Abstract


The present article has monitored the main properties of forest soils from Brașov County, covering a period from 1980 until present times. All the analyses were centralized in analysis bulletins and are part of a national data base realized by INCDS „Marin Drăcea” based on forest management plans. Per total, 404 soil profiles and 1083 pedo-genetic horizons were analyzed. The most widespread forest soils in Brașov County are the ones from Cambisol class, holding 70% of total soils, the highest share being obtained by eutric cambisoils. The average pH values are situated in the interval 4-5 in both horizons for dystric cambisol and within 5-6 interval for eutric cambisol. The soils with the highest content of humus, from the ten identified ones, are soils from the Spodisol class -crypto podzol and entic podzol. On the other hand, the haplic podzol, a soil from the same class, registers the smallest value of total cationic exchange capacity. The highest value of this index was obtained for rendzic leptosol, a soil with an alkaline reaction which is not very acid like in the case of haplic podzol.
