The GrassSyn dataset: Soil organic carbon stocks in Brazilian grassy ecosystems. [PDF]

J Environ Qual
Abstract Although ecosystem management and restoration are known to enhance carbon storage, limited knowledge of ecosystem‐specific soil organic carbon (SOC) stocks and processes hinders the development of climate‐ready, biodiversity‐focused policies. Baseline SOC stocks data for specific ecosystems is essential.
