Michael Conroy/AP As Hurricane Florence approaches the Carolinas, farmers need to work quickly to get as much out of their crops as they can and move animals to higher ground. Animal agriculture produces about 10 billion pounds of wet waste a year in North Carolina, and a lot of that waste is stored in open lagoons, which could flood. Some of this waste can be moved to fields, but farmers can legally only apply a limited amount of manure, and must stop hours before severe weather begins.
