Depending on your answer, you’ll use 1 of our 2 soil sampling procedures.
Important: soil sampling procedure varies based on test type. Be sure to follow the directions for your test carefully.

Here are a few we’d recommend:
$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.
$80.00 USD
Click here to view more information about the PLFA test.
Another popular option, this test looks for phospholipid fatty acids, or PLFA. Analyzing PLFA gives you critical information about your soil’s microbial health. 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.
(Total bacteria (Gram (+), Gram (-)), Total Fungi (Arbuscular Mycorrhizae, Saprophytes) Protozoa, Undifferentiated Microorganisms)
$49.50 USD
One of our most requested tests, this unique process measures and analyzes biological activity in your soil and the availability of key nutrients. The Haney Test goes beyond traditional soil testing to assess the overall health and vitality of your soil.

$19.00 USD
(SAR, Electrical Conductivity, pH, Bicarbonate, Calcium, Magnesium, Sodium, Sulfur, Chloride)
$30.00 USD
$25.00 USD
The soil respiration test is a measure of the microbial biomass in the soil and is related to soil fertility and the potential for microbial activity.
$25.00 USD
(per enzyme, per sample)
Soil microbes create and release soil enzymes to aid in the decomposition of organic matter and promote nutrient cycling in the soil. Analyzing enzymes allows for earlier trends in nutrient cycling to be detected between different management strategies or year-to-year comparisons.
(β-glucosidase (BG) – Carbon Cycle, N-Acetyl-β-glucosaminidase (NAG) – Nitrogen Cycle, Alkaline Phosphatase (AlkP) – Phosphorus Cycle, Acid Phosphatase (AcP) – Phosphorus Cycle, Phosphodiesterase (PHD) – Phosphorus Cycle, Arylsulfatase (ARS) – Sulfur Cycle)
$20.00 USD
Permanganate oxidizable carbon (POX-C) is an analysis that quantifies the labile carbon in the soil. Understanding changes in soil organic carbon is an early indicator of impacts of soil management decisions.
$30.00 USD
This analysis measures how easily a soil aggregate breaks down when exposed to water, which provides information on the soil’s resistance to water and wind erosion.
(% Aggregate Stability, 1-2 mm fraction; % Aggregate Stability of Bulk Soil, 1-2 mm fraction)
$25.00 USD
The available water holding capacity (AWC) analysis quantifies the total plant available water a soil can hold and thus provide to a growing crop.
(Measured at Field Capacity (0.1 bar) and Wilting Point (15 bar))
$33.75 USD
The total nutrient digest analysis quantifies the total values of elements in a soil, which includes both plant available and unavailable nutrient pools.
(Carbon, Nitrogen, Phosphorus, Potassium, Calcium, Magnesium, Sulfur, Zinc, Iron, Manganese, Copper, Boron, Molybdenum)
