In-season decision support tools for estimating sidedress nitrogen rates for corn in the Mid-Atlantic Coastal Plain

In corn (Zea mays L.) production, determining appropriate nitrogen (N) rates is a critical part of achieving profitable yields, while minimizing negative environmental effects. Many tools to assist in the determination of optimum corn sidedress N rates exist, however, those that are low cost, that can be used in real time and that do not require extensive scouting or sampling may be preferred. This study compared the rates prescribed by four...
