Neptune's Harvest Turf Formula was specifically designed for use on lawns in the many communities that now have zero Phosphorus laws. According to the company, it will provide the necessary nutrients for tolerating environmental conditions such as high temperature and drought, while offering plenty of macro- and micro-nutrients for improved vigor and color. It will increase nutrient efficiency, while increasing root mass and microbial activity, and will increase turf health and reduce disease. It’s a high-energy mix that will show results in days. Ingredients: Hydrolyzed Fish, Molasses, Seaweed (Ascophyllum Nodosum), Humate, and Yucca Extract.
