Previous Iowa research has assessed the corn and soybean grain yield 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 evaluated postemergence sidedressing K fertilizer, although postemergence nitrogen sidedressing for corn is a common practice. Therefore, a study was initiated at this farm in 2017 to evaluate the value of sidedressed liquid K fertilizer for corn and soybean grown in rotation.
