Soil testing

Know your soil.
Grow your best.

A chemical test tells you what nutrients are present. A biological test tells you whether anything is available to your plants — and what is missing from the system that would make it available.

Not sure which one

Which test do you actually need?

Start with the Health Check

If you have never had soil looked at biologically, start here. You get a clear 1–3 score for each group of organisms and a summary of what is working and what is not. It answers "is my soil alive?" without a stack of numbers.

$45

Step up to the full analysis

If you are making real decisions — a market garden, a restoration, a bed that keeps failing — you want the quantified version, with reference ranges for the specific crop you intend to grow and a conversation about what to do next.

$159

Order one test per unique area you want tested. Beds with different histories tell different stories.
