Effect of scarification on soil change and establishment of and artificial forest regeneration under Nothofagus spp. in Southern Chile
Soil scarification has been used as a silvicultura method to facilitate the regeneration of some forests, but it may have a negative impact on the properties of the soil. We evaluated the effect of a mechanized scarification on a volcanic soil after a shelterwood cutting in a Nothofagus spp. forest,...
