Corn and Soybean Yield Response to Micronutrients

Authors: , , , ,


Micronutrients are essential for crop growth, although they are needed in very small amounts. Prior research in Iowa and neighboring states had shown inconsistent corn and soybean grain yield responses to fertilization with micronutrients, 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, conducted at this farm from 2012 through 2014. The micronutrients evaluated were boron (B), copper (Cu), manganese (Mn), and zinc (Zn).
