Heavy soils, such as those found in the South West Irrigation Area SWIA in Western Australia require closely spaced subsoil drainage systems to provide sufficient water movement to control the effects of salt-waterlogging on pastures. This Bulletin reports the current best-bet' mole draining techniques gathered from observations over a number of years from several mole drainage systems. Includes legal considerations, principles of mole drainage, soil moisture and timing, mole plough design, mole leg, footnd expander design, collector drains, system design and costs.
