The long term application of nitrogen and phosphorus fertilizers led to a good evolution of slight luvic brown-reddish soil fertility characteristics after 10 years, but after 25 years, we reported a lowering of these characteristics as a result of less favourable plant nutrition with macro- and microelements. The manure applied only once every four years, in doses of 20-40 t/ha, or at the same time with the yearly doses of chemical fertilizers 50 kg N + 50 kg P2O5/ha has obviously improved the soil fertility characteristics along the 25 years of experiments.
