Soils are the largest non-fossil terrestrial reservoir of organic carbon on Earth, and tropical soils contain about one third of this pool (Beinroth et al., 1996). Tropical sols have the potential to augment carbon sequestration by management strategies that allows them to revert to their original organic carbon levels, thus mitigating global warming.

This project proposes and evaluates a methodology for managing tropical watersheds and their potential for sequestering organic carbon by using highly productive biomass crops such as environmental cane (Saccharum spontaneum), vetiver grass (Vetiveria zizaniodes) or Napier grass (Pennisetum purpureum) that serve as solar energy scavengers, benefiting from enhanced CO2 atmosphere.

This project evaluates and compares management strategies for soil carbon sequestration in the Ro Grande de Arecibo watershed (RGA) located in north central Puerto Rico that is also an important water supply basin for the metropolitan area of San Juan, Puerto Rico.
