GF-2017 Demonstrates Value in Large Scale Iowa Trials.

Nitrogen loss endangers water supplies and is an inefficient use of input dollars. Nitrogen stabilizers, however, can maintain nitrogen in a form not subject to leaching or denitrification for several weeks after an application. Use of anhydrous ammonia plus   N-Serve® nitrogen stabilizer has been an accepted practice to minimize nitrogen loss for more than three decades. Unfortunately, a similar nitrogen management strategy has not been readily available to growers who use UAN (urea ammonium nitrate) as their source of nitrogen. GF-2017 is a new formulation of nitrapyrin which enables stabilization of liquid nitrogen and was field tested in large-scale trials throughout Iowa under a Special Local Needs permit in 2008. These thirty-two (32) large scale trials demonstrate the ability of GF-2017 to provide a consistent yield advantage over UAN alone across various cultural practices, yet a greater yield benefit was observed when GF-2017 was used with corn following corn, in no-till corn and when incorporated by rainfall. To be an effective stabilizer in a liquid fertilizer program, GF-2017 needs to be surface stable and be able to be incorporated by rainfall.  GF-2017 provided both attributes while delivering a consistent yield advantage across the rainfall incorporation timings observed.
