    Nutrient Value of Wheat Straw

    Author(s): Laura Lindsey , Author(s): Eric Richer, CCA , Author(s): Ed Lentz, CCA

    Before removing straw from the field, it is important for farmers to understand the nutrient value. Though we have seen some softening of the 2022 fertilizer prices, P and K fertilizer prices remain higher than normal. The nutrient value of wheat straw is influenced by several factors including weather, variety, and cultural practices. Thus, the most accurate values require sending a sample of the straw to an analytical laboratory. However, “book values” can be used to estimate the nutrient value of wheat straw.

    When and How Much Nitrogen to Apply to Wheat

    Author(s): Ed Lentz, CCA , Author(s): Laura Lindsey

    Wheat has already reached green-up across the state so spring N may be applied anytime fields are fit. Keep in mind that research has shown no yield benefit to early N applications as long as the application was made by Feekes GS 6 (one visible node).

  3. Nitrogen Application Timing for Weak Wheat Stands

    Author(s): Ed Lentz, CCA

    Late-planted wheat fields had little opportunity for growth before cold and wet conditions moved into the area last November. Fall tiller production was limited because of early cold weather soon after planting. In addition, some wheat stands have been damaged this winter from lack of snow cover, standing water, saturated soils, ice sheets, and days of very cold temperatures.

  4. Topdressing Wheat with Liquid Swine Manure

    Author(s): Glen Arnold, CCA

    Wheat fields will begin to firm up in Ohio and the topdressing with nitrogen fertilizer will soon start. There is usually a window of time, typically around the last week of March or the first week of April, when wheat fields are firm enough to support manure application equipment. By this date, wheat fields have broken dormancy and are actively pulling moisture and nutrients from the soil. With the limited fall and winter opportunities to apply manure to fields, many livestock farms have more manure than usual for this time of year.

  5. Nitrogen Rate Recommendations for Wheat - 2018

    Author(s): Ed Lentz, CCA , Author(s): Laura Lindsey , Author(s): Steve Culman

    Wheat has already reached green-up across the state so spring N may be applied anytime fields are fit. Keep in mind that research has shown no yield reduction for N applications before Feekes GS 7 (two visible nodes). However, wheat is growing slow because of the cool temperatures. Nitrogen applied early has the potential to be lost since wheat will use little N until after jointing. Urea-ammonium nitrate (UAN) or 28% has the greatest potential for loss and ammonium sulfate the least. Urea will have little potential for loss as long as it does not volatize.
