Abstract

Prior research on micronutrients fertilization for corn and soybean has been scarce in Iowa and has shown inconsistent yield responses. Therefore, the objective of a study conducted during 2012 and 2013 was to assess effects of boron (B), manganese (Mn), zinc (Zn), and their mixture on corn and soybean grain yield. Iowa State University has no interpretations of soil or tissue tests for micronutrients, other than for Zn in corn and sorghum.
