Large differences in CO emissions from two dairy farms on a drained peatland driven by contrasting respiration rates during seasonal dry conditions.

Drained peatlands are major sources of CO to the atmosphere, yet the effects of land management and hydrological extremes have been little-studied at spatial scales relevant to agricultural enterprises. We measured fluxes of CO using the eddy covariance (EC) technique at two adjacent dairy farms on a drained peatland in Aotearoa New Zealand with remaining peat depths 5.5-8 m.
