Evaporation from rain drops on leaves in a cereal canopy: A simulation model

  • D. R. Butler
Article

Abstract

In crop canopies, the persistence of discrete water drops on leaves after rain is of particular importance to the epidemiology of certain foliar pathogens. A model is described which simulates the heat and water vapour fluxes in a plant canopy and includes evaporation from water drops on the leaves. Energy balance equations allow for heat conducted to drops from the adjacent leaf tissue. Preliminary field tests of model performance for winter wheat, which compare predicted and visually assessed leaf wetness, are encouraging.
