I'm not sure why, but the CN model has much lower microbial biomass turnover rates, which leads to larger MIC pools and smaller SOM stocks, compared to the C-only version of the model, even when using the same parameter file.

Below are to plots of MICr pool sizes for the CN and C-only model (left and right respectively).

I'm assuming this feature is being caused by this line, which adds the density dependent exponent term (currently set to 2) to the calculation of microbial turnover:

@EmilyKykerSnowman, maybe this is worth discussing if we keep this in?
