Conteúdo: | ABSTRACT - The prediction of soil organic carbon (SOC) stocks, enteric emissions and beef production is required for planning of low-carbon management practices in livestock systems. The use of mechanistic modeling is well-suited for this purpose, but it still represents a knowledge gap in Brazil. The objective of this study was to investigate the use of the Manure-DNDC model to simulate SOC and to estimate the CO2eq emission intensity of beef produced at two sites in the Cerrado biome, which adopted crop-livestock integrated system. There was a good agreement between measured and estimated C stock data from both sites, suggesting a good performance of Manure-DNDC model. At the EMBRAPA site, the emission intensity for integrated crop-livestock (ICL) was 10 kgCO2eq.kgBeef-¹ , 10% higher than of integrated crop-livestock-forestry (ICLF22 and ICLF14) systems. At the TRIJUNCAO site, emission intensity was 9 kgCO2eq.kgBeef-¹ for Low Carbon Brazilian Beef (LCBB) system, which was similar with Management Farm (MF). The predictions of the Manure-DNDC model satisfactorily predicted GHG emissions and capture for the Cerrado condition, whose results pointed out to the potential of integrated systems to mitigate GHG emissions.
