Global Positioning Systems (GPS), along with yield monitors, are considered by producers as tools for enhanced production. Concerns do exist on how GPS works, what different applications it can be used for, variations in different GPS kits available in the market, and advanced GPS applications.
Iowa State University Extension delivered a workshop on GPS Technology in Agriculture in December 2003. Extension provided answers to how Differential GPS works, how to divide fields into zones, how to set up GPS for yield monitoring and mapping, basic GPS systems setup and costs, GPS use in variable rate technology, and advanced self guidance systems. A total of 61 participants attended this session.
A total of 37 evaluation responses were received. Respondents provided a pre- and post-workshop level of knowledge in their evaluations. Percent increase in level of knowledge was assessed based on pre-workshop level. All respondents indicated an average 90 percent increase in their level of knowledge on how Differential GPS works. All responses indicated an average 70 percent increase in their level of knowledge for how to divide fields into zones, how to set up GPS for yield monitoring and mapping, GPS applications in advanced self guidance systems, and remote sensing. The responding participants also indicated an average 65 percent increase in their level of knowledge for basic GPS systems setup and costs and use of GPS in variable rate technology application. All respondents indicated that the information presented was useful to their operation.
