Zinc Fertilizer Specs.pdf

F-425 G has a guaranteed analysis of 25.00% Zinc (Zn) by weight, with 8.00% soluble zinc. Its bulk density is 90-95 lbs. per cubic foot, and its particle size is 90% -6 + 16 Mesh (-4 + 1 mm) with a 180 SGN. The product appears as grayish brown granules. Packaging options include bulk, bulk bags, or 50-pound multiwall paper bags with a PE liner, shipped from Walnut Ridge, AR.

Agronomic considerations highlight its low zinc analysis for excellent field distribution and high solubility for immediate nutrient availability. The remaining zinc is in finely divided oxide and carbonate forms to build soil reserves.

General recommendations suggest applying the product based on soil test and/or leaf analysis results, with typical use rates of 10-25 pounds per acre for broadcasting or 5-15 pounds per acre for side-banding at planting. Manufacturing considerations involve normal bulk blending procedures, intended for mixing or blending with other materials to produce products with total primary nutrient guarantees of 24% or higher. The product is available from Frit Industries, located at 1792 Jodie Parker Road, Ozark, AL 36360, phone 334-774-2515.
