ACIDIFICATION PROCESSES IN SOILS OF BISTRA HIDROGRAPHYC BASIN PUBLISHEDNicoleta Nemeş
In this paper we studied the processes that generate acidity in the soils and the factors that determinate it. For this we analysed a lot of pedological profile, a sample from Obreja and Glimboca, in Bistra Hydrographyc Basin, Caraş- Severin County. From the pedological profile analyses we established that the acid soils, like luvosoils and districambosoils are predominant in the researches area and their acidity are determinate by the bases cations debasification and it forms a impermeable water horizon, Bt, that leads in time to oxide-reduction processes that will generate a soil acidification.
