2005 Workshop Objectives

1. To share ideas and concepts relative to improved NUE for corn production.

2. To delineate the components needed within functional algorithms that employ active sensors.

3. To discuss the current regional project and identify improvements needed for conducting future collaborative sensor-based research.

4.  To develop agronomic relationships between active sensors and N management for other crops.
