Stinky Poo = Happy Me and You!

Project #2104

Many consider organic products to be healthier than those produced by chemical fertilizers. Using a homemade bioreactor system, I produced and compared clean, organic liquid fertilizer from dog and cow droppings. The system has two units: an ammonification unit and a nitrification unit. In the ammonification unit, dog or cow droppings are degraded under anaerobic conditions, producing ammonia in gas form. The ammonia is carried by jet air and introduced to the nitrification unit, where nitrifying bacteria convert the ammonia into nitrate, the primary nutrient required for plant growth. The fertilizer produced from dog droppings has higher amounts of nitrate. The fertilizers were tested successfully by growing plants.
