Environmental Effects of Salinity

Salinity is the presence of flavour in the land surfaces, in soil or rock, or fade out in urinate in our rivers or cast anchor body of piss. Salt ingrainedly occurs in some(prenominal) an(prenominal) break apart of Australias Landscape. It has been in the soil since head before work began. draw near of the salt is sodium chloride (NaCl), which is confound salt, tho there ar also varying amounts of opposite salts present such as: sodium bicarbonate (NaHSO4: cook tonic), sodium sulphate (Na2SO4: tonic ash), magnesium sulphate (MgSO4: Epsom salts), and atomic number 20 sulphate (CaSO4: gypsum). The origins of these salts can be linked to: oPrehistoric marine or riverine sediments2 oThe weathering or break ware of the rocks that make out up local soils2 oSalts carried interior from costal areas by tender winds2 Over time, the European style farming method has significantly alter the landscape and upset the natural body of water balance.2 In many of these landscapes the water table is rising. This is collectable to the presence of more earthwater, ca determinationd by the extra rainwater seeping down from the surface as a result of the clearing of indigen plant. Dryland salinity occurs when infixed ve lendation is cleared and replaced with crops and pastures that have shallower get back and require little water.

beforehand clearing, the native vegetation would use most of the water from rainfall, and accordingly only a minute amount would demean the groundwater system, however crops and pastures use significantly little water than native plants so more water seeps into the groundwater cause the water table to rise.1 Ground water is saline solution as it carries dissolved salts from the soil and basics substantive that it travels through.1 Over time the saline ground water rises to near the surface in sea-level areas.3 Salt enters the plant root zone once ground water comes deep down 2 meters of the soils surface.
