           Site-specific crop/soil management technologies have been available for over fifteen years. Consequently, there is a demand for classroom and laboratory education across a variety of agricultural disciplines in the University community. To meet this demand, a course was developed in 1998 to teach the basic concepts of site-specific crop/soil management. This class is designed as a upper level undergraduate and graduate class and generally has between 10 and 20 students. The students typically come from agricultural engineering, agronomy, weed science, and entomology/plant pathology majors and are evenly split between undergraduates and graduates. The class is not required by any curriculum but is considered a “restricted elective” by many in the College of Agriculture. The class is designed in a lecture/lab format with two one-hour lectures and an independent laboratory. As the students generally come from various diverse backgrounds and experiences, the lectures begin with the basic concepts of global positioning systems (GPS) and geographical information systems (GIS) and proceed through explanations of coordinate systems, projections, variability, soil sampling methodology, remote sensing, etc. The laboratories are designed to be done independently (either alone or with a group) and include navigating with a GPS unit, finding and using data available from the internet, developing sampling schemes, displaying and using yield data, etc. Most of the laboratories center on increasing the students GIS skills, hence, as the laboratories progress, they get increasingly more difficult. The class culminates with a semester project, done by groups, where each group must give a presentation of a case study involving a site-specific project. The instructor will provide field data which the groups must interpret and make site-specific recommendations for a predetermined objective. End-of-semester evaluations have shown this approach is well received by the students and most indicate they have learned a great deal.
