In NW of the Iberian Peninsula, the incidence of anthropogenic fires is very high and, due to the climatologic and topographical conditions, burnt soils are prone to high erosion risks. In recent years several environmental management techniques (BAER: burnt area emergency response) have been applied after some wildfires, but there are still few field studies about their effects on soils (the foundations of terrestrial ecosystems) and most of them are short-term. Aiming to fill this gap of knowledge, sixteen properties useful as soil quality indices (pH, WHC, total N, δN, NH-N, NO-N, and NHAc-DTPA extractable Na, K, Ca, Mg, P, Al, Fe, Mn, Cu and Zn) were studied four years after BAER application in a severely burnt area in the 0-2 and 2-5 cm depth layers of unburnt soil (US), burnt soil untreated (BS), and burnt soil treated with two BAERs techniques: rye seeding (BSS) and straw mulching (BSM).
