Time for milking
The current manure management system at the Jordan Farm, which has about 300 cows at this location, is to collect the manure under the barn. Manure drops through the slots in the floor where it collects in a container and then is pumped into a lagoon. When warmer weather came, the manure was sprayed on fields for fertilizer. With the digester, the farm will be able to make energy from the manure and shipped-in food waste and recycle the nutrients. At the end of the digestion process, the remaining liquid will be used as fertilizer.
