Soil biological activities of a temperate forests in altitudinal transect of Conguillío National Park (38° S), Chile
In Chile there are few studies describing the biological activities and soil nutrient dynamics in high mountain areas, therefore sensitive parameters able to express what happens in these ecosystems are required. The aim of this study was to determine soil biological properties through biochemical v...

In Chile there are few studies describing the biological activities and soil nutrient dynamics in high mountain areas, therefore sensitive parameters able to express what happens in these ecosystems are required. The aim of this study was to determine soil biological properties through biochemical variables: fluorescein diacetate hydrolysis, carbon and nitrogen microbial biomass, β-glucosidase, carboximethylcellulase, acid phosphatase, urease and arylsulfatase; and chemical characteristics of soil in an altitudinal transect in Conguillío National Park (38º S), Chile.
