The intent of this study is to quantify the leaching of wastewater nitrogen and phosphorus following land application during the non-growing period. The wastewater is generated from a potato processing facility in Park Rapids, Minnesota. The presentation will cover the design of an undisturbed leaching lysimeter and some preliminary data on leaching of nutrients following the wastewater application onto frozen soils.
