The modern clearcutting of Tropical Forest ecosystems leads to soil erosion and destruction of silicon enriched horizons. The deeper and more ancient soil layers with Fe and A1 high contents, so called laterite and hardpan, become common for many hilly tropical and subtropical agricultural areas. 

Brazilian Atlantic geographical region is placed on the Brazilian hilly plain and its eastern slope. The southern part of this region is characterized by subtropical climate, the active temperature coefficient is a little bit less than 1.0 and biogeochemical cycling coefficient is a little bit higher than in typical Tropical Wet Forest ecosystems (Cb is 0.15). In the northern part the very low fertile Chromic Luvisols are predominant in Tropical Forest ecosystems and in the southern part the coniferous forests grow on Nitosols.
