One of the newest technologies in precision agriculture is automatic section control on application equipment. This technology has tremendous potential to reduce wasted inputs, especially on irregularly shaped fields. Paybacks are not necessarily as great on rectangular fields. Producers considering adoption of the technology need to decide whether they will receive sufficient payback for their field shapes. They must also decide what resolution of control on the boom is necessary. Researchers have developed analytical tools that can be used to evaluate the potential of the technology on particular fields. This paper will describe these tools and show how they can be used to make decisions about adoption of the technology.
