GRIGG Endurance Overview
GRIGG Endurance contains three sources of nitrogen, phosphorus, potassium, secondary and micronutrients, sea plant extract and humic acid. It is recommended for in-season use to revitalize turf vigor and color. It is also ideal for fall application to prepare turf for winter.
Key Advantages
- Contains soluble nutrients for efficient uptake and use
- Nitrogen promotes consistent turfgrass shoot growth
- 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.
- Calcium is important for cell wall strength
Application and Use
General Maintenance of Cool and Warm Season Grasses: Apply 6-10 lb per 1,000 sq ft or 261-435 lb per acre [3-5 kg per 100 sq m or 292-488 kg per hectare] as needed.
Promote Plant Recovery: Use this product to increase turfgrass vigor and recovery from mechanical and/or environmental stress. Apply 8-10 lb per 1,000 sq ft or 348-435 lb per acre [4-5 kg per 100 sq m or 390-488 kg per hectare] 1-3 days after aeration, spiking, verticutting or other mechanical disruption to promote recuperation and speed time to recovery.
Establishment: As a pre-plant fertilizer, incorporate 10 lb per 1,000 sq ft or 435 lb per acre [5 kg per 100 sq m or 490 kg per hectare] to root-zone mix or soil during seedbed preparation.
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.
