The objectives of the project reported in this fact sheet were to 1) examine current post-alfalfa N fertilizer credit guidelines and investigate the potential to further reduce N fertilizer rates (if possible) on first year corn after alfalfa across Utah, and 2) accordingly update the USU Extension corn management recommendations and promote grower awareness and adoption of the new guidelines.
