Four floors of soil

Dig down. It's all alive.

A soil profile, top to bottom. Every horizon has a job — and a signature color. Hover a layer.

Oorganic0 – 5 cm

Fresh litter and humus. The roof of the soil, where everything begins to rot into tomorrow's topsoil.

Atopsoil5 – 30 cm

The engine room. Roots, earthworms, and the microbial bloom that turns dead rock into living ground.

Bsubsoil30 – 80 cm

Clays and minerals washed down from above. Where deep roots mine water and locked-away nutrients.

Cparent material80 – 120 cm

Weathered bedrock. Not dead — just patient. The slow pantry that feeds every layer above.
