3-Year Data on the Rate of Nitrogen that Maximizes Profitability

Three-year evaluation of the economic optimum nitrogen rate (EONR), or the rate of nitrogen (N) that maximizes profitability. Prior to planting, anhydrous ammonia was applied to meet the total amount of N for each treatment.

"Why would anhydrous ammonia pre-plant, subjected to all of the abundant and heavy rainfall events, be able to produce such high yields on a year like this?

  • Ammonium N does not leach.
  • Ammonium N cannot be lost to the air via denitrification.
  • Anhydrous ammonia vitrifies somewhat slower than the other fertilizer materials.
  • Natural soil conditions that inhibit nitrification of ammonium (cold, wetness, strong acidity).
  • The conversion to nitrate N (prone to leaching) requires oxygen and does not take place in a very wet soil."

Beck's Hybrids PFR program conducts more than 75 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.
