Milorganite by Promate, 50lb
Milorganite is one of the oldest branded fertilizers on the market. It’s composed of heat-dried microbes that have digested the organic matter in wastewater. Milorganite is manufactured by capturing wastewater from the metropolitan Milwaukee area, including local industries such as MolsonCoors.
Using large-scale processes that mimic nature, microbes digest the nutrients found in the water. The cleaned water is returned to Lake Michigan while the microbes are kiln-dried into small pellets. So Milorganite is actually a bag of dried microbes!
