Talk about sustainability. Turn yard wastes into fish food, and plant fertilizer for raising fish and vegetables. Learn simple instructions to create a DIY bioponic garden using 55-gallon barrels, rainwater, and common plumbing parts. Find out how nutrient cycling from yard waste is used to grow duckweed as a fish and livestock feed, tilapia and crawfish, plus liquid fertilizer for nourishing plants both in-ground and in soil-less hydroponic/aquaponic garden systems. Presented by David Epstein, and Kenneth Lovell at the 2012 Georgia Organics Conference in Columbus, GA.
