When the salt concentration is too high, it means that the soils osmotic potential is essentially negative. All the possible sources of related and up to date literature have been . Soil salinization is most prevalent in arid and semi-arid climates because evaporation exceeds precipitation. Apart from visual changes, there are indirect indicators of extra salt concentration. It is most common in densely populated areas of the world where large-scale farming has been common for a long period of time. Thus, salinization reduces ecosystem varieties and threatens their normal conditions to exist.

Salinization reduces biodiversity in rivers or fresh-water lakes, shortening aquatic populations solely to salt-tolerant species. Because salts are water-soluble, they can enter into soil environments through groundwater, flooding, or irrigation.2 Salts may accumulate in soil for a variety of reasons, all of which relate to some disruption in water and water-soluble salt dynamics. Soil salinization is most common in arid climates, but it also occurs wherever irrigation is used. Similarly, mild slopes that create shallow pool areas for water accumulate salts as water is evaporated out. Satellites retrieve data with SWIR and NIR bands for remote sensing analytics of water absorption and its possible correlation with salinity.
