• Developing a“4R Code of Practice”
• BMPs for all Forms of Nitrogen (4Rs)
• Nutrient Stewardship Recs
• Developing 4R Curriculum
• Roll-out in January, 2015
UNDER DEVELOPMENT
NREC serves as the foundation that for research and outreach programs that will lead Illinois agriculture into a new era.

N Rate Study Emphasis
N RATE STUDIES IN 2013
• 15 N Rate Trials (6 rates x 3 reps)
• 2 N Rate x Timing Trials (5 rates x 3 reps x 2 times)
• 5 VRT vs. Straight Rates
• 10 Split Application vs. One Application
• 1 Crop Canopy Sensor vs. Conventional
