Grid Soil Sampling

Because standard grid sampling has been around since the 90’s, it remains the most familiar method of soil sampling. It offers consistency in sample results to those growers who have utilized their previous GPS sample points over the years to return to the same locations for collection. We offer all grid sizes, including: 1, 2.5, 3.3, 4.4, 5, 10, and 20 acre grids.

Smart Grid Program

The Smart Grid soil sampling program provides increased accuracy by utilizing soil types or EC data to determine better placement of soil test sites within a field. By increasing soil test accuracy, we increase value.

Grid Size

Point placement is determined by grid size and soil types or Veris® EC data


All Soil Types

All soil types are represented in each field and so is each grid area


Accurate Samples

Decreases the chance of mixing different soils with varying properties

Increased Value

Increases the value of soil testing while using an industry recognized standard

Smart Zone Program

The Smart Zone Program provides an extremely intricate soil sampling method by collecting several cores from a small area that have the same soil properties and yield capability, making the soil samples as accurate as possible.

Zone Sizes

2 zone sizes offered (5-6 acre/zone average and 8-10 acre/zone average)


Many Data Layers

The Program utilizes many data layers to give you a true picture of your soil


Fast Previews

Customer may preview the zones before sampling is completed

Several GPS Points

Several GPS points are logged inside each zone for future sampling reference, representing the entire zone area

Nitrogen Management

Our approach to nitrogen management is utilizing actual, recent data versus deriving decisions based from modeling programs.


12 inch soil sample taken right ahead of side-dressing. Done on a grid basis (typically 4.4 or 10)

Core Collection

Cores are collected methodically on every sample to obtain consistency across the rows

Minimize Rain Events

Sampled about 5 days before expected side-dress application to minimize rain events between sampling and application time

End of Season

Samples are collected after corn is blacklayer. Test results indicate how much nitrogen was available to the plant

Veris EC Mapping

We utilize Veris® Technologies Soil EC mapping systems to identify soil zones. This one time investment is a powerful tool that can preface both our Smart Grid and Smart Zone programs for determining placement of more accurate soil samples.

Spring Soil Sampling

We strive to provide accurate and cost-effective soil sampling programs for our customers. Spring season soil sampling has been proven to show many advantages over fall sampling, providing a win-win situation for both supplier and grower.

Save Time

Time savings for grower and supplier-sample results received in the spring give a jump start on planning for fall fertilizer

More Consistent Samples

Samples are more consistent in spring because soil moisture tends to be present as opposed to a dry fall that can affect soil tests

Frozen Ground

No worry of sampling partially frozen ground in the late fall, or not being able to hand probe due to frozen soil

Recommended by Universities

Recommended by universities to allow crop residue to leach the nutrients back into the soil for more accurate results

RTK Boundary Mapping

We deliver RTK-level accuracy in the mapping of field boundaries and features. By using John Deere RTK Mobile cellular signal, we ensure high-accuracy GNSS positioning for +/- 1 inch repeatability year after year.

This precision takes on special significance for fields adorned with intricate waterways, terraces, and other internal features that demand meticulous mapping. Instantaneous uploading of fields to the My JohnDeere System streamlines accessibility and allows effortless sharing with your John Deere equipment. Alternatively, shapefiles can be exported for seamless integration into any GPS system.
