Manure Management Regulations for Organic Dairy and Livestock in the United States

eOrganic author:

Jim Riddle, University of Minnesota

Organic livestock operations must manage manure in a manner that does not contribute to contamination of crops, soil, or water by plant nutrients, heavy metals, or pathogenic organisms, and which optimizes the recycling of nutrients. If manure is brought onto the farm from a non-organic source, it cannot have had non-approved synthetic additives added to the manure pits or piles. The non-organic animals could have been fed or bedded with non-organic crops, however.
