Soil Detective

Olympia, Washington

Your soil is alive.
Understand it.

A chemical test tells you what is sitting there. We look through a microscope at the organisms doing the work — and show you what to do about it.

Health checks from $45 · Full biological analysis $159

Test it. Feed it. Learn it.

Most people arrive with one tired garden bed and a question. Any of these three is a fine place to begin.

Dirt versus soil

Dirt grows tired.
Living soil grows life.

Bagged dirt and dump-truck fill are mostly mineral. They hold water badly, they compact, and they need feeding forever. Living soil holds itself together — bacteria, fungi, protozoa, and nematodes cycling nutrients into your plants without you buying them by the bottle.

  • Nematodes Grazers that unlock nitrogen
  • Fungi Structure and long-term carbon
  • Protozoa Release plant-available nutrients
  • Roots Feeding the whole system sugars
