The advent of relatively inexpensive and accurate global positioning systems along with combine yield monitors has provided the opportunity for agricultural producers to instantaneously record and map crop yields while harvesting. Yield is the ultimate integrator of landscape and climatic variability and therefore should provide useful information for identifying management zones. However, due to year-to-year cli-
