Proven for Over 85 years

For over 85 years Milorganite has fertilized golf courses, home lawns and gardens.

All Purpose

Milorganite is an all-purpose organic nitrogen fertilizer that can be used on lawns, shrubs, trees, flowers, vegetables, and as a seed carrier. 

Goof-Proof -Will Not Burn 

Milorganite is worry-free because it contains virtually no salts, so it will not burn plants – even in the hottest temperatures and driest conditions. You don’t have to water it in, it will stay in the soil ready to work when moisture comes later.

Slow-Release for Balanced Growth

Milorganite’s slow-release formula provides nitrogen and other nutrients up to 3 months, for even growth (without excessive grass clippings) and better root development. Because grass is able to use these nutrients over a longer period of time, less fertilizer is wasted by seeping into groundwater or running off into streams.

Adds Organic Matter to Feed the Soil

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.

Iron that Greens without Staining

Milorganite’s iron is exceptional at delivering a long-lasting green. Unlike iron salts in some synthetic fertilizers, Milorganite’s organically complex iron won’t stain concrete.

Environmentally Friendly and Sustainable

Milorganite is one of the nation’s oldest recyclers, transforming a byproduct into a highly effective fertilizer.  No mined resources are used in production; Milorganite continues to explore alternative energy sources such as solar, digester methane, and landfill gas to run its operations. Milorganite is certified by the USDA as a bio-based product since it is derived from renewable materials.

Essential Nutrients

It takes more than nitrogen, phosphorus and potassium to optimize plant vigor. Fortunately, Milorganite contains all 13 essential plant nutrients, including secondary nutrients like calcium and micronutrients like iron and zinc.
