Services | Soil & Soil Health Analysis

If your soil could talk, what would it say?

I’m healthy and thriving!

I’m starving! SOS!

Ward Laboratories can help you increase your soil’s productivity, microbial health and nutrient balance.

Looking to boost your dollars per acre at harvest time?
It all starts in the soil.

Your plants are only as healthy as the soil they’re feeding from.

Reduced microbial activity and limited nutrient availability can result in lackluster harvests. We’ll give you a complete report of our findings and recommend corrective measures.

Maintaining optimum soil health saves you money on expensive inputs.

How much money are we talking? Studies performed by Kastens and Dhuyvetter concluded that a farmer could save $4-5 USD per acre on fertilizer by relying on accurate soil testing reports. And when grain prices are low and profit margins are razor thin, soil testing becomes even more critical.

Curious about your soil’s health?

Here are three of our best-selling, comprehensive soil tests.

Routine Soil Analysis

$20.00 USD

The test that covers (almost) everything! We recommend this to everyone from commercial crop producers to home gardeners … anyone who needs to know what’s in their soil! This test measures pH, buffer pH, sum of cations (CEC), base saturation (%), soluble salts, organic matter, nitrate-nitrogen, phosphorus, potassium, calcium, magnesium, sodium, sulfur, zinc, iron, manganese and copper.

PLFA

$85.00 USD

Another popular option, this test looks for phospholipid fatty acids, or PLFA. Analyzing PLFA gives you critical information about your soil’s microbial populations. Environmental conditions such as temperature and moisture can alter this microbial community. Knowing how these changes occur over time gives our producers the ability to compare various management techniques and how they affect the health of these microbes.

Soil Health Assessment

$52.00 USD

Ward Laboratories, Inc. is now offering a new Soil Health Assessment (SHA) package. This test combines the latest in soil science, ensuring that both soil fertility and soil health are viewed through a single test, helping farmers and researchers measure and manage soil health without compromising productivity. Microbial activity and food are evaluated to provide data that enhances operations while also evaluating nutrients in a manner that is widely accepted by Land Grant University correlations and calibrations.

This new package also includes modified aggregate stability. With this addition, the new Soil Health Assessment offers two biological, one chemical and one physical indicator of soil health.

Soil DNA

$190.00 USD

Ward Laboratories, Inc. is now offering a new biological testing package. Through a strategic partnership with Trace Genomics, our customers now have access to nutrient cycling indicators, soil health indicators and pathogen analysis. This test utilizes whole genome sequencing, helping farmers and agronomists accurately identify biological threats and opportunities without compromising productivity. Trace’s use of industry-leading DNA sequencing, combined with their cutting-edge data analysis engine, is unmatched in agriculture and enables the most complete and detailed assessment of the soil’s capacity to cycle essential plant nutrients such as nitrogen and phosphorus. Measures of microbial biodiversity and oxygen availability, included in this new test package, also serve as important components in assessing the overall health of the soil.

Pathogen Analysis – detection and quantification of 170+ pathogens covering 70+ crop types.

Nutrient Cycling Indicators

Phosphorus – Phosphorus Mineralization Potential & Phosphorus Solubilization Potential

Nitrogen – Denitrification Potential, Nitrate Ammonification Potential & Nitrification Potential

Soil Conditions – oxygen availability & bacterial diversity

How Do I Take a Sample?

Click here for everything you need to know about sample types and sampling procedure!

Does Ward accept samples from any location?

Yes, we accept samples from producers all over the world! Any samples that are submitted from outside the U.S. will need an APHIS label. You can request the APHIS label by emailing sales@wardlab.com.

Can you test the soil in my lawn or garden?

Yes! We suggest one of two tests. For homeowners using conventional management practices (for example, synthetic fertilizers), we recommend our Routine Soil Analysis. For producers using natural approaches (for example, manure) a Haney Soil Health test may be beneficial.

What are crop recommendations?

Crop recommendations help producers understand how much fertilizer they’ll need to apply based on soil nutrient availability, the crop to be grown, and the anticipated yield.

How do i request recommendations on my soil test?

Please include the crop and yield goal for up to 3 crops. If you’re unsure of the yield goal, please provide information like geography, irrigation/rainfall, past crops, cropping systems, etc, that may be helpful in determining your goal.

Do I have to pay for recommendations?

No, recommendations are always free!

Are recommendations available for Haney tests?

Yes!

Can you input soil test results with my ag software?

Yes! We are integrated with many platforms already and are willing to connect with yours.
