Milorganite is an excellent sustainable fertilizer for turfgrass. It contains slow-release nitrogen for sustained feeding without any burn potential. Milorganite phosphorus is plant available but resistant to leaching, and the iron is non-staining.
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 LBS per 1000 SQ FT, 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 a low rate of nitrogen.
Iron is important for turfgrass color. However, most iron fertilizers will stain concrete surfaces such as walkways, cart paths, deck areas, and markers, and the rust stains can persist for a long time. Milorganite can be used safely around concrete to provide plant-available iron without staining. Expect to see improved turfgrass color, without rust-colored speckles on concrete.
Milorganite is often used to improve turf color and density where poor growth and color are observed. Expect to see more dense turf with better color. Extra fertilization with Milorganite can improve turf growing on isolated regions within a fairway that has unusually sandy soil, thin soils over rock, or in places with low organic matter. Apply 20 to 50 LBS Milorganite per 1000 SQ FT to these areas. Milorganite often is used around bunker perimeters to improve weak turf. Use Milorganite mixed with sand (eg. 50/50 by volume) as a topdressing on thin spots on greens. Apply weekly until the turf has recovered.
Milorganite mixed with topdressing sand at the rate of 10 or more LBS per cubic yard of sand will speed recovery from core aerifications or verticutting. The low-salt property of Milorganite makes it preferable to chemical fertilizers which may stress grass that already is damaged by the aerification, and Milorganite fortifies the sand topdressing with organic matter.

Seeding, Sodding and Sprigging: Apply Milorganite when you till the soil. Apply at twice the rate for mature turf. This ensures adequate nutrients are available for starting these seedlings. Till in the Milorganite to a depth of two inches (four inches tilling depth). After the third mowing, apply Milorganite at recommended rates for mature turf.
Overseeding: When overseeding, superintendents must balance the seedling nutrient needs versus the need for the permanent turf species to go into winter dormancy. Apply lower amounts of nitrogen than during the normal summer growing season, but make sure that annual grass seedlings are not nutrient deficient. A suggestion is to apply 1 LB N per 1,000 SQ FT at seeding and at least once during winter months to relieve nitrogen stress.
