## Question

Define soil fabrics and soil structure.

## Short answer

Soil fabric is the geometric arrangement and orientation of particles, groups, and pores. Soil structure is the fabric together with interparticle bonding forces.

## Answer

- **Soil fabric** is the geometric arrangement of soil particles, groups of particles (flocs) and pores in a soil mass, including orientation and shape (how the particles are packed).
- **Soil structure** is the combination of fabric and the interparticle forces between particles; it includes the fabric plus effects of cementation and bonding. Types include single-grained, honeycomb, flocculated and dispersed structures.

## Check yourself
