We evaluated the current
status and the future projection of soil organic carbon (SOC) storage in
Japanese croplands (paddy and upland), using a soil carbon turnover model. The
model based on the RothC involves the modification after verification of
turnover processes of SOC for the main soil type in Japan, Andosols. The objectives of
this study are to i) evaluate the spatial distribution of SOC storage, ii)
estimate the annual input organic matter for reaching the equilibrium, and iii)
simulate time changes of SOC storage with changing agricultural practices as
well as climate conditions.
