soil by treating it with alkaline compounds, containing essential and trace elements, resulted in the industrial process of manufacturing magnesium carbonate and oxide from dolomites. The experiment pursueds the effects of soil treatment with 2 waste types applied in different doses. The obtained results show a buffer effect on the acid soil reaction and an increase of the essential and trace elements content of the treated soil. The pH buffering process and the enrichment of essential and trace elements in soil by alkaline waste supplies establishes in soil the enhancement of global soil fertility.
