We modelled the response of soil C and milk production to various drivers.
- class="label">•
The model was tested against eddy-covariance data with excellent agreement.
- class="label">•
Outcomes depended on C gain, grazing loss, soil C stability and decomposition rates.

There were trade-offs between C use for grazing and SOC formation.

Increasing soil C is difficult because both soil C and milk production need C.
