Rate:
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.

Macro-SI
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 start natural defense mechanisms within the plant.

-
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
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
Untreated
(washed)
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.
