Before removing straw from the field, it is important for farmers to understand the nutrient value. 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. In previous newsletters, we reported that typically a ton of wheat straw contains approximately 11 pounds of N, 3.7 pounds of P2O5, and 29 pounds of K2O. According to the 2024 Second Quarter Fertilizer Prices Across Ohio bulletin (https://u.osu.edu/ohioagmanager/2024/04/15/2024-second-quarter-fertilizer-prices-across-ohio/) and nutrient removal “book values”, one ton of wheat straw would remove approximately $14.12 of P2O5 & K2O.
