Built for Hydro-Seeders. Addresses the two most critical factors affecting new turf establishment: adequate phosphorous utilization and adequate soil moisture. Hydra-Blast ensures that adequate moisture is present in soil. Our proprietary Nutrient Efficiency Polymer (Nutri-Charge) is a negatively charged polymer that sequesters cations, such as calcium. The moisture retention polymer also modifies the viscosity of the tank mix, making it slightly thicker which facilitates on-target deposition of hydro-seeded areas and ensures seed/fertilizer mixture stays in place.
