Know your soil, 10 feet at a time
A 10×10-foot soil map built from about 335 scan points per acre. FarmIQ turns it into variable-rate prescriptions your equipment reads.
How It Works
1. We Scan Your Fields
The scanner reads natural gamma radiation across every acre and tells us where to sample. We run the whole job.
2. We Build Your Maps
Scan data becomes 10×10-foot nutrient maps in FarmIQ, overlaid with your satellite and machine data.
3. You Get a Plan
Variable-rate prescriptions for seed, fertilizer, and amendments, built from your actual soil.
Prescriptions your equipment reads on day one
Every map underpins nitrogen monitoring, weed prescriptions, and year-over-year comparison.
Most draw zones, then sample them. We map in 10×10-foot pixels and only zone the prescription, so your controller can read it.
What We Map
Nutrients (N-P-K + micros)
Nitrogen, phosphorus, potassium, calcium, magnesium, sulfur. Optional micros: zinc, iron, manganese, copper, boron.
Organic matter + pH
LOI organic matter, pH, and buffer pH for lime. Tracked yearly, OM shows if you're building soil or mining it.
EC + CEC + texture
Conductivity, cation exchange capacity, and sand/silt/clay: why that northwest corner always runs dry two weeks early.
Prescriptions ran live in spring 2026
W02 field, 45 bu spring wheat target: a 10-zone phosphorus prescription loaded to Topcon TAP and run on the seeder the day the file arrived.
We've built prescriptions since the early 2000s. Since fall 2024, FarmIQ Soil RX replaces the hand GIS work, so every field gets a repeatable prescription.

Common questions
$12.50/acre for scanning and lab-analyzed samples, good for five crop seasons. FarmIQ Soil RX prescriptions are $0.50/acre per nutrient or $2.50/acre for all maps, unlimited runs per season. Most operations recover the fee in fertilizer savings the first season (full price list).
Almost any time: only big snow drifts or ice stop a scan, and frozen ground is fine. Crop/fallow, scan the fallow spring through summer; irrigated or recropping, right behind the combines.
PDF for review, shapefile for GIS, and ISOXML for the cab. Compatible with John Deere, Case IH, New Holland, Ag Leader, Trimble, Raven, Topcon, and any variable-rate-capable system. Tell us what's in your cab and we verify the format first.
Everything: the point-sample dataset, raster maps for each nutrient layer, shapefiles, ISOXML prescriptions, and a written agronomic summary.
