Underground Water Supplies In The Wheatbelt, T T. Bestow
Underground Water Supplies In The Wheatbelt, T T. Bestow
Journal of the Department of Agriculture, Western Australia, Series 4
Underground water originates from rainfall. The size of the underground recource in any region is broadly related to the amount of rainfall. However, rainfall intensity and seasonal distribution are just as importent as the quality. A relatively small annual fall which consists of a series of heasvy showers or storms close together, may be a more effective source of recharge to underground water than a larger fall that is more evenly distributed over a longer period.
A large annual rainfall, however, is no guarantee that underground water supplies will be readily available. This is because soils and the underlying rocks …

Hints On Irrigating Citrus With Saline Water, Stanley Thomas Smith
Journal of the Department of Agriculture, Western Australia, Series 4
IN the past few years a number of citrus orchards near Perth have shown signs of damage caused by excess "salt" (chloride) uptake. All have been irrigated either from the Canning River or from private bores or dams.
Senior Soil Research Officer S. T. Smith describes glasshouse experiments which have given some useful guides to minimising "salt" damage in citrus trees irrigated with low-quality water.

ALL natural water supplies contain dissolved salts. In wet climates these salts are usually not present in sufficient quantity to cause plant damage.
However, in Western Australia many natural water supplies contain harmful amounts of dissolved salts.

In Western Australia it is often necessary to use saline water for irrigation and gardening because of the lack of better water.
Two factors influence the results achieved. One is the selection of suitable plants, the other is the way in which the water is used.
