Abstract

The middle region of Minas Gerais / High Paranaíba originally covered by Cerrado vegetation has been heavily deforested area for being a pioneer expansion of agribusiness. Among the various environmental changes related to deforestation include soil erosion and imbalances in stocks and the nature of carbon sources. Results of analysis of total carbon (Ctotal) and carbon isotope (δ 13C) of four categories of use - remnant of cerrado tree, rotation of soybeans and corn in no-tillage, pasture and degraded pasture managed - revealed that the conversion of use and management led to important changes in the nature and content of the soil carbon. The results presented can serve as important indicators of environmental impacts when natural ecosystems are converted into agricultural systems without the adoption of appropriate management.
