Do we have any wheat left in Ohio? I would like to see more acres. It makes our other two crops better and reduces weed, insect and disease problems for them, too. The new Ohio Agronomy Guide has just a bit of an update on spring nitrogen (N) recommendations for wheat in Ohio.
We still suggest following the Tri-State Fertilizer Recommendations for N rates in wheat, with an update on the discussion of why. We do rely on yield potential of a field to make the recommendation. Once you have set a realistic yield goal, the recommendation may be based on the following table. These recommendations are for mineral soils with adequate drainage and 1% to 5% organic matter.
Nitrogen rate for wheat by yield potential.
Total N rate
We do not give any credit for the previous soybean or cover crop, since we do not know if that organic N source will be mineralized for the wheat crop. The recommendation does suggest that you subtract from the total (spring N) any fall applied N up to 20 pounds of N per A.
