PPT-Water Logging & Salinity

Courtesy Prof Dr Habib ur Rehman Rise of water table is called waterlogging An agricultural land is said to be waterlogged when its productivity gets affected by high water table. November 2012 Salinity is a measure of the content of salts in soil or water. Salts are highly soluble in surface feature of vast areas of the Australian landscape, stored deep in soils or as surface GROUNDWATER INFORMATION SHEET Salinity Salinity is a measure of the amount of dissolved particles and ions in water. There are several different ways to measure salinity; the two most frequently use Observations: Ocean. Janice Bytheway . ATS786 . September 15, 2014. Disclaimer. I’m not an oceanographer.
