Fertoz

Fertoz is a granular, rock-phosphate-derived phosphorus fertilizer built for long-term phosphorus availability and soil balance. It delivers slow-release phosphorus to establish strong roots and steady growth, while contributing calcium and silica that support soil structure and plant resilience.

How to use

Some phosphorus-deficient soils may need large initial applications of up to 1,000 lbs per acre (about 23 lbs per 1,000 square feet) to reach balance. After the soil is balanced, only maintenance amounts of roughly 100 to 200 lbs per acre (about 2 to 5 lbs per 1,000 square feet) are usually needed, adjusted to soil tests and crop needs. The rock-phosphate origin releases gradually as soil biology becomes active.

For soil test-specific recommendations or local guidelines, consult your extension service or a soil laboratory.
