Were evaluated a crop-livestock integration system - CLIS (corn+brachiaria/bean/cotton/soybean) and no-tillage system - NTS (sunflower/millet/soybea /corn). The vegetal coverage of natural Cerrado, adjacent to NTS and CLIS, was considered as the original soil condition. Soil samples were collected at depths of 0.0-5.0 and 5.0-10.0 cm in full random experimental design. The CLIS showed the greatest mass and levels of C-LOM (5-10 cm), and too greatest mass and levels of C and N of FLF (0-10 cm) when compared with the NTS. Regarding the Cerrado, the CLIS showed higher values for N-LOM and 1δ15N-LOM (0-5 cm), C and N of FLF (0-5 cm). Through physical indicators LOM and FLF, it was possible to infer that the CLIS increased the SOM fractions when compared to the NTS. 2012 artículo científico 1679-9275 https://www.redalyc.org/articulo.oa?id=303025342011 en http://www.redalyc.org/revista.oa?id=3030 Acta Scientiarum.
