| Abstract The aim of this study was to evaluate the effects of burning and manual control of invasive species on a Latossolo Vermelho-Amarelo soil covered with Urochloa brizantha. Five soil samples were collected for pasture and forest, at 0-5 cm depth, to determine the accumulated respiration, microbial biomass carbon (MBC), mild organic matter, total organic carbon (TOC), water soluble carbon and MBC:TOC ratio. Three groups according soil grass coverage were selected: (1) group I with 33.5% of bare soil, (2) group 2 with 90% coverage and (3) group 3 with 53.4% coverage of invasive species. The highest value of TOC was found in forest (36.52 g/kg). The highest accumulative value of respiration in the soil was observed in group 3 (2.6 mg/kg) and the highest... |
