Film: Organic Fertilizer (Costa Rica)
Now Viewing: Organic Fertilizer
At EARTH University's model farm, effective microorganism technology, also called 'EM,' is used to deal with livestock waste and increase soil quality. Natural bacteria and yeasts decompose cow manure into rich organic fertilizer, making chemical fertilizers unnecessary. The microorganisms also help keep away those pesky flies!
