Fertoz Rock Phosphate 0-20-0

Organic Phosphorus for Root Growth, Flowering & Long-Term Soil Fertility

Fertoz Rock Phosphate 0-20-0 is a natural, finely ground mineral fertilizer made from sedimentary phosphate rock. With 20% available phosphate and high calcium content, it provides a slow-release source of phosphorus that builds over time-feeding root systems, flowering plants, and microbial life without leaching or burning.

Ideal for use in vegetable gardens, orchards, pastures, compost piles, and regenerative field systems, Fertoz is OMRI-listed and safe for long-term soil building.

Key Characteristics

  • High-Phosphorus Fertility for Roots and Blooms
    Rock phosphate supports vigorous root formation, seedling establishment, and flower and fruit production. It is especially important in no-till systems, phosphorus-deficient soils, and perennial crop systems.

  • How to Use in Gardens, Orchards, and Compost

    • Garden beds: Apply 5-10 lbs per 100 sq ft and incorporate into the top 3-6".

    • Fruit trees: Apply 1-2 lbs per tree annually around the dripline.

    • Compost pile: Add 2-4 cups per cubic yard to boost phosphorus and calcium for fungal-dominant compost.

    • Soil mixes: Use ½-1 cup per cubic foot when blending for transplants or potting mixes.

  • Improves Microbial Activity and Long-Term Soil Health
    Phosphorus must be mineralized by soil microbes to become plant-available. Fertoz's fine grind and natural mineral form make it ideal for pairing with mycorrhizal fungi, compost teas, and microbial inoculants, encouraging nutrient cycling and fungal soil webs.

  • Best For These Crops and Systems

    • Root crops (carrots, beets, radish), legumes, onions, and garlic

    • Tomatoes, peppers, squash, melons, and cucurbits

    • Fruit trees, berries, and vines

    • Pastures, hay fields, cover crops, and no-till gardens

    • Compost enrichment and fungal-leaning soils

  • OMRI-Listed and Non-Leaching
    Fertoz is a safe, slow-release input that remains in the root zone and doesn't leach into groundwater. Ideal for regenerative fertility plans focused on phosphorus efficiency and closed-loop soil health.
