Free soil testing

Know what is in your soil.

We test yards, gardens and lots on free test days across the Sable Hills. You tell us where; we take the cores and send them to an outside lab. The result goes to you, and to nobody else.

How it works

Three steps, and nothing to pay.

1

Ask

Send the form below: where the property is, what kind of ground, and a day that suits. We never ask about anyone’s health.

2

We take the cores

On the test day our crew takes several cores from the top four inches, mixes them per area, and sends them to an outside lab.

3

You get the result

The lab sheet goes to you only, with our guide to reading it and the numbers for your county health department.

On the calendar

Next free test days.

Past days drop off this list by themselves, and a full day stays listed as full.

Ask for a test

Tell us where.

Two minutes. The form asks about the ground, not about you or your family.

What we never ask

Anything about health, symptoms, income, immigration status or insurance. None of it changes the test, so none of it is on the form.

Rather do it yourself?

Our guide shows how to take a sample and where to send it, in English and Spanish.
