It is recognized that both the location and the fraction of the soil surface exposed tosunlight change to some degree with the time of day and depending on row orientation. Theprocedure presented here predicts a general averaged fraction of the soil surface from which themajority of evaporation occurs. Diffusive evaporation from the soil beneath the crop canopy isassumed to be largely included in the basal Kcb coefficient.
