2026 Performance Guarantee

We developed the FORTRESS+ Performance Guarantee to give farmers peace of mind as they experience the benefits of Fortress+.

Fortress+™ is an optimized liquid biostimulant containing vinasse, amino acids and essential micronutrients, to enhance crops’ flowering periods and improve yield. Fortress+ contains bioactive compounds that activate specific metabolic pathways, especially important at the pre-flowering stage, to enhance yield by reducing flower abortion and mitigating abiotic stress.

• Stimulates plant metabolism to limit flower abortion and maximize yield
• Reduces the effects of plant abiotic stress including drought, frost & high temperature

We understand that adopting Fortress+ on your operation means investing in a product and technology that may be new to you. To honor your commitment to giving Fortress a try, we’re backing you with our Performance Guarantee.

Due to our extensive research, the Fortress+ Performance Guarantee stands behind minimum yield increases on the following approved crops:

If the Fortress+ 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 Fortress+ by July 15, 2026. Claim submissions with full documentation must be received via the YieldMaster Solutions website by December 1, 2026.
• Store Fortress+ properly: Below 80° F, low humidity conditions and out of direct sunlight. Large temperature fluctuations should be avoided.

• A representative check strip within the same field as Fortress+ 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 Fortress+-treated areas of the field.
• Use a harvest monitor or weigh wagon to measure the yield of the entire Fortress+ treated area in any given field against the full check area.
• If the harvest monitor or weigh wagon does not show at least the minimum guaranteed yield increase for approved crops on the Fortress+ treated area vs. the check area, YieldMaster Solutions will replace your Fortress+ product applied on that specific field. Check strips are required on each distinct field that Fortress+ is applied. Each field must be assessed and claimed separately.
• Apply within a registered US state.†
• Fortress+ 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 Fortress+ Performance Guarantee is limited to replacement product to the total amount purchased within the terms and conditions of the program.
