Scant attention has been given to the evaluation of the magnitude of the net CO2 balance from turf despite the fact that approximately 41% of the total urban area in the continental US is dedicated to residential use. Most of that area is dominated by turf and continues to expand. This corresponds to more than three times the area of irrigated planted corn. This study reports on the evaluation of the net carbon balance at a commercial sod farm over a three-year period. Data was collected using the eddy-covariance method and CO2 fluxes subsequently calculated. Preliminary results suggest an annual net CO2 sink for an intensively managed sod farm.
