How healthy is your soil?

The Haney Test delivers the data you need to improve soil health.

Why use the Haney Test?

A living soil is an active soil. The Haney Test goes beyond other soil tests and tells you how biologically active or how alive your soil is. Tracking the biological activity of your soil over time tells you the health of your soil and indicates the availability of nutrients in your soil.

Why Ward Laboratories?

Ward Laboratories, Inc. has analyzed soil for the Haney Test since 2012 and is considered the industry leader in soil health testing. Our lab has been in operation for nearly four decades, and our team of soil scientists and laboratory professionals have countless years of education and experience.

How will improved soil health help me?

The goal is to produce soil that is alive and working with you in a holistic, regenerative way. Knowing the nutrient balance available to your crop is critical to improving yields and reducing the need for expensive inputs.

How does the Haney Test work?

The test measures and analyzes these key factors:

Soil respiration over a 24 hour period


Soil microbes breathe in oxygen and release carbon dioxide, similar to the way humans do. The Haney test measures how much CO2 your soil is releasing. Higher CO2 levels indicate more microbial activity.

Water extractable organic carbon and nitrogen


We’re looking for the amount of carbon and nitrogen that is available to crops and microbes. Knowing the raw amount of each nutrient present is just the first step – you want to know how much is actually usable. That’s what makes the Haney Test unique!

H3A extract


By using three naturally occurring  organic acids, the H3A extract mimics the rhizosphere altering action of plant roots dissolving soil minerals and liberating soil P.

Quickfire Q & A Time!

Q. How do I sample?

A. Click here to learn about sampling procedures!

Q. How often should I sample?

A. Sample before a management change is made and then an appropriate amount of time after that change was made.  This will vary by management practice and intensity of changes. Sampling pre-plant each year is a good starting point.

Q. When is the best time to take a sample?

A. The ideal soil temperature for sampling is 50 degrees Fahrenheit. In cooler climates, however, the soil temperature may not reach 50 degrees before planting. In that instance, we encourage you to take your sample during the pre-plant phase to aid in management decisions for the upcoming crop. Take samples during mild weather, and avoid sampling during extremes in either temperature or moisture. It’s imperative to stay as consistent as possible from year to year with sample timing and conditions.

Q. How much is this all going to cost?

A. At Ward Laboratories, the Haney test costs just $49.50! You will be sent an invoice with your sample results.

Q. Can I submit a sample from any location?

A. Yes, we receive samples from all over the world! Any samples that are submitted from outside the U.S. or in APHIS regulated areas of the U.S, however, will need an APHIS permit and label. You can obtain the APHIS permit here.
