Henri Bergson

Not Fertile

Subsoil is part of a sequence, typically found between topsoil and bedrock.

Soil Layers

Subsoil qualities can affect agriculture; rich subsoil promotes better crop growth.

Agricultural Quality

Recognize 'subsoil' usually references the more dense materials below the topsoil.

Clay and Silt

In construction, subsoil must be stable for a safe and solid foundation.

Construction Base

Challenges with subsoil, like rocks or water, can increase construction costs and complexity.

Foundation Challenges

Subsoil's toughness often necessitates specialized excavation techniques.
