Title:
Can Preplant Fertilization of Small Grains be Eliminated, 2008
Author:

Journal:
Forage and Grain: A College of Agriculture and Life Sciences Report
Abstract:
The results of this study support the practice of not applying nitrogen at planting time even if the soil N level is low. Highest yields were obtained if the nitrogen that would have been applied at planting time was applied at the 5-leaf stage in addition to the N that would normally be applied at this time. If the preplant N application is skipped, the crop nitrogen status must be monitored carefully and N fertilizer should be applied by the 5-leaf stage to avoid a yield reduction. If a large amount of N is applied at the 5-leaf stage, lodging may be encouraged.
