1. Impact of Site-Specific Variability on the Effectiveness of Active Canopy Sensors for In-Season N Management in Corn

In-season nitrogen (N) management in corn guided by active canopy sensors is often associated with higher yields, profit and nitrogen use efficiency (NUE). However, these benefits could vary from field-to-field and year-to-year. These inconsistent relationships between technology and benefits represent a major challenge for increasing adoption of sensor-based N application in corn. Thus, a better understanding of which site-specific factors determine positive benefits from sensor-based N application... L. Puntel, J. Luck, L. Thompson
