Soil organic matter
s: solid phase
g: gas phase
w: aqueous phase
Single point simulation at Harvard forest
Model dynamics: Two microbial communities, compete for DOC and inorganic N (NI), coupled with plants and full CN chemistry
The input was done on Apr.1st, Jun. 1st, Aug. 1stand Oct. 1st in the first model year. All simulations start with identical initial conditions.
Unit: mol CO2
Changes in Microbial biomass
Unit: mol C m-3 soil
Changes in litter degradation
Unit: mol C m-3 soil s-1
Microbial activity: fraction of active microbes
Immobile: no vertical movement of DOC allowed
Mobile: DOC is free to move vertically
