Southeast Research and Demonstration Farm
The Iowa Crop Performance Tests (ICPT) are conducted each year to provide information farmers need to select the best varieties or hybrids for their production conditions. The Southeast Research Farm (SERF) has hosted these soybean experiments each year since 2005, and two corn experiments since 2009. This information and more can be downloaded from www.croptesting.iastate.edu.
