Potential role of compost and green manure amendment to mitigate soil GHGs emissions in Mediterranean drip irrigated maize production systems
Organic fertilization can preserve soil organic matter (SOM) and is foreseen as an effective strategy to reduce green house gases (GHGs) emissions in agriculture. However, its effectiveness needs to be clarified under specific climate, crop management and soil characteristics. A field experiment was carried out in a Mediterranean drip irrigated maize system to assess the pattern of soil CO.sub.2 and N.sub.2O fluxes in response to the replacement of a typical bare fallow-maize cycle under urea fertilization (130 kg N ha.sup.-1 y.sup.-1) (CONV) with: (i) bare fallow-maize cycles under two doses of compost (COM1 and COM2, 130 and 260 kg N ha.sup.-1 y.sup.-1, respectively) and (ii) a vetch-maize cycle, with vetch incorporation as green manure (130 kg N ha.sup.-1 y.sup.-1) (GMAN).
