Abstract:Measurements of mass transfer coefficients were made directly by the use of point and line sources. The gas used was propane. The studies revealed that the form of the profile of mass transfer coefficients was markedly dependent on crop geometry, with a local maximum and minimum within the crop canopy. Further studies demonstrated the anisotropy of mass transfer coefficients above the crop canopy wherein the downwind component was greater than the crosswind component. Crosswind and vertical components were nearly equal. Studies were also made on energy balances within crops and with individual plant leaves.
