Conteúdo: | ABSTRACT - Climate change has been linked to global warming and attributed to anthropogenic greenhouse gas (GHG) emissions. Concerns about the impact of livestock production on the environment have arisen around the world in recent years, due to the emission of methane, a GHG. The aim on this study was to evaluate performance of the H13 clone of Eucalyptus urograndis at 12 years of age, at two planting densities under integrated crop-livestock-forestry systems (ICLF). The experiment was carried out at Embrapa Beef Cattle in Campo Grande (Brazil). Trees were planted in two distributions: ICLF with eucalyptus distant 2.0 m between trees and 14.0 m between rows with a density of 357 trees ha-1 (ICLF14) and, with eucalyptus distant 2.0 m between trees and 22.0 m between rows, with a density of 227 trees ha-¹ (ICLF22). This work investigated carbon sequestration in trees, therefore a dendrological analysis was performed on trees: diameter at breast height (DBH, cm) and tree height (H, m) and the volume of wood was calculated (m³) per ha to estimate the carbon sequestered in tree trunks. The 12-year-old ICLF, with final densities close to 113 trees ha-¹, sequester carbon in the wood of logs for sawmills (4.42 Mg Eq CO2 ha-¹ year-¹ of pasture used), enough to neutralize the enteric methane emitted by beef cattle (1.8 Mg Eq CO2 emissions per 1.0 AU (animal-unit) year-¹ at the average stocking rates of pastures in Brazil (0.90 AU ha-¹), thus being able to produce carbon-neutral beef.
