- •
Absence of asymptotic behaviour indicated C accumulation did not approach an upper limit.
- •
Increases in OC accumulation were due to the accumulation of microbial detritus.
- •
Soil with lowest commencing OC concentration accumulated greatest mass of stable OC.
- •
Nutrients applied based on humus stoichiometry promoted OC stabilisation in soil.
- •
Environmental factors will determine equilibrium between C input in biomass and OM decomposition.
