A field monitor that reads the living soil — carbon, moisture, biology — so regenerative farmers can watch the ground get better, season after season.

01
How it works
Three steps. No agronomy degree required.
/ 01
Bury a probe
A LOAM probe goes in the root zone and reads carbon, moisture, and respiration every 15 minutes.
/ 02
Read the biology
The soil food web — microbes, fungi, worms — is scored into one living index you can watch move.
/ 03
Grow the soil
See which cover crop, rotation, or amendment moves the number, season after season.
02
Everything but the guesswork
Farm the soil, not the forecast.
Live field telemetry
Moisture, temperature, and respiration from the root zone, streamed every 15 minutes.
Carbon accounting
Soil organic carbon, measured and trended — export-ready for carbon buyers.
Biology scored
The food web distilled into one living index, 0–100, you can watch change.
Cover-crop planner
Match the right cover to your gap, and see what it gives back.
Rotation memory
Every field remembers its own history, year over year, crop over crop.
Field weather
Frost windows and rain for your exact field, not the nearest airport.

Four floors of soil
Dig down. It's all alive.
A soil profile, top to bottom. Every horizon has a job — and a signature color. Hover a layer.
Oorganic0 – 5 cm
Fresh litter and humus. The roof of the soil, where everything begins to rot into tomorrow's topsoil.
Atopsoil5 – 30 cm
The engine room. Roots, earthworms, and the microbial bloom that turns dead rock into living ground.
Bsubsoil30 – 80 cm
Clays and minerals washed down from above. Where deep roots mine water and locked-away nutrients.
Cparent material80 – 120 cm
Weathered bedrock. Not dead — just patient. The slow pantry that feeds every layer above.

The slow plow
One pass, one frame at a time.

Four crops
The rotation decides the mix.
staple
Wheat
Pays the bills and leaves the cleanest straw on the farm.
spring
fast cover
Oats
Up in days, blankets a bare field before the wind gets it.

N-fixer
Clover
Pulls nitrogen from the air and leaves it in the ground, free.

From the desk of Ezra Voss
Most tools show you the crop. Loam shows you the ground it grows in.
I spent ten years farming the same forty acres my grandfather broke with horses. Same seed, same rain, and every year the soil gave a little less. It took me too long to realize we were measuring the wrong thing.
The crop is the receipt. The soil is the bank account. You can read the receipt every harvest and still go broke, because you never looked at the balance underneath.
So here's the invitation: put a probe in the ground, and watch the balance move for the first time. That's the whole product.

"I've tried every soil test on the market. Loam is the only one that shows the biology, not just the chemistry."

"The carbon number is the one that sold me. I can hand a buyer a page and the number's already moved."

"I set it on my late grandfather's field. Watching the index climb is like watching him nod."

The roadmap
Where we're going.
Q3 2026
In-ground probes + living-soil index, live in beta on 40 farms.
Q4 2026
Carbon accounting export and the cover-crop planner.
Q1 2027
Field maps drawn from your own probes, not a satellite guess.
Q2 2027
loam hardware: a probe that runs a full season on one charge.

Questions, answered.
How does loam read soil biology?+
Respiration — the CO2 the food web exhales — is the best single proxy for life in the soil. We measure it, then fold in microbes, fungi, and worm casts into one index.
Does it need a signal?+
Yes. The probe streams to your field page. No signal, and it buffers locally until the next connection.
Is it just for row crops?+
No. Orchards, pasture, and market gardens all read the same ground. The index doesn't care what you grow.
Is it free?+
Yes — the field monitor and living index are free during beta and stay free after launch.
Do you sell my soil data?+
Never. Your field's readings are yours. We don't sell, share, or even look at them beyond keeping the service running.
Can I export my carbon number?+
Yes — a verified, export-ready report, so a carbon buyer can trust the number the same way you do.
The soil is already talking.
