Time Your Spring Nitrogen Applications to Maximize Winter Wheat Yield
Carrie A.M. Laboski, Professor and Soil Fertility/Nutrient Management Specialist
Proper timing of spring N application can significantly increase winter wheat yield. To maximize yields, growers should try to apply N as soon as possible in the spring, taking into consideration soil physical conditions. Applying N when the ground is barely traffickable will likely result in rutting, compaction, and possibly yield loss if plants are damaged. One tactic to accomplish early N application might be to apply N in the morning before the top few inches of soil have re-thawed. Care should be taken to ensure that N does not run off the field before it has a chance to move into the soil.
