Sponsored: Is Split Applying Nitrogen Always the Best Risk Management Strategy?
With this 5-year study we evaluate various nitrogen (N) application timings and their affects on N use efficiency, N loss, and yield. Each treatment in this study received a total of 180 lb./A. of N.
Late season N availability is one key to successful high-yielding corn production. Nitrogen demand is high in the reproductive stages of growth.
“Historically, 2x2 followed by sidedress at the V3 growth stage has provided the highest net returns. However, in 2015, utilizing UAN one half up front followed by the other half at sidedress achieved the greatest return on investment (ROI). Regardless of the form of N used, they can all be managed effectively for high yields and ROI. From my experience, split applying, regardless of the product used, is the best risk management strategy,” says Steve Gauck, Beck’s Field Agronomist.
Beck's Hybrids PFR program conducts more than 100 different studies across multiple locations (500+ acres) to learn how different management practices and new technologies perform in field environments. Simply put, it is research focused with the farmer in mind.
