Mole Drainage For Increased Productivity In The South West Irrigation Area, D L. Bennett, Richard George, Bill Russell
Mole Drainage For Increased Productivity In The South West Irrigation Area, D L. Bennett, Richard George, Bill Russell
Bulletins 4000 -
Heavy soils, with low rates of soil-water movement, such as those found in the South-West Irrigation Area (SWIA), require closely spaced (2-6 m apart) subsoil drainage systems to provide sufficient water movement to control the effects of salt-waterlogging on pastures. Such close spacing using traditional buried pipe or tile drainage systems is impractical. As a result, mole drainage systems, used in other parts of the world for over 50 years, have gained popularity in the SWIA in recent years.
This Bulletin Farmnote reports the current ‘best-bet’ mole draining technique for SWIA conditions gathered from observations over a number of years …
Dam Site Selection In The North-Eastern Wheatbelt, J L. Frith
Dam Site Selection In The North-Eastern Wheatbelt, J L. Frith
Journal of the Department of Agriculture, Western Australia, Series 4
Western Australia's wheatbelt farm dams are dug three to eight metres deep and are generally sited in soils which either are inherently impermeable or can be made so during construction.
In the eastern and north-eastern wheatbelt, however, only a small proportion of the soils meets these criteria. Dam site selection in these areas therefore depends on a good knowledge ofwhich soils aresuitable and on our being able to locate them efficiently by using surface indications such as surface soil, natural vegetation or topographic features.
