Description

The importance of micronutrients for production of a variety of crops in the North-Central region of the U.S. has been recognized for many years. When needed, these essential nutrients can have a substantial positive impact on production. However, neither the need for nor the importance of each micronutrient is universal across the region. Importance (need) is greatly affected by crop, soil properties, and production environment. With traditional thinking over the years, thoughts have focused on band, broadcast, or foliar applications. There are always questions about source and rate. There are, however, some new questions and ideas about the use of micronutrients in fertilizer programs for modern crop production. In contrast to concerns about management of nitrogen, phosphate, and potash in various production environments, micronutrient management has not recently been the focus of many soil fertility research programs.
