If your soil test shows low phosphorus levels, Triple Super Phosphate 0-46-0 provides a concentrated phosphorus source to restore balance and support proper root development.
This product is designed specifically for correcting phosphorus deficiencies — not for routine lawn fertilization.
When to Use 0-46-0
Soil test indicates low phosphorus (P)
Establishing new seed or sod in deficient soils
Correcting long-term nutrient imbalance
Poor root development linked to low P levels
If your soil test does not indicate low phosphorus, this product is not necessary.
Why Phosphorus Matters
Supports strong root development
Aids in energy transfer within the plant
Improves early establishment of new turf
Helps young seedlings develop faster
Unlike nitrogen, phosphorus does not create rapid top growth. Its primary role is below-ground development and plant energy support.
Application Rates
General correction rate: 3–5 lbs per 1,000 sq ft
Severe deficiency: Up to 5 lbs per 1,000 sq ft
Incorporate into soil when possible for best results. Water in after application.
Important Considerations
Many states restrict phosphorus application unless a soil test confirms deficiency.
Not intended for routine maintenance applications.
Do not overapply — excess phosphorus does not improve turf quality.
For ongoing lawn maintenance, consider a balanced fertilizer program. If you are establishing new seed, our Starter Fertilizer 15-20-10 provides phosphorus along with nitrogen and potassium for early growth.
