Nature Safe 21-3-7 with UFLEXX

Nature Safe 21-3-7 combines the value, nutrition and efficiency of Nature Safe Natural & Organic Fertilizers with the fertilizer efficiency of stabilized nitrogen found in UFLEXXTM.  The result is a turf and landscape fertilizer with an emphasis on efficiency and cost-effectiveness. This is a blended product with 60% Nature Safe (with Sulfate of Potash) and 40% UFLEXX. The Nature Safe component is constructed of various pet food grade proteins such as meat, bone and blood meals that provide slow release nitrogen to the plant for 7-8 weeks. UFLEXX is a combination of urea, a urease inhibitor (NBPT) and a nitrification inhibitor (dicyandiamide), which provides nitrogen over 6-8 weeks while reducing nitrogen loss due to leaching, volatilization and denitrification. With an SGN of 230, Nature Safe 21-3-7 is a low-cost alternative for fairway, landscape and lawncare applications.
