When it comes to soybeans, most growers are confident in their routine — same seeding rate across the board, fertility program dialed in, and maybe some tweaks based on yield maps or field history. But despite that effort, soybean yields still swing — not just year to year, but acre to acre.
The frustrating part? It’s not always clear why.
The answer usually comes down to one thing: environmental variability. And when we say “environmental variability,” we mean the environment within the soil profile.
Different parts of the field retain or shed soil moisture differently, have varying levels of organic matter and can vary significantly in terms of slope (or elevation). But most soybean crop management strategies ignore these differences — and that’s where ROI starts slipping through the cracks.
As our Chief Science Officer Jon Fridgen explains:
“You can’t manage soybeans the same way across every acre and expect uniform results. Some environments need more seed to maximize node development, others less. It’s all about how that plant responds to the environment it’s in.”
If you’re flat-rating your soybean program across a 1,000-acre farm, you’re almost certainly over-investing in some places, under-investing in others — and leaving a significant amount of yield potential unrealized.
Precision ROI — Letting the Environment Lead the Way
At Advanced Agrilytics, we treat soybeans like the high-potential crop they are — and we manage them with the same environmental intelligence as corn.
We use spatial layers that go way beyond traditional field maps — because your field isn’t one flat, uniform landscape. Every acre responds differently to weather, fertility, and planting decisions, and managing for average just doesn’t cut it. These environmental layers help us tailor recommendations that fit how your field actually behaves:
- Soil Wetness Index (SWI): Identifies how water moves and holds across the field, helping adjust seeding rates and input timing to optimize plant growth and production, even in areas prone to over-saturation or drought.
- Organic Matter and CEC: These factors influence the soil’s nutrient-holding capacity and productivity potential, which, in turn, affect fertility and seeding decisions.
- Elevation and slope: Topography affects water runoff, erosion risk, and nutrient mobility — factors that are especially important for managing soybeans in areas with knobs or hills, or other terrain variations.
- Yield potential, node development, and VPI (Variety Profile Index): These factors help us understand how different environments build yield — whether through the main stem or branching — and guide decisions on seeding rate and variety selection.
The goal? Maximize each acre’s ability to deliver yield — and avoid wasting inputs where they won’t pay you back.
With that information, we write soybean seeding prescriptions that are tailored to maximize ROI per environment — placing more seed in areas where plant attrition is high or where node development needs a boost and decreasing seeding populations where fewer seeds can still maximize output.
“When you know which areas are prone to lodging and which ones struggle with early-season vigor,” says Fridgen, “you can tailor your strategy to give each acre what it needs — not what it doesn’t.”
And it’s not just about seeding. Fertility, too, plays a massive role in soybean ROI. Water-limited acres often require a different potassium and phosphorus strategy than stable zones. When you build those fertility plans by environment, not by flat rate, you stop overspending — and you stop underfeeding the areas of the acre that actually need it.
The Results — Smarter Soybean Strategy, Better ROI
Here’s what growers are seeing when they take a spatial approach to soybean management:
- 3.5x ROI by Year 4, with gains growing over time
- $46/acre more by Year 4, and up to $61/acre by Year 10
- Historically low-yielding soybean zones improved by up to 4.7 bu/ac, helping stabilize whole-field performance
These aren’t theoretical numbers — they’re results we’ve seen across the Midwest by helping growers manage soybeans at the sub-acre level.
“When you align your agronomic strategy to the environment, soybeans become a crop you can count on for consistent ROI,” Fridgen says. “It’s not about throwing more seed or more fertility at the problem — it’s about placing every dollar where it can go to work.”
