Mapping ROI of Biostimulants Applied During Corn’s Early Vegetative Stages (V2–V7) Across the U.S.
When growers evaluate new crop protection or biostimulant products, yield advantage is usually the first metric that comes to mind.
But yield alone doesn’t tell the whole story. The true measure of a product’s value is Return on Investment (ROI) — how yield gains translate into financial returns once input costs and grain prices are accounted for.
In our INNOVA modeling, we map field-scale ROI for all products we test. In a recent analysis for foliar-applied biostimulants across the U.S., we focused on ROI for stress-reduction treatments made during corn’s early vegetative stages (V2–V7).
What stands out in the data is that ROI clusters geographically — it’s highest where drought stress is most intense. Regions with mild stress show yield advantages, but the effect rarely translates into positive ROI. In contrast, across highly stressed landscapes from Texas through southern Illinois, where drought pressure peaked during the 2024 season, we recovered ROIs between 5–15%.
In these zones, even small stress reductions led to meaningful yield gains and financial returns — reinforcing that context matters as much as product.
ROI provides growers and retailers with a common benchmark for evaluating economic efficiency. In practice, an ROI above 5% is often needed to justify the additional time and expense of a treatment, though thresholds can range from 3–10%, depending on scale and commodity prices. By combining ROI, yield advantage, and environmental risk, we can identify where biostimulants deliver consistent economic value — and where they don’t. And because we model ROI mechanistically, we can tell you why.
