The impact of manure addition on corn yield and sediment losses in snowmelt and rainfall runoff under moldboard plow (MP) and ridge tillage (RT) systems was studied. In 1993, the grain yield was not affected by manure addition irrespective of tillage because of high rainfall. Snowmelt runoff was not affected by manure application and it transported <0.1 Mg sediment ha-1. The manure reduced rainfall runoff by 10 mm in 1993 and 3.2 mm in 1994, leading to the reduction in sediment losses of 2.5 and 0.2 Mg ha-1, respectively.
