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.

Q&A
- How much of 0-46-0 phophate fertlizer needs to be added to a 32lb bag of 20-0-9 to increase analysis to 20-4-9? Thank you, Mike
- Mike, This product would need to be applied separately. How many lbs of phosphorous do you need to apply?
- Do you offer in 50 lb bags any a more realistic price? For garden use
- We currently only have this product available in 15lb bag size.
- When is this back in stock? Would like to order enough to cover half an acre and raise phosphate to high end of 50-110 from soil test.
- It will be back in stock today. You would need 45 lbs to apply 1lb of phosphorus on your 21,000 sqft lawn
- How long should pets stay away from lawn after application?
- Here are some tips to keep your pets safe when using any fertilizer: Wait longer than recommended: Wait two or even three days before allowing a pet to access an application area ' even for those products that claim a pet can be allowed back onto a lawn immediately. Several users of lawn fertilizers labeled as pet-safe noted issues with their pets coming into contact with the product. Watch your pets: It goes without saying, but keep pets away from treated lawns, plants, or soil until completely dry, and watering down pets can help reduce their exposure to fertilizer.
