Abstract
Extensive research in Iowa has assessed the corn and soybean response to different potassium (K) fertilizer placement methods using granulated potash fertilizer (0-0-62), including a long-term experiment at this farm. However, no study had evaluated sidedressing K fertilizer for corn or soybean, although postemergence nitrogen sidedressing for corn is a common practice. Therefore, a study was initiated at the ISU Northeast Research Farm, Nashua, in 2017 to evaluate the value of sidedressed liquid K fertilizer for cornsoybean rotations.
