The present papers has as purpose to quantify some soil chemical modifications as a result of organic and mineral system of manuring after 21 years of experimentation in crop-rotation with: sugar-beet, winter wheat and winter barley. Chemical analyses were made on the soil sampled from 0-30 cm depth, after the winter wheat, at 8 Jully 2012 and conditioned after the usual rules. The experiment has two factors: A-organic manuring: a1 - without organic manure; a2 -remanence with stable manure; a3 - fertilized with leaves and crown of sugar-beet 40 t/ha and B-fertilized with ammonium nitrate: b1 - N0; b2 - N60; b3 - N100; b4 - N150 and b5 - N200. The analyses made up: pH - H2O; hydrolytic acidity and degree of base saturation. In conclusion, applying of mineral fertilizer, negatively influenced the soil pH, but applying stable manure, in posterior effect, this was improved. Ammonium nitrogen increased hydrolytic acidity, being required soil amendment with lime. Degree of base saturation achieved significant more values in the variants with organic fertilization.
