What does the soil actually do?
CEC, organic matter, and drainage tell us more than a county average. We use multi-year imagery and your soil tests when they exist.
Genetics for Lee County
Dyna-Gro®, Proven®, and a full bench of regional genetics. We place hybrids and varieties by soil, drainage, and how hard you push nitrogen — not by what is left on the pallet.
The Steward seed desk
Northern Illinois is not one yield environment. Sand streaks, tight clay, and tiled black ground sit in the same section. A Steward consultant walks those differences before a bag is tagged to a field.
How we pick
CEC, organic matter, and drainage tell us more than a county average. We use multi-year imagery and your soil tests when they exist.
A racehorse hybrid on a maintenance nitrogen rate is a disappointment. We pair genetics with the nutrition page, not against it.
Gray leaf spot, SDS, white mold, and tar spot change the conversation. Protection programs start at the seed treatment bench.
Maturity spread is a logistics tool. We build a field-by-field calendar so the dryer is not the bottleneck.
On the bench
| Line | Role at Steward | Notes |
|---|---|---|
| Dyna-Gro® Seed | Core proprietary genetics | Exclusive retail |
| Proven® Seed | Selected rotations and mixes | Proprietary |

Availability moves with the season. Call the branch before you lock a whole farm to a single bag tag.
A 20-minute seed conversation at 1793 Steward Rd often saves a 20-bushel argument in October.
