Vertisols have poor internal drainability when wet, requiring closely spaced drains for excess water removal. Mole drainage is a pipe-less drainage technology popular in UK, New Zealand and Australia. Its use in fine textured soils using standard mole ploughs is mainly confined to those countries where mole plough development took place. In India, few laboratory studies were reported apart from one field study at Digod, Rajasthan on mole drainage.
