Milorganite All Purpose

Free Shipping on All Orders

It is the leading organic nitrogen fertilizer used. Across North America and around the world, anywhere you need to fertilize, Milorganite is the proven, reliable and safe organic nitrogen fertilizer. Sized at SGN 160, this fairway sized granule quickly drops through the turf canopy to rest on the soil surface until rain or irrigation activates its’ nutrients.

For Use In

Use Milorganite as a general fertilizer to promote healthy turfgrass growth without the peaks and valleys of growth and color associated with readily soluble nitrogen. Milorganite Greens Grade is well suited for closely-mowed golf greens and Milorganite Classic is suitable for fairways and lawns. Both have excellent physical properties making application easy. Expect long-lasting growth and color with very little nitrogen leaching. Make monthly applications at the rate of 20 pounds per 1000 square feet or higher rates less frequently. Milorganite is excellent in spoon feeding programs because it has a moderately low analysis so it can be applied easily at low rate of nitrogen.


Milorganite is an organic nitrogen fertilizer guaranteed to contain not less than 6% nitrogen, at least 85% of which is water insoluble (WIN). The available phosphorus is not less than 2%. Milorganite also contains at 4% iron. Calcium in Milorganite helps in neutralizing acidic soils and the effects of its’ nitrogen.
