Descripción:	Determine the soil quality and the emissions of mineralizable soil carbon (C-CO2) in conventional and integrated systems in the Midwest region of Brazil. Methods: The evaluated systems include original pasture (OP), reformed pasture (RP), conventional tillage (CT), direct seeding (DS), and cultivated eucalyptus forest (CF), as well as crop-livestock integration (CLI) and crop-livestock-forest integration (CLFI) systems in both the pasture phase (p) and crop phase (c). The soil organic carbon (SOC), carbon and carbon stock (StoC) of the particulate organic matter (C-POM) and mineral-associated organic matter (C-OMM) fractions, indexes of soil quality, and daily CO2 emission and accumulation in the 0–0.05, 0.05–0.10, 0.10–0.20, and 0.20–0.40 m layers were determined. Results: The CLIp and CLIc systems had the highest SOC contents, reaching 15.47 and 15.04 g kg−1 of C in the 0–0.05 m layer, respectively. For C-POM, the integrated systems in the pasture phase had the highest contents and stocks, storing up to 19 t ha−1 at 0.4 m. For C-OMM, CLIc had the highest contents and stocks, storing up to 57 t ha−1 of C up to 0.4 m. The systems with pasture had the best carbon management indexes. The LI, L, C-POM stock, and CMI remained the most representative variables related to the CLFIp system. Conclusions: integrated systems improve soil quality and store Carbon, especially in recalcitrant fractions of the SOM, with reduced C-CO2 emis- sions, helping to mitigate climate change in the Central-West region of Brazil.
