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.
6X1 liter (1.58 US gallons) case

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 start natural defense mechanisms within the plant.

Enhances turf aesthetics and playability
Specific amino acids improve performance of silicon within the plant
Increases in Leaf Silicon Content
Macro-SI was applied to creeping bentgrass as a spray application at the given rate and then watered-in with 0.25 inch of irrigation. Tissue samples were collected and analyzed five days after application for silicon content. Macro-SI increased tissue silicon content by 29 and 44 percent following 1.0 and 4.0 fl oz. per 1000 ft2, respectively.
Silicon Deposits in Leaf Tissue After Macro-SI Application
X-ray microanalysis of leaf surfaces treated with Macro-SI. Red color indicates the highest Si deposition and black represents absence of its deposition. Leaves were washed to remove any surface Si. Plants treated with Macro-SI had significantly more silicone incorporated into their plant tissues. Notice how silica is deposited in the intercellular space (right image), creating a physical barrier to protect against pathogen attacks and add structural strength leading to improved wear tolerance for turfgrass.
