Resumen
Descripción
The availability of nitrogen and phosphorus may limit rates of regrowth of secondary forests in Amazonia. The highly weathered soils are nutrient poor, and numerous cycles of slash and burn can further impoverish nutrient stocks and lead to site degradation. The mineralization of N and P from soil and litter by enzymatic activity and the acquisition of nutrients by mycorrhizae could be important for the recuperation of nutrient cycles during secondary forest succession.
