Soil carbon and nitrogen under different land-use and landscape loca-tions in central Brazil

In Central Brazil, plateaus, the most common geomorphologic form, have been undergoing intense conversion from native vegetation to pasture and agriculture in recent decades. We used carbon stable isotope ratios (δ13C) nitrogen (δ15N) assess possible changes soil organic matter dynamics under such land use modifications. This study aimed evaluate differences δ13C δ15N C N stocks between agricultural or areas different locations of a plateau savannas Brazil. sampled up 100 cm depth summit no-tillage conventional tillage on border plateau, as well soils both landscape locations.
