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.
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.
The rows formed slow surface water run-off during rainstorms to prevent soil erosion and allow the water time to infiltrate into the soil. Soil conservation is the prevention of loss of the topmost layer of the soil from erosion or prevention of reduced fertility caused by over usage, acidification, salinization or other chemical soil contamination
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.
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.
