Abstract

GAITAN, Juan José; BRAN, Donaldo Eduardo  and  MURRAY, Francisco. Effect of burn severity on the soil organic carbon concentration mounds and intermounds in the monte austral. Cienc. suelo [online]. 2007, vol.25, n.2, pp.195-199. ISSN 1850-2067.

The effect of burn severity on soil organic carbon concentration (COS) in vegetated mounds and in bare soil intermounds was evaluated 4 years after the occurrence of a natural fire in an area of the Monte Austral (Río Negro province). The mounds act as "fertility islands" since COS concentration was higher than in the intermounds. The COS concentration in the intermounds was not affected by fire. On the other hand, in the mounds a decrease in the COS concentration was found when the burn severity increased. The COS loss could induce rangelands degradation, therefore fire management practices should tend to the realization of low severity burns.

Keywords : Burn; Organic matter; Mounds; Intermounds.
