Leaf Litter Decomposition and Mulch Performance from Mixed and Monospecific Plantations of Native Tree Species in Costa Rica

background

This research looks at leaf litter decomposition rates and mulch performance of four native tree species in mixed and monospecific plantations at the La Selva Biological Station in Costa Rica. The four species considered were Callophylum brasiliense, Jacaranda copaia, Vochysia guatemalensis, and Strypnodendron microstachyum. The faster the decomposition, the faster the nutrient transfer from the trees into the soils for uptake by other trees or by crops when the leaves are used as mulch.
