To help with the evaluation of ideas put forward in this and related
publications [e.g. 15], the writer is creating a computer package for coarsely
predicting the performance of lesser-known plants by the empirical method
(Level C). Called PLANTGRO and written in BASIC, the package provides
simple methods for creating plant, soil, and climate data-files and enables
one to make predictions for any plant-soil-climate combination for which
one has made or has acquired data-files.
