Fertility Soil Sampling | Country Roads Ag

The Details

Reliable data starts in the field.

When fertility decisions depend on the quality of the sample, the fieldwork matters. Country Roads Ag delivers fertility soil sampling across the Midwest with a focus on consistency, efficiency, and communication so your team can spend less time chasing details and more time using the data.

We work to support sampling programs that are organized, timely, and dependable. Whether you are managing seasonal volume, supporting grower relationships, or building recommendations across a broad Midwestern territory, we help keep the process on track.

Built around your program — not a one-size-fits-all approach

Every operation is different. Some partners need boots on the ground for sample collection and nothing else. Others want a more complete solution that includes lab coordination or extends all the way to fertility recommendations. We work with you to scope the right level of support — no more, no less.

Who this service is built for

Fertility soil sampling is a foundational step in agronomic planning. We work with ag retailers, independent agronomists and consultants, large growers, and teams managing seasonal sampling volume who need dependable logistics and clear communication throughout the process.

What to expect

When you work with Country Roads Ag on a fertility sampling program, you'll get a team that shows up prepared, samples with care, and keeps you informed from start to finish. Our process is built around your timeline and goals, not ours.

How We Work With You

Choose the level of support that fits your operation.

We don't lock you into a single model. Whether you need sample collection only or a full-service program from field to recommendation, we'll build the right scope around your needs.

Option 01

Sample Collection Only

You handle the lab and the recommendations — we handle the fieldwork. Reliable, consistent sample collection delivered to your specs.

Professional field sampling to your protocol
Samples delivered to your designated lab
Clear communication and project tracking
Scalable to your seasonal volume

Option 02

Sampling + Lab Coordination

We handle both the field collection and the lab relationship — streamlining the process so you get results faster with less to manage.

Field sampling plus coordinated lab submission
Work with your existing lab or we'll recommend one
Consolidated communication on field and lab status
Results delivered in your preferred format

Option 03

Sampling Through to Recommendations

A more complete solution — from sample collection through lab analysis to fertility recommendations your team can act on.

End-to-end program management
Lab coordination and results review
Fertility recommendations based on your goals
Ideal for retailers, consultants, and larger grower programs

Already have a lab relationship? Great — we'll work with them. Don't have one yet? We can help you find the right fit. Our goal is to make the process easier, not to add complexity or lock you into something that doesn't serve your operation.

What You Get

Deliverables that tie directly to your ground.

Sampling is only useful when the output is. Our work lands in your hands as georeferenced sample maps, field-level fertility layers, and variable-rate prescriptions ready to load into the cab. Below are a few examples pulled from a real field.

Georeferenced Sample Points

Sample locations tied to coordinates

Every sample we pull is GPS-tagged. You get a field map showing exactly where each point was taken, with the underlying lab data attached — so recommendations can be traced back to a specific spot on the ground.

Nutrient Layer

Interpolated fertility heatmaps

Point data interpolated to a full-field layer — phosphorus, potassium, magnesium, calcium, pH, organic matter, CEC, and more. Shows you where the field is short, where it is strong, and where variability is worth paying attention to.

VRT Prescription

Variable-rate scripts ready for the cab

Lime, DAP, MAP, potash, and custom blends built as variable-rate prescriptions tied to your yield goal, crop rotation, and preferred rec equation. Exported in formats your controller can read — no retyping, no translation.

Fertility Rx

Rotation-aware recommendations

The same soil data drives different scripts depending on your plan — corn-on-corn, corn-bean rotation, soybean year, or a custom program. You get the Rx package you actually need, not a generic blanket rate.
