Due to water scarcity and increasing food demand, nonconventional water sources (e.g., human and animal wastewater) represent a valuable alternative to traditional water resources for agricultural use. Among these alternatives, treated animal wastewater, particularly feedlot runoff may represent a valuable solution in states like Nebraska due to its abundance. Subsurface drip irrigation (SDI) is a low-pressure micro-irrigation system that delivers water to the crop root zone through buried drip tapes with embedded emitters at fixed intervals. Despite multiple advantages (great water application uniformity, high water use efficiency, and improve fertilizer application), SDI can lead to poor aeration in the rhizosphere …
