Milorganite Non-Burning Fertilizer for Lawns & Plants

Milorganite Non-Burning Fertilizer for Lawns & Plants


What is Milorganite?


Milorganite is an all-purpose organic nitrogen fertilizer that can be used on lawns, shrubs, trees, flowers, vegetables, and as a seed carrier. Milorganite contains 85% organic matter, which promotes beneficial microbial activity and improves the soil’s ability to grow and nurture grass and plants. Milorganite is ideal for sandy soils because it does not leach.


Milorganite fertilizer is one of the oldest branded fertilizers on the market today.  It is composed of heat-dried microbes that have digested the organic matter in wastewater.  Milorganite is manufactured by the Milwaukee Metropolitan Sewerage District.  The District captures wastewater from the metropolitan Milwaukee area, including local industries such as MillerCoors.  This water is then treated with microbes to digest nutrients that are found in it, and cleaned water is returned to Lake Michigan.  The resulting microbes are then dried, becoming Milorganite fertilizers.  The Milorganite program is one of the world’s largest recycling efforts.
