Soil Analysis

To help identify the nutrients offered to the crop. Send in your samples or order sampling through us to analyze your soil properties.

Available Soil Tests:

S01 (Basic Soil Test)

S03 (Basic plus Micro-nutrients)

S04 (Basic, Micronutrients, and Organic Matter)

PSNT (Pre-Sidedress Nitrogen Test)

Bray 1 Equivalent

Ammonium Acetate

Estimated Element test performed with Mehlich 3 Extractant

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.

A: We strive for 5-10 days from order to collection and soil results received from lab and delivered to client.

A: Results can be sent to you via a CSV or PDF via email.

In some regions, results can be accessed through an online portal

A: OM, pH, Buffer pH, CEC, P, K, Mg, Ca, K%, Mg%, CA%

A: We sample fertility at 6” and have the capability to go down to 24″ with options to sample to 3′ (1-meter)

A: Grid, SoilOptix and Tissue sampling

A: Soil sampling can tell you a lot about what is happening in the field. It can answer questions on yield impact and how much fertilizer do you actually need to put down and where. Depending on the level of sampling being completed you can see what your macronutrients, micronutrients and even water holding capacity, just to name a few. 

South Dakota’s  soils can vary widely within a single field. Consider the topography, drainage patterns, and historical land use when determining sampling locations.

Different crops may have varying root depths, so it’s essential to sample at the appropriate depth. For row crops like corn and soybeans, sampling depth is typically 6-12 inches.

The timing of soil sampling can affect nutrient levels. Ideally, samples should be taken in the fall after harvest or in the spring before planting to reflect the nutrient status before the growing season.

Align soil testing with nutrient management plans. Consider the specific nutrient requirements of the crops to be planted and adjust fertilizer recommendations accordingly.

Soil pH is critical for nutrient availability. Test and address pH levels, as they can influence nutrient uptake by plants.

South Dakota’s soils vary in organic matter content. Consider this when interpreting soil test results, as organic matter influences nutrient retention and availability.

South Dakota has a significant focus on nitrogen management due to its impact on water quality. Assess nitrate levels in the soil and implement best management practices to minimize nutrient runoff.

A: Soil Test Reports are sent in CSV, Excel and PDF format.

A: No, not for fertility sampling. All you need to get started is a rough boundary of the field (we can provide) to be sampled.

A: You can call us if you have any questions about your soil test report.


A: Nutrient recommendations need to be requested when ordering soil sampling. If not, they can be added on after the field is sampled. The lab will need previous crop, Intended crop and yield goal.
