ESN Replaces Multiple Applications

An Idaho study compared ESN applied at emergence or at planting with conventional urea in multiple applications. A single ESN application at emergence or at planting produced yields similar to or greater than multiple applications of urea. Split urea application is 50% of nitrogen (N) at emergence & 50% in three applications in season. ESN was broadcast and incorporated. The 100% rate is 200 lbs N/acre. Fewer applications means savings of time, fuel, labor and equipment, saving the grower money while growing high yielding, high quality potato crops. ESN is indeed a more efficient nitrogen fertilizer.

Minnesota study compared ESN applied at emergence or at planting with multiple applications of conventional urea. As in the Idaho study, a single ESN application at emergence or at planting produced yields similar to or greater than multiple applications of urea. Split urea application included 100 lbs N/ac at emergence, 20 lbs N/ac at hilling, and four post-hilling applications of 20 lbs N/ac at approximately 2 week intervals. ESN was broadcast and incorporated. N rate shown includes 40 lbs N/acre at planting from DAP. Fewer applications means savings of time, fuel, labor and equipment, saving the grower money while growing high yielding, high quality potato crops. ESN is a smarter nitrogen fertilizer.
