Fertoz is a rock-phosphate–derived phosphorus fertilizer from The Soil Makers, designed for long-term phosphorus availability and soil balance. This granular product delivers meaningful phosphorus to establish strong roots and steady growth, with a composition that also contributes calcium and silica to support soil structure and plant resilience. The visible granules reflect a natural rock-phosphate blend, ideal for garden beds, lawns, and established turf.

• Derived from rock phosphate
• Packaging suggests accessibility in 50 lb quantities with shipping promotions

What this means for your soil and plants:

• Slow-release phosphorus supports root development, flowering, and fruit set over multiple growing cycles, helping plants efficiently access essential nutrients as the soil warms and microbes become active.
• Calcium-rich formulation helps improve soil pH balance and soil structure, promoting strong root zones and better nutrient uptake.
• Silica content contributes to plant strength and stress tolerance, supporting sturdier stems in windy or drought-prone conditions.
• Rock-phosphate origin provides a natural, mineral-based source of phosphorus that releases gradually as soil biology works, reducing the risk of nutrient surges.

Usage guidelines (soil-building and maintenance context):

• Large initial applications may be appropriate where soils are deficient in phosphorus. Typical starting rates can reach up to 1,000 lbs/acre to kick-start phosphorus availability and balance, with subsequent maintenance applications in the range of 100–200 lbs/acre as soil tests indicate balanced nutrient release.
• For planning purposes, applying roughly 23 lbs per 1,000 sq ft corresponds to 1,000 lbs per acre, while maintenance applications are about 2–5 lbs per 1,000 sq ft depending on soil conditions and crop needs.
• Ideal for lawns, vegetable plots, ornamental gardens, and established turf where phosphorus is a priority for root growth and overall vigor.

Who benefits most from Fertoz:

• Home gardeners upgrading soil phosphate reserves to support long-term plant health.
• Small-scale growers and landscapes where a steady, slow-release phosphorus source aligns with seasonal feeding needs.
• Soils that require an upfront phosphorus boost to reach a balanced baseline before maintenance nutrient cycles take effect.

Why choose The Soil Makers' Fertoz—unique value you can feel over seasons:

• Rock-phosphate–based formula designed for sustained nutrient release, reducing the risk of phosphorus run-off and heavy demand spikes.
• Concrete phosphorus numbers you can reference for soil balancing, paired with calcium and silica contributions that support soil health and plant resilience.
• Brand heritage built on practical, garden-tested nutrition strategies that focus on soil biology and long-term fertility.

Total Phosphorus is 20%, available phosphorus 7%, CaO is 31%, SiO2 is 26%. The product is derived from rock phosphate. Phosphate (P2O5) is one of the major macronutrients along with Nitrogen (N), and Potash (K2O). Some soils may need large initial applications (up to 1000 lbs/acre) to bring the soil to a point where it will release sufficient phosphate to the plant. After the soil is brought to balance, only maintenance amounts (100-200 lbs/acre) are usually needed.
