Muscatine Island Farm
Micronutrients are essential for crop growth, but prior research in Iowa and neighboring states has shown inconsistent grain yield responses to fertilization except for Zn in corn. In 2013, we summarized two years of research at this farm that evaluated effects of boron (B), manganese (Mn), and zinc (Zn) application on corn and soybean yields. In this report, we combine those results with additional research conducted in 2014.
