The phosphorus
you need is already
under your feet.
You have spent years building a phosphorus reserve your crop cannot reach. TriPhase™ frees that locked-up soil phosphorus and holds it available — so you can draw down what you already own instead of buying more.
Your soil test shows a sliver.
The rest is still down there.
A soil test measures only the small pool of readily available phosphate. The vast majority of the phosphorus in your ground is locked into mineral and organic forms your crop simply cannot get at — including hydroxyapatite, which a soil test never sees.
You already paid for it. Every year you applied more phosphorus than the crop removed, the difference went into that bank. TriPhase is built to make a withdrawal — which is why it is designed to replace part of your rate, not sit on top of it.
Release.
Capture.
Hold.
TriPhase isn't an additive. It carries two proprietary chemistries working as one circuit — one to free the phosphorus, one to keep it free long enough for the crop to use it.
Frees the P your soil is holding
Charge-release chemistry dissolves phosphate bound in soil minerals — the reserve that has been building in your field for years and never showed up on a soil test.
Switches on the plant's own uptake
Builds bigger roots and turns on the plant's natural phosphorus pumps and fungal partners — so the crop can actually go and get what's been freed.
NutriCharge® keeps it available
Freed phosphate wants to re-fix immediately. Patented charge-control chemistry holds it plant-available for months — through peak uptake and into grain fill.
Release without hold is a waste of time. Anything that frees soil phosphorus and then leaves it exposed just hands it straight back to the calcium, iron and aluminum that locked it up in the first place. The second chemistry is what makes the first one pay.
Most of the crop's demand
is still ahead of you at V10.
By the time corn hits V10 it has taken up only a fraction of the phosphorus it needs — and soil-available P is at its lowest point of the season. That is the window TriPhase is built for. Drag your program in and see what a sidedress application is working with.
Illustrative planning tool. Corn removal at 0.35 lb P₂O₅/bu (Tri-State 2020); roughly 75% of uptake occurs after V10. Soil bank estimate from total soil P in the top six inches — the fraction a soil test does not measure. Confirm all figures with your agronomist.
Fits the pass
you already make.
| How to use it | What it does |
|---|---|
| At sidedress | The primary use. Frees and holds soil phosphorus right as your crop's demand peaks — no new pass, it rides your nitrogen application. |
| On dry fertilizer | Coated onto the dry blend at 0.5 gallons per ton at the plant or retailer — the granule goes out treated, same rate, same pass. |
| With your starter | Run a lower starter rate and let TriPhase double what is actually available. One treated gallon performs like two to two and a half untreated. |
| In your program | Works into what you already run. No new equipment, no new pass, no new tank. |
| Rate philosophy | Designed to replace part of the traditional P rate by mining reserves already in the field — not to add another input on top. |
Every gallon stretches
One gallon of treated starter performs like two to two and a half gallons untreated.
The window it's built for
Sidedress delivers phosphorus right at peak uptake — a late start needn't cost the season.
Held, not just released
Charge control keeps freed phosphate plant-available for months rather than days.
Straight answers.
Is TriPhase a fertilizer?
Can I put it on dry fertilizer?
So do I still buy phosphorus?
How is this different from NutriCharge?
Why sidedress rather than at planting?
Isn't releasing soil phosphorus just a one-time draw?
Does it need warm soil like a biological?
