Abstract

The Brazilian vegetal cover has suffered appreciable modifications, for some time now, due to successive human interventions. Important ecosystems such as the Atlantic Rainforest, the Amazon forest and the Cerrado, have been losing a good deal of their original covers, with deforestation, making room predominantly for cattle farming activities. It is predictable that the effects of different covers, their removal and cultivation transmit to the soil different effects and problems. In this sense the objective is to evaluate the impacts deriving from the removal of the original covers and their subsequent agricultural use, selecting, for this purpose, different Brazilian bioclimatic regions, such as mentioned above and taking as the primary attributes of analysis the evolution of organic material linked to the modifications to the structure/aggregation of the soils.
