State variables
Of all the additional variables many are accumulated values that can be used to create nitrogen and carbon balances together with the storage differences (see Figure 6.2 and Figure 6.3). Total balance check is the sum of the accumulated inflows and ouflows compared with the storage, and should optimally be zero.
