Indicators of salinity
Indicators are signs or symptoms that suggest salinity might be affecting a site. There are many different indicators for salinity and some common examples include:
- Areas becoming bare and 'scalded'.
- A white salt crust on brickwork.
- Changes in crop health.
- Seepage areas in roads.
- Patches of salt-tolerant plants developing.
- White crusts on soil surface when dry.
- Corrosion of water, gas and sewerage pipes.
- Tree decline or unhealthy grasses and shrubs.
Indicators are not always easy to detect and may take several years to emerge as a full-blown salinity problem. Some salinity indicators may be similar to those caused by other problems, for example, tree dieback may also be caused by non-saline waterlogging, insect attack or fungal diseases.
Site specific investigations can confirm the presence and severity of salinity. Techniques for measuring and assessing salinity are briefly explained in 'measuring salinity'
