Mail us a scoop of your garden bed. We return a full-spectrum analysis of pH, nitrogen, organic matter, and microbial vitality — plus a season-by-season plan any gardener can actually follow.
Claim your first kit ↗Fourteen measurements from pH to cation exchange, rendered in plain language — not a lab printout you need a chemistry degree to decode.
Track every raised bed, orchard row, and container as its own living record. Watch your soil evolve across seasons and amendments.
Every report ends with a ranked list of exactly what to add, how much, and when — down to the bag of compost.
See how this year's numbers project into next year's harvest, so you spend on the amendments that actually move the needle.
Every sample you've ever sent, preserved in one timeline. Build a multi-decade record of the ground you steward.
Compare your dirt against thousands of gardens in your climate zone and know whether you're ahead of the curve.
Field reports
“I stopped throwing money at random fertilizer. Sorrel Furrow told me my beds were starved for potassium, not nitrogen — my tomatoes have never been this obscene.”
“As a first-time landowner I had five acres and zero clue. The bed-by-bed maps turned a decade of guesswork into a two-page plan I now follow like scripture.”
“The archived timeline is the killer feature. I can prove my no-till plot rebuilt three points of organic matter in four years. That's my legacy in a chart.”
