UNL releases updated nitrogen calculator for corn growers

LINCOLN —For the past 50 years, the University of Nebraska- Lincoln’s nitrogen application calculator has been used by producers to calculate the appropriate amount of nitrogen to apply to their corn crop fields. The calculator aims to help producers understand the 4Rs system when using nitrogen. The 4 Rs include Right source, Right rate, Right placement, and Right timing. These 4Rs work together and are adjusted based on the producer’s choices.
