BECK’S Urea Topdress Study 2014 PFR Partners This study alters a grower’s normal nitrogen program by replacing the final sidedress nitrogen with a later V10 urea topdress treatment. The topdress urea treatment was applied with a Miller Condor dry fertilizer spreader. Urea topdress has become a popular method of applying nitrogen in some parts of Beck’s marketing area. Dry 46-0-0 urea is applied with a spinner truck over top of corn during the growing season. The advantages with this system are that it’s easy to apply and acres can be completed very quickly. The disadvantage with urea is its volatility— the loss of nitrogen as atmospheric gas when it converts to ammonia. Another concern is the possible crop injury from the urea prills landing on leaf tissue, causing leaf burn. All urea treatments were treated with Factor ® , a urease inhibitor distributed by Rosen’s.

Yield Response (Bu./A.) BECK’S Urea Topdress Study 2014 PFR Partners 15.0 10.0 Urea Yield Summary 13 Trial Locations Irrigated location 5.0 0.0 -5.0 -10.0 -1.65 Bu./A. yield loss 15% of Urea trials provided economic gains -$13.45 loss in net return per acre^ ^Net return based on $0.59/lb. N, $96.00/gal. Factor and $4.15/Bu. corn 2-year average = –3.18 Bu./A, -$12.59/A. Urea topdress applications resulted in average yield losses of 1.65 Bu./A., with net losses of $13.45/A. compared to the growers’ normal methods of sidedressing nitrogen. Only 15% of the topdress trials proved higher returns over PFR Partners’ usual programs. The red arrow indicates the highest yielding trial location in this study. It is interesting to note that it is also the only location under an irrigation pivot. As previously stated, one of the concerns with urea is that it is a surface-applied nitrogen application, unlike other programs that mechanically incorporate the nitrogen fertilizer into the soil. This surface application creates opportunity for volatilization—the loss of nitrogen into the atmosphere as it converts to ammonia. The irrigated trial location gave us the ability to use water as an incorporation method, thus preventing potential volatility. If this irrigated location is removed from the study to only compare non-irrigated sites, the average yield and return losses become –2.9 Bu./A. and - $18.38/A., respectively. This data is very comparable to the two-year average yield response of –3.18 Bu./A. with losses of -$12.59/A. Factor ® is a registered trademark of Midtech R&D and distributed by Rosen’s, Inc. 31
