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]
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.
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.
Dryland salinity is a natural process for soil, just like other processes such as wind erosion. Salinity degrades land by an increase in soil salt concentration in the environment, watercourse or soil in unirrigated landscapes, being in excess of normal soil salt concentrations in dryland regions.
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.
Freshwater salinization can negatively effect the species richness, diversity, and community composition across multiple trophic levels. Competitive interactions between zooplankton can change as salinity increases, leading species such as Simocephalus vetulus to outcompete the normally-dominant Daphnia galeata under high salinity treatments.

The first global map of oceanic surface salinity, produced by the SMOS satellite. The salinity varies from 32‰ (deep purple) to 38‰ (bright red). Soil moisture is an important aspect of climate, and therefore forecasting. Plants transpire water from depths lower than 1 meter in many places and satellites like SMOS can only provide moisture ...
Salinization is the process of increasing: Soil salinity; Salinity of bodies of water; Freshwater salinization-- increases in water salinity due to water pollution
