Mason jar soil layers — plain-language read

Enter approximate % sand / silt / clay from a settled mason jar (or pick a preset). You get a calm read: drainage, what to amend, crop matches, and what the jar test does not tell you (pH, contaminants, fertility). No account. No email. Runs in your browser.

Honest limit: for food gardens on unknown urban lots, follow the jar with a basic Extension / lab soil test. Texture is only one layer of the story.
