Soil total exchangeable bases
Webtotal potential acidity of the soils varied from 29.43-61.32 cmol(p +)/kg. It was apparent that the total potential acidity in most of the soils, decreased with the depth of soils (Figure 1). This might be due to the deposition of exchangeable bases with increasing soil depth. The higher values of the total potential acidity WebLocation: Neotropics. Methods: We used data from 26 sites, 201 1-ha plots and >92,000 trees distributed across the Neotropics. We quantified for each site water availability and soil total exchangeable bases and for each plot three key community-weighted mean functional traits that are important for biomass stocks and productivity.
