英文摘要	Green manure (GM) is supported by agronomical protocols for improving soil fertility and sustainability of agriculture. The environmental and agronomical efficiency of GM can be evaluated in terms of carbon dioxide (CO2) and water (H2O) fluxes. These fluxes were monitored by eddy covariance method, together with meteorological data, before and after faba bean (Vicia faba spp. minor L.) GM performed in a semi-arid Mediterranean region. The addition of fresh biomass into the soil increases the microbial activity with a positive priming effect: the addition of ready decomposable carbon to the soil increased CO2 respiration and surface evaporation. The measured C emitted under CO2 form during the whole experimental period corresponded to 78% of the C incorporated, while evaporated H2O in the same period represented 72% of water supplied by encapsulated biomass and precipitations. The cumulated loss of C after GM until the soil preparation of the successive crop was 2957 kgC ha(-1), in the same period 200 mmH(2)O were lost by soil evaporation.
