In the southern United States, fertilization of golf course putting greens during the winter months is an important period in a turf manager’s fertility program.
Throughout this period days are shorter resulting in less net photosynthesis. Low soil temperatures significantly reduce microbial activity and nutrient cycling. The result is a turfgrass plant that struggles to obtain essential nutrients at the time it needs it most.
Nature Safe is an important component of a winter feeding program. Many turf managers use 0.25 to 0.5 lb. N/1,000 sq. ft. of 8-3-5 SF per application to provide an organic source of soluble nutrients for both the plant and microbial community.
University research shows that turf managers can benefit from the use of organic sources of fertilizer during winter (Lazarovits, Agriculture & Agri-Food, Canada, 1999). Dr. Lazarovits observed that Nature Safe continued to feed microbes at soil temperatures below 50 degrees. Nature Safe is active at low temperatures because of the animal meal components used to make Nature Safe fertilizer. The amino acids are bound together in a manner that allows the nutrients to release at temperatures where other organics don’t.
Nature Safe N is released more consistently over time than N from other organic fertilizer sources. Manure and sludge-based organics have an uneven release curve and can unexpectedly release large amounts of N during warm spells. This can cause a strong flush of lush growth that is invariably killed when the next cold spell hits.
Nature Safe will not cause undesirable flushes of growth, decomposes thatch, builds root mass, promotes turf density and enhances disease management.
