Description:	Slash-and-burn land-use is associated with significant C-emissions during the burn. Substitution of fire by slash-and-mulch has been proposed as an alternative management option which could potentially reduce emissions and improve soil quality by increasing C-stocks in SOM. This implies that part of aboveground biomass, transferred to the soil surface as mulch, actually is incorporated into the topsoil OM-pool. Here we investigate if slash-and-mulch of fallow regrowth immobilises significant amounts of biomass and increases topsoil OM-contents for prolonged time-spans.
