Mail-in land test kit · from $99

Know the land you've cared for like never before.

Composting, mulching, no-till, native plants—all of it is about the ground, and none of it says what's actually in it. One sample, read element by element in plain language. Every kit plants a tree. From $99.

Built for gardeners, composters, homesteaders and anyone who's been tending the same ground for years.

WHY UNDR

No expert required. Ten minutes, your own mailbox, nobody on your property.

No reading without a next step. What each number means, and what comes next if one stands out.

Unearth value. Gold, silver, platinum and the rare earths.

Private and confidential. We never sell your results.

Learn your land, and how to care for it. What it's made of, how it behaves, what it responds to.

A report you'll want to share. Plain English, your land's type, real comparisons.

Two things show up in the mail.

An open UNDR kit with the shovel, gloves, pouches and prepaid mailer laid out
First—the kit

Shovel, gloves, sterile pouches, prepaid mailer. Dig, seal, drop it in your own mailbox.

Then—the report

Your scoop, element by element, in plain English. Posts to your account days after your sample lands.

  • 1. Dig

    A small shovel and a card telling you how. Ten minutes. Gloves in the box, and the kids will want a turn.

  • Mail-in soil sample kit with envelope and test vials for home land testing

    2. Mail

    Receive your report and analysis in your UNDR account portal.

The ground sorted itself long before anybody planted anything in it.

Water came down the slope and dropped what it was carrying, and it did that for a few thousand years before the house was here, and that's why the low corner behaves differently than the high one. You've been working with all of that the whole time. Nobody has ever told you what it left behind.

Our sampling instructions put it better than we can: "Nature does most of the sorting work for you. Gravity, water, and time tend to drop their cargo in predictable places." Pick one of those places and we'll read what's in it.

What the report does. It tells you what's in the sample you sent and how each reading sits against common ranges. And it gives you catered guidance based on your readings.

What we go looking for
Precious metals
Rare earth elements
Oil
Heavy metal toxins
Petroleum contaminants
45 standard elements

Six categories of things we can look for. Your kit decides which of them get run, and the report says plainly what showed up and what didn’t.

The report

This is what comes back.

Not a lab printout. Real pages from real reports:

Your short answer

Two of ten heavy metals showed up, both under the common range. Your land reads Volcanic, and your iron is in the range of samples from Iceland.

One plain paragraph at the top, before any chart.

Carson and Mari, founders of UNDR
Why this exists

We built the lab because we couldn't get the answer either.

"What if?" is one of the most fun questions in life, and finding the answer should feel like an adventure. We built UNDR to be an experience you share with family.

Every sample is run here in the U.S., on the same instrument with the same protocol, and a person reads every report before it goes out.

"I have no idea where to start."

That’s the normal starting point, and the kit assumes it. A small shovel, a card telling you how, and a prepaid mailer are in the box. Ten minutes in your own yard, then your own mailbox. Nobody comes to your property.

"What if it comes back boring?"

Every one comes back with a type, a map, two famous comparisons and a page per element. If yours tells you nothing you didn't already know, email us and we'll refund it.

"What if it comes back high?"

Then you'll know. An elevated number comes with a name, the usual reasons it shows up, and who handles it. A number you never looked up gets none of that.

Pick your kit.

Every kit ships with the shovel, gloves, pouches, prepaid mailer and the full report.

FREQUENTLY ASKED QUESTIONS

Will this tell me what to feed my beds?

No—that's a fertility test, and your county extension office runs one for under $30. It's the right tool for that job. UNDR reads what the ground is made of: the metals and elements in the sample you send, which is a different question, and one nothing else answers for you.

Where should I take the sample from?

Wherever you've put the most work in, or wherever the ground has been doing its own. Our sampling instructions page starts with the idea that nature does most of the sorting for you—gravity, water and time tend to drop their cargo in predictable places—and then walks through the universal hot spots: the lowest part of your property, natural drainage paths, the base of slopes and hills, exposed rock or gravel patches, soil that looks different, old disturbed ground. The card in the box tells you how deep and how much.

Does it have to be my land?

Your yard, your parents' place, family land, or anywhere you have permission to dig.

How accurate is it?

Accurate for the sample you send. Lab-grade instruments, recognized methods, and every number shows its own detection limit and margin of error. One scoop doesn't describe a whole property.

When will I get my results?

Three to five business days after your sample reaches the lab, 1-2 on Premium. We post it to your account and email you.

What happens to my information?

We never sell your results.

Can I compare two spots, or the same spot later?

Each kit covers one sample, so two spots means two kits. Every sample runs on the same instrument with the same protocol, so two reports line up against each other.

You've been taking care of this ground for years, and it's been doing its half a lot longer than that.

One sample from wherever you've put the most work in, our own U.S. lab, and a report that reads element by element in plain English. And for every kit we sell we plant a tree, in partnership with Plant with Purpose. Kits from $99.
