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.
