DPC 27, Dairy Manure Management from Barn to Storage

Item #: DPC-027

Published: 1998

Pages: 36

This Guideine provides information on manure management from barn to storage, with insight on planning and impementation. It is important to plan ahead for small and large improvements in dairy manure systems to predict the costs, risks, savings, and operating changes that will occur. There are many options, thus careful and objective planning is a key to success.
