Stones and wood

# Petrified wood

Wood that turned to stone but kept its grain, banded in shades of brown.

## What the simulation uses

- Holds water: 1 % by volume (Water it keeps after draining; the rest runs down to the drainage.)

- Pore space: 3 % by volume (Room for air and water between grains; low means roots suffocate when wet.)

- Weight: 2550 g/L (How heavy a litre is.)

- pH: 7 to 7.5 pH (How acid it keeps the soil.)

## Description
Wood that turned to stone but kept its grain, banded in shades of brown. It is dense, holds no water and stays neutral in the jar.

Also called fossil wood.

Estimated, where sources were thin: look authored for the app; physical values estimated.
