GRIGG Suprema is a multi-nutrient formulation that contains 12% nitrogen, 12% potassium and amino acid complexed iron, manganese and zinc. It is an excellent option for zero phosphorus fertilizer programs.

Key Features

  • Contains soluble nutrients for efficient uptake and use
  • Provides an efficient source of nitrogen and potassium at a 1:1 ratio
  • Potassium regulates primary physiological processes that impact turf response to stress and supports cellular processes that impact photosynthesis, water regulation, respiration and protein production.

Rate Recommendations For Professional Use

To prevent or correct nutrient deficiencies, apply GRIGG SUPREMA as a foliar spray early in the morning or late afternoon. Allow 3-6 hours for drying time before irrigation. Best to apply after mowing.


Cool Season Grasses:
Apply 4-12 fl oz per 1,000 sq ft or 1.25-4 gal per acre [13-40 L per hectare] as needed every 14 days.
Warm Season Grasses:
Apply 6-15 fl oz per 1,000 sq ft or 2-5 gal per acre [20-50 L per hectare] as needed every 14 days.


Make frequent applications at lower rates, or apply higher rates at times of 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.

Mixing and Handling Instructions

  1. Agitate before use.
  2. Apply in 1-2 gal of water per 1,000 sq ft (44-88 gal of water per acre) [400-800 L of water per hectare].
  3. Fill mix tank with half of required water volume and begin agitation.
  4. Add products in this order, mixing thoroughly after each addition: adjuvants, pesticides, then fertilizers.
  5. Fill tank with remainder of water and continue agitation until solution is completely mixed.

Check chemical mixture compatibility using a jar test prior to application.
