Mixing grass seed with Milorganite makes it easier to accurately spread seed. The standard Milorganite-to-seed is 4 to 1 by weight. When mixing seed and Milorganite, make sure you decrease the rate of other Milorganite applied to avoid over-fertilization.
Seeding
Spread seed or Milorganite – seed mix evenly on the prepared soil. Gently work the seed into the soil 1/16 to 1/8 inch. On light (sandy) soils, watering alone may be adequate for seed incorporation. Cover with a thin layer of weed seed free mulch to help conserve moisture.
Watering
Keep the seeded area moist until seed emerges. Frequent, light watering is necessary at this time. After seedlings are ½ to 1 inch tall and climatic conditions allow, reduce watering to several times per week at depth of one to two inches. Keep the root zone moist. Decrease frequency and increase depth of watering as seedlings mature.
Mowing
Mow the new turf as you would mature turf. Keep your mower blades sharp. Mow only when turf is dry. Remove a maximum of 1/3 leaf at any one time. Because new turf contains a high amount of water, collect clippings to prevent smothering new turf.
Dormant Feeding
Superintendents use every tool available to them to have courses ready for play as soon as snow cover leaves. Applying Milorganite in very late fall or just prior to a winter snow cover is part of this program.
The University of Wisconsin conducted a two-year study to evaluate dormant feeding on bentgrass greens. Color response was measured. It was found that microbial activity occurred during winter months. This released a small amount of nitrogen. This nitrogen was then available to the bentgrass as soon as snow melted.
Bentgrass color was recorded every seven to ten days after snowmelt. Measurements continued until mid-May. Dormant applications of Milorganite significantly improved bentgrass color, ranging from 0.4 to 1.4 units. This increase in quality was noted on both well- and poorly-drained greens.
Additional benefits of a dormant Milorganite application include:
- earlier recovery from winter injury
- aids in recovery from snow mold damage
- turf damage repair from early season play

Athletic fields
Milorganite has long been an integral part of sports field maintenance, including the preparation for many Super Bowls. Milorganite promotes dense turf, which increases footing and fall protection. Milorganite's high amount of slow release nitrogen encourages deep rooting for durability and stress resistance.

Spoon Feeding
Using Milorganite Greens Grade 6-2-0 helps level peaks and valleys because its nitrogen releases slowly over time, without excessive amounts being available quickly after application. Because you are applying small amounts of nitrogen, using a low analysis fertilizer helps eliminate streaking.
Milorganite contains 6% nitrogen.
This means that to apply 0.33 lbs. nitrogen per 1000 square feet in a spoon feeding program, you need to apply 5 ½ lbs. Milorganite per 1000 square feet.
This is easier to spread evenly than the 1 1/3 lbs. of a 27% nitrogen granular fertilizer needed over that same area.
Spoon feeding with Milorganite offers other advantages:
- Frequent light applications provide a constant energy source for soil microbial activity
- Provides a constant source of organically-complexed iron for deep green color throughout the season
- Benefits of faster, easier and affordable applications
- one spoon feeding application can be accomplished by one employee in about the same time it takes to change cups
- 100,000 square feet of greens will require less than ten bags at an application rate of 0.35 pounds of nitrogen per 1,000 sq. ft.
Lawn Care
Milorganite is the ideal choice for lawn fertilizer programs that use organic nitrogen as their base. Milorganite® 6-2-0 will not burn turf. It will not cause “leggy” ornamental plants if it accidentally is applied to them. Produced and sold since 1926, Milorganite delivers the results customers demand.
