# Magnolia leaves

Big glossy leaves that hold up well in humid jars and break down slowly.

## What the simulation uses

- Holds water: 32.5 % by volume (Water it keeps after draining; the rest runs down to the drainage.)

- Pore space: 86 % by volume (Room for air and water between grains; low means roots suffocate when wet.)

- Weight: 60 g/L (How heavy a litre is.)

- pH: 5 to 6.5 pH (How acid it keeps the soil.)

- Mould risk: medium (How much fresh food it gives white mould; high-risk soils fuzz over in the first weeks.)

- Breaks down in: 1 to 3 years (How long it lasts before rotting down to fine soil.)

- Nutrients: low (Plant food it brings.)

- Presses down to: 40 % of its loose depth (How far pressing can pack it, keeping its weight.)

## Description
Big glossy leaves that hold up well in humid jars and break down slowly. Isopods especially like eating them.

Also called magnolia leaf litter.
