Cal Poly Compost Production
Cal Poly began on-campus composting operations during the 1990s. Initially, the operations relied on static piles to compost manure. In 1997, Dr. Doug Willimas initiated windrow composting operations, which developed into an enterprise project with the BioResource and Agricultural Engineering Department. As the composting operations expanded and required increased management, they were assigned to the Agricultural Operations Department. Today, under the guidance of department staff and supervision of student employees, the compost unit processes over 7,000 cubic yards of manure and 3,500 cubic yards of green waste and wood chips into 3,500 cubic yards of finished compost
The composting operations process livestock manure from the dairy, beef evaluation center, beef unit, equine center, and poultry unit and incorporate the green waste generated from campus landscaping. In 2011 the Cal Poly composting operations became members of the U.S. Composting Council's Seal of Testing Assurance Program.
Manure Management
As part of Cal Poly's Water Quality Management Plan, Agricultural Operations is responsible for maintaining the confined livestock operations on the campus farm. This involves manure management of both solids and liquids. Solids are removed routinely and composted or spread on approved fields and pastures identified in the water quality management plan. Liquids are captured within lagoons at several of the animal units. The accumulated lagoon water is then utilized as an irrigation resource on fields and pastures approved within the water quality management plan. Associated with the use of both lagoon water and lagoon solids are specific quarterly water quality monitoring requirements designed to ensure proper use and monitoring of ground water resources.
