Hard red spring wheat (DNS) will be planted on many farms in the not-to-distant future. The nitrogen requirement for 14% protein is 3.5 pounds per bushel of expected yield. If you expect to produce a 30 bushel per acre crop, then the total nitrogen supply should be at least 105 pounds per acre. The total nitrogen supply is nitrogen you apply as fertilizer plus the quantity in soil. Overwinter precipitation has saturated upper layers of the soil in your field and will move, or is moving, nitrogen to lower depths. Make sure you have approximately 30 pounds of nitrogen in the top foot. If you have enough nitrogen in the soil (105 pounds or more for a 30 bushel/acre crop), but only have 10 pounds in the top-foot, then an application of 20 pounds per acre is warranted.
