Abstract
The use of cover crops (CC) both as catch crops and green manures has been proposed as a suitable strategy to increase the N use efficiency of the system through decreasing the N losses, mainly in the form of NO3-, (Thorup-Kristensen et al., 2003). Although improving crop yields, both the presence of CC and their use once harvested, as green manures, may change the C/N balance of agricultural soils thus consequently affecting emissions of greenhouse gases (GHG). This study evaluates the effect of three CC (barley, Hordeum vulgare L.; vetch, Vicia villosa L.; rape, Brassica napus L.) over the GHG (N2O, CO2 and CH4) budget of an irrigated maize (Zea mays L.) system. We hypothesized that the presence and typology (e.g. legumes vs cereals) of CC in the intercrop period may affect differently the N and C dynamics of the soil, thus influencing the amount of GHG emitted comparing to a bare soil. Additionally, the incorporation of CC residues with contrasting characteristics would differently affect the net GHG budget of the entire maize cropping system.
