Advanced Silicon

Macro-SI™ pairs high-quality soluble silicon with Macro-Sorb’s advanced amino acid technology to promote rapid nutrient uptake and utilization.  The proprietary formulation in Macro-SI™ delivers readily available silicon activated with a complex of specific amino acids.  These Macro-Sorb amino acids boost silicon absorption into plant tissue and jump starts natural defense mechanisms within the plant.

Product at a Glance: 
  • Superior soluble silicon enhanced with Macro-Sorb amino acids
  • Increases biotic and abiotic stress tolerance caused to plants
  • Improves turf quality
  • Enhances turf aesthetics and playability
  • Specific amino acids improve performance of silicon within the plant

Apply 1 – 2 oz. per 1000 sq. ft. every 14 – 28 days throughout the growing season.  Macro-SI™ can be taken up by plant roots and shoots; however, greater efficacy is achieved following soil applications.  For soil applications, it is recommended to irrigate after application with at least 0.125 inches of irrigation.  Apply Macro-Si™ with at least 1.5 gallon of water per 1000 sq. ft., or 60 gallons per acre spray volume.
