2025 Performance Guarantee
We developed the N-Physis Performance Guarantee to give farmers peace of mind as they experience the benefits of N-Physis.
N-Physis bridges the nitrogen gap in crops by delivering systemic nitrogen fixation precisely when and where it’s needed for optimal growth and yield all season long. It works—guaranteed.*
Applied in-furrow or as a foliar spray, N-Physis provides season-long nitrogen throughout the plant, including foliage and roots.
- In corn, N-Physis consistently delivers yield increases on average 6 bu/ac
- In soybeans, N-Physis consistently delivers yield increases on average 2 bu/ac
- In many other crops, N-Physis provides a similar return of 2-4X of your investment
We understand that adopting N-Physis on your operation means investing in a product and technology that may be new to you. To honor your commitment to giving N-Physis a try, we’re backing you with our Performance Guarantee.
Due to our extensive research, the N-Physis Performance Guarantee stands behind minimum yield increases on the following approved crops:
| Approved Crops | Minimum Benefit |
|---|---|
| Corn | 2.5 bu/ac |
| Canola | 1 bu/ac |
| Sunflower | 100 lbs/ac |
| Alfalfa | 0.5% CP or 10 pts. RFV |
| Rice, Wheat (including durum) | 2.0 bu/ac |
| Soybeans, Peas, Lentils | 1.5 bu/ac |
| Potatoes | 2.0 cwt/ac |
| Cotton | 15 lbs/ac |
If the N-Physis application does not yield the minimum yield increase on approved crops for any given field, YieldMaster Solutions will replace the product to the quantity used on that field.*
Conditions apply – see program terms and conditions.
*Program Terms & Conditions
- Purchase and apply at least 160 ac of N-Physis by July 15, 2025. Claim submissions with full documentation must be received via the YieldMaster Solutions website by December 1, 2025.
- Store N-Physis properly: Below 80° F, low humidity conditions and out of direct sunlight. Large temperature fluctuations should be avoided.
- Apply N-Physis on approved crops as an in-furrow or foliar application at labeled rates and per use guidelines. Seed treatments are not included.†
- A representative check strip within the same field as N-Physis is being applied is required. The check strip must represent the larger of either 10% of the applied acres of the field or 5 ac. The check strip must represent similar soil type and topography of N-Physis-treated areas of the field.
- Use a harvest monitor or weigh wagon to measure the yield of the entire N-Physis treated area in any given field against the full check area.
- For non-alfalfa crops, if the harvest monitor or weigh wagon does not show at least the minimum guaranteed yield increase for approved crops on the N-Physis treated area vs. the check area, YieldMaster Solutions will replace your N-Physis product applied on that specific field. Check strips are required on each distinct field that N-Physis is applied. Each field must be assessed and claimed separately.
- For alfalfa claims, follow trial and sample collection protocol and send in samples to a reputable lab. Sample data must be attached to claims submitted to YieldMaster Solutions.
- Apply within a registered US state.†
- N-Physis Performance Guarantee does not apply to extreme situations of crop failure. Any claimed field must have a check strip yield within 40% of established crop yield averages for the area.
- The N-Physis Performance Guarantee is limited to replacement product to the total amount purchased within the terms and conditions of the program.
