Front Row Ag PhosZyme is a concentrated, dry-soluble enzyme biostimulant combining mannanase, phosphatase, and monoammonium phosphate (MAP). It is designed to improve phosphorus bioavailability, enhance water uptake, and promote root development across all growth stages. Mannanase supports water transport and releases sugars into the root zone, while phosphatase helps convert phosphorus bound to substrate cations into plant-available forms. The MAP component provides an additional source of nitrogen and phosphorus. Its fully soluble formulation is suitable for hydroponic, coco, and soilless growing systems.
• Product Type: Dry-soluble enzyme biostimulant
• Brand: Front Row Ag
• Formulation: Fine, dry, water-soluble powder
• Active Enzymes: Mannanase and phosphatase
• Additional Ingredient: Monoammonium phosphate (MAP)
• Primary Role: Improves phosphorus availability, water uptake, and root development
• Phosphorus Availability: Phosphatase helps release phosphorus bound to cations in the substrate
• Water Transport: Mannanase supports water movement into the plant's xylem
• Root-Zone Benefits: Released sugars support root growth and microbial activity
• Application Rate: 0.4 g/gal of feed solution
• Coverage: Approximately 28,375 gallons per 25 lb bag
• Growth Stage: Suitable across all growth stages
• Growing Media: Hydroponics, coco, and soilless media
• Stock Tank Compatibility: Add to the Part B stock tank; in a two-doser system, add to the combined Part B + Bloom tank
• Mixing Limitation: Not calcium-compatible. Never mix with Part A or other calcium-containing concentrates
• Injection Compatibility: Stock-concentrate fertigation systems using dosers or injectors
• Irrigation Compatibility: Drip irrigation, NFT, and flood-and-drain systems when correctly dissolved in a calcium-free stock tank
• Recommended Integration: Front Row Ag recommends adding PhosZyme to the Part B stock at 10% of the carrier's weight
• EC Management: Contributes to total feed EC; adjust other nutrient doses using the applicable feed calculator
• Available Sizes: 5 lb and 25 lb
Key Advantage: PhosZyme combines two enzyme mechanisms in one soluble formulation: phosphatase helps unlock phosphorus already present in the substrate, while mannanase supports water transport and root-zone activity. For Front Row Ag users, incorporating it into the Part B stock tank simplifies fertigation by avoiding a dedicated dosing tank or injector. The critical requirement is to keep it separate from calcium-containing concentrates, especially Part A.
