in the "rest" ecosystem section the above and understory and root mortality needs to check to make sure there is veg c accum, otherwise do not apply it. for now, make sure the input file has zero mortality for the appropriate land categories
but the understory needs to be fixed. the assumption is that the soil c accum is the net exchange and the veg components remain the same if there is noveg c accum
soil carbon gain has to be matched by subtractions from roots (mortality) and litter
