Soil Moisture Monitoring Variable Rate Irrigation As-Applied Water WUE (bu/inch)
Delivering Results 3 bu/a increase in yield 70% win ratio Rx 0.11 inches more water (-0.40 to +0.50) 0.34 inches more applied water (-3.0 to +3.7)
Variable Rate Seeding Corn field research has documented the value of: Optimizing Seeding Rate per Yield level
