Questions exist on how producers can use GPS technology in strategically managing farm operations and be profitable.
In 2004 and 2005, eleven workshops on GPS Technology in Agriculture were conducted. Iowa State University (ISU) Extension field specialists provided answers to how differential corrections can make GPS more reliable and accurate, how to set up GPS for yield monitoring and mapping, GPS system setup costs including Real Time Differential Correction, and advanced self guidance systems. A total of 154 participants attended these sessions over two years.
A sample survey of 33 participants showed an average farm size of 973 acres. These participants valued the information presented at $1.82 per acre or $1,771 per farming operation. Surveyed participants 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 70 percent increase in their level of knowledge on GPS system setup costs including Real Time Differential Correction and Economics of GPS. All responses indicated an average 50 percent increase in their level of knowledge for how to set up GPS for yield monitoring and mapping.
