GRIGG 10-2-4 is a greens grade fertilizer that contains two sources of nitrogen, phosphate, potassium, secondary nutrients, humic acid and sea plant extract.
General Maintenance of Cool and Warm Season Grasses: Apply 7-10 lb per 1,000 sq ft or 305-435 lb per acre [3.5-5 kg per 100 sq m or 342-488 kg per hectare] as needed.
Make frequent applications at lower rates, or apply higher rates for greater plant demand. Optimum rate of application will vary depending on treatment interval, soil properties (such as pH, organic matter content, texture), weather conditions, time of year, plant species and its nutrient requirements. For best results, follow soil/tissue test recommendation.
