A Guarantee for Any Plan

Sound products benefit crops in many ways. No matter how you use them, we have a guarantee that will keep you covered.

Fertilizer Reduction

The Fertilizer Replacement Guarantee

We offer an ROI guarantee covering up to $100 /​ac for corn growers with an NUE ≥ 0.9 who use SOURCE DC to reduce 25 lbs of nitrogen and/​or phosphorus fertilizer. Growers can now save money and optimize their fertilizer application without risking yield.

Eligible growers purchase and apply a minimum of 4 gallons of SOURCE DC in Season 2024 (512 acres at labeled rate and timing). See download for full program details.

Eligible Crops: Corn at NUE ≥ 0.9

Real Money in Your Pocket

Sound guarantees are based on actual yield, not less reliable production metrics like tissue samples. Backed by over seven years of field testing and strong venture support, our performance guarantees are unmatched. We confidently take on the risk, ensuring you either have a great experience or get your money back— no one else offers that level of assurance.

ROI protection

The Yield Performance Guarantee

For growers using Sound products along with their standard fertilizer plan to maximize yield potential, we offer a financial refund up to 1x if return on investment (ROI) from increased yield does not offset the price paid by the grower. 

This guarantee is applicable for growers that apply SOURCE or SOURCE+BLUEPRINT stacked while maintaining their current nitrogen and phosphorus application practices. See download for full program details.

SOURCE only: Grain Corn (NUE at or below 0.89 lb/​bu), silage corn (V4 application),soybeans, cotton, wheat (HRW, SRW, HRSSW)
