1. Integrating Management Zones and Canopy Sensing for Improved Nitrogen Recommendation Algorithms Active crop canopy sensors have been studied as a tool to direct spatially variable nitrogen (N) fertilizer applications in maize, with the goal of increasing the synchrony between N supply and crop demand and thus improving N use efficiency (NUE). However, N recommendation algorithms have often proven inaccurate in certain subfield regions due to local spatial variability. Modifying these algorithms by integrating soil-based management zones (MZ) may improve their accuracy... J. Crowther, J. Parrish, R. Ferguson, J. Luck, K. Glewen, T. Shaver, D. Krull, L. Thompson, N.

2. Comparison of Ground-Based Active Crop Canopy Sensor and Aerial Passive Crop Canopy Sensor for In-Season Nitrogen Management Crop canopy sensors represent one tool available to help calculate a reactive in-season nitrogen (N) application rate in corn. When utilizing such systems, corn growers must decide between using active versus passive crop canopy sensors. The objectives of this study was to 1) determine the correlation between N management by remote sensing using a passive sensor and N management using proximal sensing with an active sensors. Treatments were arranged as field length strips in a randomized complete... J. Parrish, R. Ferguson, J. Luck, K. Glewen, L. Thompson, B. Krienke, N. Mueller, T. Ingram, D. Krull, J. Crowther, T.

3. Sensor-Based Fertigation Management for Production-Scale Applications Fertigation, the practice of applying fertilizer through irrigation water, offers many benefits as an in-season nitrogen application technique for irrigated corn production systems. Most notably, fertigation offers growers the opportunity to make multiple applications throughout the growing season, including late season applications during corn reproductive growth stages. Growers have traditionally determined the timing and number of fertigation applications using visual observations, irrigation... J. Stansell
