Real soil data for real growing conditions.

Most plant references say "well-drained soil" and call it a day. We're building something better — a crowdsourced database of real soil test results from real growing locations. Whether you're restoring a prairie, managing public land, conducting research, or just trying to figure out what to plant in your yard — real data beats guesswork.
