Abstract

The effects of 2 fire intensities on soil microbial biomass and soil respiration were measured in a field-scale experiment on a sweet chestnut forest slope in St. Antonino, southern Switzerland. 20 hours after a higher intensity fire on a slope with double fuel load, soil respiration had increased and remained high for several months. The AA. suggest that this would increase the risk of nutrient outwash from the burnt slope. However, the size of the microbial biomass was unchanged compared to unburnt control sites. Soil microbial biomass therefore played no significant role in limiting nutrient losses after the fire
