Descripción
Increasing research has focused on mixed forest, found strong shreds of evidence that on ecosystem services provided by this stand over than pure forest. However, the studies to understand the relationship between soil nutrients, such as phosphorus -P-, and the effect of the type of forest are still deficient. It is widely known that P is an essential element for life and vegetation growth, despite that, its availability is limited in natural ecosystems. To this end, the superficial soil horizon was studied within three experimental triplets located in the Cantabrian Mountains and the Pyrenees. This research aimed to assess whether oak-pine (Quercus sp. and Pinus sylvestris) mixed forests influence differently than pure ones on the state and availability of soil phosphorus. Organic P, inorganic P, as well as P in soil microbial biomass phosphorus and enzymatic phosphatase activity were measured in 39 samples. Both chemical and biological variables were analyzed using the linear mixed two-factor method. Results suggested that the pH and location are the critical factors to determine P behavior. On the other hand, mixed forest stands showed an increase in their enzymatic activity, so we can conclude that species interaction is important for nutrient transformation.Keywords: Adaptive and integrated management, Climate change, Sustainable Forest management, Deforestation and forest degradation, Biodiversity conservationID: 3486443
