Short summary
Tropical rain forest are likely to grow more, and produce more litterfall, as a result of increasing temperature and carbon dioxide. We experimentally doubled litterfall in large plots in forest in Panama; there were also removal plots. After 6 years of continuously adding litter, we found that soil organic matter and many plant-available nutrients were increased down to as far as 30 cm into the soil. This increase in organic carbon in the soil reduces the carbon dioxide in the atmosphere.
