ISU Extension, the Iowa Corn/Soybean Initiative, ISU Research and Demonstration farms and the NW Iowa Experimental Association partnered together to form the Northwest Iowa On-farm Research project which is now in its 5th year in Lyon, Sioux and Osceola Counties in the NW corner of Iowa. The goals of this project are to implement on-farm research projects that are beneficial to the cooperator and other NW Iowa farmers; to cooperate with producers to provide up-to-date research that affects their operation; and to provide unbiased, statistically analyzed data for farmers on compared production practices. We want to answer the crop production questions they have using replicated randomized studies. We strive to make these projects simple, informative and practical for our cooperators. During the past two years additional cooperators have been added in Buena Vista, and Sac counties in NW Iowa.
