Milorganite has been fertilizing home lawns and golf courses since 1926. One of its many benefits is it's consistency: Milorganite has not changed over time. It is produced from the same source of microbes every year, so you get the same great product year after year.
Over 85% of the nitrogen in Miloranite is a slow release form. This means that the nitrogen is released to your lawn and plants as they require this essential nutrient. Fast release nitrogen forces plants to grow too fast, which can cause stress, especially during the hot summer months. And stress can encourage disease and insect damage. Milorganite's slow release formula simply waits for moisture to be present to begin breaking down the nitrogen, which means you can apply it during the hottest, driest weather without fear of damaging your lawn.
Milorganite also contains 4% naturally complexed iron. This type of iron turns your lawn a dark, lush-lookinig green without causing excessive growth - but won't stain concrete patios or walks.
