A workshop next month in western Ohio aims to clean up Grand Lake St. Marys — and in doing it, give farmers a new source of income. “Turning Manure into Ca$h” features new technologies for turning livestock waste into sellable fuel, fertilizers, and bioresins. It’s on March 8 in Maria Stein, about 10 miles south of the lake. OSU Extension is one of the sponsors. “We have new manure rules in place for Grand Lake, but we still have the same amount of manure, so we need to look at ways of reducing our nutrient loads,” said Jim Hoorman, one of the speakers and an OSU Extension educator in Mercer County. “Farmers can adopt these technologies, sell their manure for a profit, and reduce their nutrients.”
