Carbon, Nitrogen and Phosphorus Cycling in Forest Soils

---

Physicochemical and biotic factors influence the binding and dispersivity of soil particles,
and thus control soil macroaggregate formation and stability. Although soil pH influences dispersivity,
it is usually relatively constant within a site, and thus not considered a driver of aggregation dynamics.
However, land-use change that results in shifts in tree-species composition can result in alteration of
soil pH, owing to species-specific traits, e.g., support of nitrogen fixation and Al accumulation. In a
long-term, randomized complete block experiment in which climate, soil type, and previous land-use
history were similar, we evaluated effects of individual native tropical tree species on water-stable
macroaggregate size distributions in an Oxisol. We conducted this study at La Selva Biological
Station in Costa Rica, in six vegetation types: 25-year-old plantations of four tree species grown in
monodominant stands; an unplanted Control; and an adjacent mature forest.
