By Mary Wicks In 2021, an OSU Extension educator, John Smith, recruited folks from OSU, SWCDs and other agencies to launch the first Manure Science Review (MSR). The goal was to provide an educational program that provided research-based information on manure handling and other issues facing livestock producers. It was a success and has continued into 2021, always following Smith’s mantra that you need to provide high quality information, impressive equipment demonstrations, and good food. Since its beginning, over 4,000 people have attended the MSR, learning from the experts in the manure world on everything from regulations to application methods to environmental issues. The MSR has been held in 16 different Ohio counties in its 20 years of existence. The always popular field demonstrations have included the unique Subsurfer for injecting poultry litter, smoking subsurface drainage tiles, many solid and liquid manure applicators, cover crop plots, and holey underwear. And of course, the food has always been plentiful and delicious.
