Dry Land Salinity
Salinity in drylands can occur when the water table is between two to three metres from the surface of the soil. The salts from the groundwater are raised by capillary action to the surface of the soil. This occurs when groundwater is saline (which is true in many areas), and is favored by land use practices allowing more rainwater to enter the aquifer than it could accommodate. For example, the clearing of trees for agriculture is a major reason for dryland salinity in some areas, since deep rooting of trees has been replaced by shallow rooting of annual crops.

The dry scent of a dying garden in September,
The wind fanning the ash of a low fire.
What I love is near at hand,
Always, in earth and air.”
—Theodore Roethke (1908–1963)
“Far out of sight forever stands the sea,
Bounding the land with pale tranquillity.”
