The Only True Potassium PolyPhosphite
PolyPhosphite 30® (0-0-27) is a pure Potassium PolyPhosphite fertilizer solution that is manufactured in a one step process by reacting Phosphorous Acid and Potassium Hydroxide in a patented high temperature, rapid cooling process that preserves the maximum amount of Phosphorous in the desirable H3PO3 (Phosphorous Acid) form. This unique PolyPhosphite 30® (0-0-27) manufacturing process neither contains nor requires any H3PO3 preserving or solubility additives that are necessary in competitive products. As a result, PolyPhosphite 30® (0-0-27) economically feeds and protects the plant through superior Phosphorous Acid nutrition. PolyPhosphite 30® (0-0-27) is rapidly absorbed by turfgrass blades for maximum nutritional benefit in order to prevent and correct nutrient deficiencies and to promote disease resistance. Note: With foliar applications, phosphite ions are taken up directly by the plant foliage and may undergo a degree of conversion to phosphate ions, or be utilized directly by the plant as phosphite ions.
Directions For Use:
Greens, Tees and Fine Turf: Apply 2.0 - 6.0 oz. of PolyPhosphite 30®(0-0-27) with 1.5 - 2 gallons of water per 1,000 sq. ft. (0.7 - 2.0 gallons of PolyPhosphite 30® (0-0-27) with 66 - 88 gallons of water per Acre) every 10 to 21 days throughout the growing season. This application shall provide 0.05 - 0.18 lb. of actual Potassium per 1,000 sq. ft.
Fairways, Roughs, Sports Turf and Lawn Care: Apply 1.0 - 1.5 gallons per Acre of PolyPhosphite 30® (0-0-27) with 44 - 88 gallons of water per acre (3.0 - 4.4 oz. of PolyPhosphite 30® (0-0-27) with 1 - 2 gallons of water per 1,000 sq. ft.) every 14 days throughout the growing season. This application shall provide 0.08 - 0.11 lb. of actual Potassium per 1,000 sq. ft.
Fertigation: PolyPhosphite 30® (0-0-27) may be injected through fertigation systems. The systemic action of PolyPhosphite 30® (0-0-27) allows foliar and root uptake within the turf plant. Inject the equivalent of 1 - 1.2 gallons of PolyPhosphite 30® (0-0-27) per acre. Use the lower rate for weekly injections. Use a higher injection rate when applying every 10 to 14 days or during higher stress conditions.
Tree & Shrubs: Broadcast Soil Method: Mix PolyPhosphite 30® (0-0-27) at 2 quarts per 100 gallons of water and apply as a soil drench or soil injection at the rate of 25 gallons per 1000 sq. ft. of root zone.
Basal Drench/ Injection: Mix PolyPhosphite 30® (0-0-27) at the rate of 2 gallons per 100 gallons of water. Drench the soil near the stem of the shrub or tree at the rate of 1 quart per inch of stem diameter at 4.5 feet (DBH) or 1 quart per foot of height for shrubs. A soil wetting agent can be added to the mixture to improve soil penetration.
Foliar Spray: Mix PolyPhosphite 30® at the rate of 2 quarts per 100 gallons and apply a spray to wet the foliage. The addition of a sticker spreader at labeled rates is recommended.
