A laboratory incubation study with clover grass pasture soils of seven different ages (0, 1, 2, 3, 4, 5, and 16 production years) was carried out to determine initial soil carbon (C) and nitrogen (N) stocks and potentials for greenhouse gas emissions (N2O and CO2). Compared with the soil from the recently established pasture, an increase of total soil C and N was observed along with pasture age. Greenhouse gas emissions were low and not significantly different among the soils from younger pastures (0–5 years), but especially N2O emissions increased markedly in the soil from 16-year-old grass–clover. Low emissions might mainly be due to an early C limitation occurring in the soils from younger pastures, which was also corroborated by decreasing levels of... |

A laboratory incubation study with clover grass pasture soils of six different ages (0, 1, 2, 3, 4, 5, and 16 production years) was carried out to determine initial soil carbon (C) and nitrogen (N) stocks and their effects on initial greenhouse gas (GHG) emissions (N2O and CO2) after soil incorporation of the grass-clover pastures. Compared to the soil from the recently established pasture, a significant increase of total soil C and N was observed after 2 years, which was generally increasing with pasture age. GHG emissions were not significantly different among the soils from younger pastures (0 to 5 years), but especially N2O emissions increased markedly in the soil from 16-year old grass-clover. This might mainly be due to an early carbon limitation... |
