Soil salt loss or leaching refers to the loss of soluble salt in soil due to natural or artificial conditions
Desalination process refers to the loss or leaching of soil salt, and refers to the loss of soluble salt in soil due to natural or artificial conditions. Precipitation, surface water infiltration and groundwater level decline in the natural environment will cause the dissolution and loss of salt contained in the soil, which will gradually reduce the salt content of the soil. This is natural desalination. A very long natural desalting process can even reduce the soluble salt content in the soil to zero. [1]

When people improve the soil, they can use a certain amount of qualified water to irrigate the soil, which can accelerate the process of soil desalination and make the soil lose excess salt. In the process of artificial desalting of saline alkali soil, supporting drainage measures and other soil improvement technologies (such as well irrigation, well drainage, construction of terraces to reduce the groundwater level) must be provided, otherwise secondary salinization 。 Desalination process can change saline soil into non saline collapsible soil.
