[1] We characterized the effect of large-scale (>20 mm) soil physical structure on the age and recalcitrance of soil organic carbon (SOC) in upper (A) and lower (B) horizons of grassland soils from California’s Central Valley. The radiocarbon content of SOC from surfaces and interiors of large-scale soil structural units (‘‘peds’’) was measured in order to characterize the spatial distribution of soil C pools with distinct residence times. The radiocarbon content of CO2 released following… CONTINUE READING
