It provides three sources of nitrogen, phosphorus, potassium, secondary and micronutrients, sea plant extract and humic acid. It corrects nutrient deficiencies and maintains turf color.

Key Advantages Contains soluble nutrients for efficient uptake and use at a 1:1:1 ratio of NPK Contains ferrous sulfate which supplies quickly available iron. Iron plays a key role in chlorophyll production, which improves turf color. Nitrogen promotes consistent turfgrass shoot growth Phosphorus plays a role in plant metabolic processes that transfer energy throughout the plant Soluble potassium is derived from sulfate of potash. Potassium regulates primary physiological processes that impact turf response to stress and supports cellular processes that impact photosynthesis, water regulation, respiration and protein production.
