The document discusses sediment and nutrient losses measured at the Soaring Eagle Dairy farm from 2004-2006, finding that a three day runoff event in 2006 accounted for 92% of sediment losses that year, while nitrogen losses occurred predominantly during non-frozen periods but phosphorus losses were more substantial during frozen periods than sediment losses. Proper management of grassed waterways and an understanding of tile drainage impacts are important to reduce sediment and nutrient runoff from agricultural fields in Wisconsin.
