Soil andic properties as powerful factors explaining deep soil organic carbon stocks distribution: the case of a coffee agroforestry plantation on Andosols in Costa Rica [PDF]

open access: yes, 2019
Abstract. Soil organic carbon (SOC) constitutes the largest terrestrial carbon stock. Both distribution and variation of SOC stocks are needed to constitute reference baseline for studies on temporal SOC change. Specifically, in volcanic areas, the spatial variation of soil andic properties usually explains the spatial variation of topsoil SOC contents,
