Short-range-order minerals as powerful factors explaining deep soil organic carbon stock distribution: The case of a coffee agroforestry plantation on Andosols in Costa Rica

Chevallier Tiphaine , Fujisaki Kenji , Roupsard Olivier , Guidat Florian , Kinoshita Rintaro , Filho Elias de Melo Viginio , Lehner Peter , Albrecht Alain

… Soil organic carbon (SOC) constitutes the largest terrestrial C stock, particularly in the Andosols of volcanic areas. … The spatial variation of soil short-range-order minerals such as allophane usually explains the variability of topsoil SOC contents, but SOC data for deeper soil layers are needed. … We found that within a 1 km2 Costa Rican basin covered by coffee agroforestry, SOC stocks in the upper 200 cm of soil were highly variable (24 to 72 kgCm-2). …
