Conteúdo: | Abstract: Pastures are of central importance in food production and provide several ecosystem services. This study aimed to identify whether intensification of pasture-based animal production systems have a higher capacity to store carbon in the soil than other cattle exploitation models (natural grassland without anthropogenic interactions, natural grassland fertilized and overseeded with exotic species and annual pastures with frequent soil disturbance). The parameters evaluated were: carbon stock (CS), total organic carbon (TOC), particle size, porosity, density at different soil strata, root system and forage production. Forage DM production varied significantly with means ranging from 6,615 to 13,000 kg ha?1 year?1 for natural grassland (NG) and permanent pasture (PP), respectively. Improved natural grassland (ING) and NG presented higher density and root diameter than PP and annual pasture (AP). Forage systems significantly influenced soil porosity and density, with NP and INP showing lower soil densities and higher soil porosities. CS (0?100 cm) were similar between NP (270 Mg ha?1), INP (255 Mg ha?1), PP (274 Mg ha?1), and AP systems (256 Mg ha?1). Intensification of pasture-based animal production systems does not change soil CS in five years in a sub-tropical highlands climate in southern Brazil.
