- •
Century model perform well, but underestimates carbon stocks in sub-tropical soils.
- •
Soil texture affects more the simulation bias of Century than soil types.
- •
The simulation bias was greater for sandy compared to clay soils.
- •
The effect of silt + clay content on soil carbon storage was non-linear.
