ESN Increases Potato Profits

Results from field studies are clear that ESN is a smarter nitrogen fertilizer for potatoes. ESN increases yields while saving money by eliminating multiple nitrogen applications. This means more money in the grower’s pocket. An Idaho study compared ESN applied at emergence or at planting with conventional urea in multiple applications. The greatest gross and net crop value were obtained with ESN. Gross and net crop value were calculated from yield and quality data obtained in replicated plot studies. Split urea application is 50% of 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 may cost a little more, but puts more money in the grower’s pocket. That’s what makes ESN the Smart Nitrogen fertilizer.

The results of this Minnesota study show once again why ESN is the Smart Nitrogen. The study compared ESN applied at emergence or at planting with multiple applications of conventional urea. The greatest net returns were obtained by using a single application of ESN. 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. ESN saves time, fuel, labor and equipment, while growing high-yielding, high-quality potato crops. ESN may cost a little more, but puts a lot more on the bottom line. ESN is Smart Nitrogen. Shouldn’t every potato grower be using ESN?
