Data that spends money wisely.

Soil analysis, field mapping, variable-rate application and yield monitoring — wired back into your seed and fertility plan, not left as pretty colors on a screen.

Management zones

Three zones. Three different plans.

Zones are drawn from soil grids, yield history, elevation and imagery — then every input rate, population and timing decision is made per zone.

A
High-CEC flatsPush population, full-rate N with stabilizer.
B
Sand ridgeDrop population 10%, split nitrogen, watch K.
C
Tiled drawLater hybrid, fungicide priority, no fall N.

Services

Everything from probe to prescription.

Soil sampling

Grid (2.5 ac) or management-zone sampling with GPS-logged cores. Results come back into the same file as seed and fertilizer — not a PDF that dies in email.

Tissue testing

In-season tissue at V6, VT and R3 — the growth stages that actually change a pass. Results in 48–72 hours.

VRA prescriptions

Variable-rate lime, P, K, nitrogen and seeding prescriptions exported straight to your monitor or our applicators.

Yield analysis

Yield-monitor calibration and cleanup so next year's zones are based on signal, not noise. Multi-year profitability maps by zone.

Consulting

Data without a person is wallpaper.

Steward agronomists walk fields, argue with the map and sign the recommendation. Precision is a tool. The judgment is still human — and local.

Get started

Fall sampling window is open now.

Ground is easiest to probe after harvest. Book grid sampling this fall and the prescriptions are ready before spring.
