Establishing salt-tolerant plants can improve salt discharge rates and improve soil health. Improvements undertaken at a catchment scale bring many benefits, not the least of which is providing for increased agricultural and associated regional productivity – using water for production that otherwise would contribute to an environmental problem.
Salt export will greatly exceed salt import, so that with the same drainage fraction a rapid desalinization occurs. After one or two years, the soil salinity is decreased so much, that the salinity of the drainage water has come down to a normal value and a new, favorable, equilibrium is reached.
The salt flats of Abu Dhabi are a typical example of this, with the evaporation of water occurring from the capillary fringe - a subsurface layer where groundwater seeps up from a water table - which intersects the surface. This activity has contributed to the creation of an expansive salt flat, covering approximately 36,000 square kilometers.
Soil salination is the accumulation of free salts to such an extent that it leads to degradation of the agricultural value of soils and vegetation. Consequences include corrosion damage, reduced plant growth, erosion due to loss of plant cover and soil structure, and water quality problems due to sedimentation. Salination occurs due to a ...
Salinity (/ s ə ˈ l ɪ n ɪ t i /) is the saltiness or amount of salt dissolved in a body of water, called saline water (see also soil salinity). It is usually measured in g/L or g/kg (grams of salt per liter/kilogram of water; the latter is dimensionless and equal to ‰).
This will reduce the average American’s sodium intake to about 2,750 mg per day—still higher than the recommended amount, but a big improvement that could result in large public health benefits.
Khewra (Punjabi / Urdu: کھیوڑہ) is the second most populated city of Jhelum District and the neighbor city of Pind Dadan Khan in Jhelum District, Punjab, Pakistan. [1] The city is administratively subdivided into two union councils [1] and is the location of the Khewra Salt Mine. The population of Khewra city is about 35,000 (or 80,000).
