Several plant nutrients are referred to as micronutrients because very small amounts are needed. Prior research in Iowa and neighboring states showed inconsistent corn and soybean grain yield responses to micronutrient applications, except for zinc in corn. This report summarizes results of two studies with corn and soybean, one with application to the soil and the other with application to foliage, which were conducted from 2012 through 2014. The micronutrients evaluated were boron (B), copper (Cu), manganese (Mn), and zinc (Zn).
