A method and system for evaluating crop performance obtains weather data for
defined
geographic locations within a geographic area. Historic soil data is obtained for
the defined geographic locations within a geographic area. Historic yield data
is obtained for the defined geographic area for a representative crop. Predictive
data nodes are determined based on at least one of the obtained weather data, the
historic soil data, and the historic yield data. Each node is associated with a
certain range of average yields for a particular crop.
