BECK’S Nitrogen Rate Studies<br />
2014 PFR Partners<br />
“Hitting the Bullseye”<br />
Through this year’s intensive nitrogen research studies, Beck’s CIL PFR team tried to<br />
evaluate the percentage of growers that were using economic optimum nitrogen rates.<br />
The following is a summary of multiple locations where growers’ normal nitrogen rate<br />
programs were compared to either decreasing their total rate by 30 lb./A. or increasing<br />
the total rate by +30 lb./A. and +60 lb./A. This additional nitrogen was sidedressed<br />
either early with the grower’s normal program or at growth stage V10 with our lateseason<br />
programs. The summary analyzes the higher and lower nitrogen rates at each<br />
timing as well as all of the trials together.<br />
Growers with correct nitrogen rate = 35%<br />
Growers with wrong nitrogen rate = 65%<br />
This year’s results indicated that 35% of our PFR Partners were indeed implementing<br />
economic optimum nitrogen rates. When these growers adjusted their normal rate<br />
programs, no economic gains were incurred.<br />
As far as the other 65% are concerned, they did experience economic returns higher<br />
than their current nitrogen program by increasing or decreasing their total nitrogen rate.<br />
Interestingly enough, 39% of those growers could have applied less nitrogen, and 61%<br />
of them needed to apply more.<br />
Simply put, 65% of our PFR Partners were using the wrong rate of nitrogen.<br />
