Soil salinity is the salt content in the soil; the process of increasing the salt content is known as salinization. [1] Salts occur naturally within soils and water. Salination can be caused by natural processes such as mineral weathering or by the gradual withdrawal of an ocean.
where water tables are shallow, the irrigation applications are reduced. As a result, the soil is no longer leached and soil salinity problems develop; stagnant water tables at the soil surface are known to increase the incidence of water-borne diseases like malaria, filariasis, yellow fever, dengue, and schistosomiasis (Bilharzia) in many ...
The soil under most wetlands is relatively impermeable. A high perimeter to volume ratio, such as in small wetlands, means that the surface area through which water can infiltrate into the groundwater typical in small wetlands such as prairie potholes , which can contribute significantly to recharge of regional groundwater resources.

Soil salinity control refers to controlling the process and progress of soil salinity to prevent soil degradation by salination and reclamation of already salty (saline) soils. Soil reclamation is also known as soil improvement, rehabilitation, remediation , recuperation, or amelioration.
Biosaline agriculture is the production and growth of plants in saline rich groundwater and/or soil. [1] In water scarce locations, salinity poses a serious threat to agriculture due to its toxicity to most plants. [2] Abiotic stressors such as salinity, extreme temperatures, and drought make plant growth difficult in many climate regions. [2]
Salt-affected soils on rangeland in Colorado.. The U.S. Salinity Laboratory is a National Laboratory for research on salt-affected soil-plant-water systems. It resorts under the Agricultural Research Service (ARS) of the United States Department of Agriculture (USDA) and is located in Riverside, California, U.S.A.
UC Davis researchers say the soil in the Salton Sea air basin emits more than 11 tons per day of nitrogen oxides — about 10 times more smog-forming pollution than California air regulator ...
As salinity increases within a freshwater ecosystem, often this results in a decrease of biota diversity and richness. [19] The extinction rate for freshwater organisms are among the highest worldwide, [3] and as salinity levels in these aquatic ecosystems continue to increase, more species and their environments will become threatened.
