Short summary

We compare the carbon budget of a pasture using two different system boundaries: including and excluding grazing cows. We reveal the importance of non-CO₂ fluxes as budget components depending on the chosen system boundaries and discuss the effect of their uncertainties. Budget components were directly measured or derived from cow related measured parameters like milk yield. The resulting carbon budgets of both approaches agree within the limits of uncertainty showing a near-neutral behavior.
