Soil Lab · Living soil, never dug

Look inside a no-till living-soil bed: the bacteria crowding the roots, the fungi trading minerals for sugar, the protozoa and nematodes that turn microbes into plant food, three kinds of earthworm, cover crops, mulch and the things growers add. Click anything to see what it does and how well the claims about it hold up, then dig the bed up and watch what breaks. Every line has its sources.
