  • 6% Fast-acting Ammonical Nitrogen:

    • The first CERTIFIED liquid organic fertilizer with 6% plant-available nitrogen … guaranteed!
    • The fastest-acting organic fertilizer in the industry today.
    • Equals the response time and efficacy of synthetic chemical urea.
    • The first liquid fertilizer organic fertilizer that performs during low ambient and soil temperatures of the early season

Additional Features:

  1. 6%N N²PK SuperSix 6-0-5 Liquid Organic Fertilizer contains no sodium nitrate (salt).

    Products that add sodium nitrate due so to raise their N percentages. It is a low cost fix to increase nitrogen, however it can only be used as a 20% supply of the overall fertilization. In order to comply with OMRI and NOP regulations the grower can only use products containing sodium nitrate as 20% of their overall nitrogen application. N²PK SuperSix 6-0-5 liquid organic fertilizer can be applied as the total source of N.

  2. The nitrogen in N²PK SuperSix 6-0-5 is ammoniacal.

    The 6% fast-acting ammoniacal nitrogen in N²PK SuperSix 6-0-5 makes it the fastest-acting organic fertilizer in the industry today. N²PK SuperSix 6-0-5 equals the response time and efficacy of synthetic chemical urea. Ammoniacal nitrogen is quick-release and readily available for use even in the low ambient and soil temperatures of the early season. This allows it to be used anywhere in the U.S, and in some cases, it may be the difference that will allow the grower to plant an additional crop per season.

  3. Easily deliverable. Fertigation-ready

    N²PK SuperSix 6-0-5 is filtered through a 500-mesh screen and can be applied by any irrigation or fertigation system.

  4. High 5% potash content.

    Most of the products that do not add potash are 1% potash or less. Potash is expensive. We deliver high N and high K in our product at a very competitive price. Potash is currently at $350.00 per ton and has spiked as high as $600.00 per ton when demand is high.

  5. Zero Phosphorous.

    Having zero phosphorous makes N²PK SuperSix 6-0-5 a great product for the pro-turf / golf industry. The EPA has put demands on the golf industry to limit the amount of phosphorous applied to the courses. They are also mandated to reduce the use of synthetic fertilizers by 20 %. The EPA has banned the use of fertilizers containing Phosphorous on residential property in certain States and soon the ban will be expanded to include all states. Phosphorous leaching is the leading reason for ground water contamination.

  6. Product Availability.

    Most liquid organic fertilizer manufacturers are small operations unable to supply large quantities of product on a timely basis. BioStar will produce 2,000,000 gallons of N²PK SuperSix 6-0-5 per year at each facility. That's 38,461 gallons / week.
