Meaning and Definition

A subsoil drainage channel created by pulling a pointed metal cylinder (a mole) through the soil, leaving an unlined tunnel for water to flow.

The process, technique, or resulting channel of draining heavy, impermeable agricultural land using this specific tool.

Dialectal Variation

British vs American Usage

Differences

The term is more common in UK/Commonwealth agricultural contexts. In the US, 'subsurface drainage' or 'tile drainage' is often the broader category, with 'mole drainage' specifying the technique.

Connotations

Both varieties treat it as a precise technical term for a specific drainage method. The UK usage may imply heavier clay soils typical of its farmland.

Frequency

Slightly higher frequency in UK agricultural discourse; in the US, it is known but less commonly referenced outside specific regions or specialist literature.

It is a common and traditional practice in areas with heavy, impermeable soils, such as parts of the UK, New Zealand, and the US Midwest, but is a specific technique within broader agricultural drainage.
