Field experiments of CO 2 release from a line source left many gaps in our knowledge of CO 2 diffusion and how the released gas was lost from the field. The two dimensional vertical flux and horizontal mass flow numedical model presented here showed graphically where and how this loss was occurring. CO 2 tended to be lost vertically in a bent‐over plume. Some of the CO 2 which was lost vertically would diffuse again into the crop canopy, but this small amount would not increase the canopy CO 2 concentration significantly.
