Quick Summary

Mole drainage is a method used in agriculture to remove excess water from heavy farm soils, particularly those with a consistent slope. It involves creating underground channels using a "mole plow". These channels act as drains, drawing water away from the farmland. This process is a form of land reclamation, aiming to improve soil conditions for more intensive agricultural use by managing excess water. Mole drainage is particularly useful in areas where surface drainage is difficult or where maintaining open ditches is impractical.123
