Summary
The definition of the word instrument is stretched to include use of a leaf-environment model to aid in monitoring leaf status in the field. A set of equations that couple photosynthesis, stomatal conductance, the leaf energy balance, and leaf and soil water status are briefly described for a typical C3 plant. The Basic language code for these equations, which was developed on a Radio Shack, Model 100 microcomputer, is included with documentation including input and output values of all important variables along with a sample session. Some representative output from the model is discussed along with limitations of the equations.
