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.
