Short summary
We used measurements of radiocarbon to model the decomposition of organic matter associated with minerals in tropical rainforest soils, using contemporary and archived samples. Most organic matter decomposed over 11 to 26 years, while a smaller portion decomposed over centuries. Rates were similar among soils with strongly differing physical and chemical properties, but declined with a proxy for oxygen limitation. Previous models based on one time point may underestimate decomposition rates.
