Blu-Gro® 10-4-6 Sulfur and Micronutrients is a 5:2:3 ratio liquid fertilizer with micronutrients that contains a high percent of ammonium and nitrate quick release nitrogen. Unlike slow release and urea nitrogen, ammonium and nitrate forms of nitrogen are immediately available to the plant which makes them especially ideal for use during cold temperatures. Blu-Gro® 10-4-6 is an excellent fertilizer to apply early in the spring, fall and any time quick release nitrogen is needed throughout the growing season. The micronutrients are in the EDTA chelated form which enhances their availability while in the soil and allows tank mix compatibility with many other products.
