These tests includes the standard Mehlich 3 (or AA8.2) soil test, plus the saturated paste test, along with an additional test for soil reserves of Co, Mo, Se and Si and the electrical conductivity (EC) of the soil as well as ammonium nitrogen and nitrate nitrogen.

How does it work? When your order is complete we email you a form to send with your soil sample. You will need to sample your soil (here’s how to take a soil sample) and mail the sample to Logan Labs. Logan Labs will test the sample and we will email the soil test reports to you.

If you irrigate more than 50% of the time, we recommend that you also include an irrigation water sample to be used in the saturated paste test (the test for soluble minerals).

How long does it take? It usually takes 3 to 5 working days after your samples arrive at Logan Labs before you receive your soil test reports. In the spring the lab is busier and it may take longer. Logan shuts down for major holidays and the week between Christmas and New Years.
