Diffusion and convection controlled electrode reactions have been used to study a wide variety of agricultural heat and mass transfer problems. The paper reviews applications to the heat and mass transfer of plants in free and forced convection, the role of electrochemical simulation on the development of predictive models for soil‐atmosphere and soilcrop transfer and investigations of transfer in intermittent flow. Where field data are available they tend to confirm the validity of the technique. The biggest deficiency, noticeable particularly in intermittent flow around turbulence‐producing obstacles (vegetation, barriers), appears to be the fact that presently‐used models cannot deal adequately with two – and three – dimensional flow and sporadic boundary‐layer penetrations by irregular ‘events’. Electrochemiluminescent flow visualization may help in developing better qualitative and quantitative descriptions of such flows.
