Interpretive Summary:

Technical Abstract: The Texas High Plains, although a semiarid region, produces approximately 9 million cubic meters (7500 acre-feet) of runoff from feedlots per year. A field experiment was conducted to evaluate the application of feedlot runoff (effluent) to wheat (Triticum aestivum, awnless variety). Feedlot effluent was applied to 18 plots of wheat at the USDA-ARS at Bushland, TX. Treatments of effluent were application rates 0, 25, and 50 cm/yr. Dry matter yield increased with effluent application rates, however, none of the mean dry matter yields were statistically different. Mean dry matter yields were 3146, 4073, and 4534 kg/ha at application rates of 0, 25, and 50 cm/yr, respectively. N, P, and K did not differ statistically in either the soil or the plant concentrations. Results show that increased effluent applications increase dry matter yields, which lead to increased nutrient removal from the soil.
