The results showed that the mean values of soil pH, EC and basic cations were significantly higher three months after the wildfire in the burned area than in samples collected at adjacent, unburned sampling sites, and gradually decreased thereafter.
The nitric-N increased consistently and linearly in time after the wildfire in all the samples, more intensely inside the burned area.
Mean ammonium-N levels were nearly constant in burned and unburned samples almost across the entire
study period, and increased in the burned area fifteen months after the fire. Sulfate-S and P showed no significant
variations based on sample status (i.e., burned or unburned) or sampling time, possibly because of their
particular dynamics in volcanic soils. These results point to a limited loss of nutrients, therefore suggesting that
the possibility of intense post-fire erosion will be low. The nutrient levels found by the end of the study period
were high enough to support the re-establishment of vegetation; however, the effect of alien herbivores on
broom seedlings could eventually lead to a progressive replacement of the legume scrubland in the burned area.
