Soil salinity can restrict plant growth and reduce crop yields. The high salt concentration in a saline seep prevents the uptake of water and essential nutrients by plant roots. Various measures are used to control and reduce the flow of groundwater that leads to dryland saline seep formation. This fact sheet provides an overview of saline seep formation and how to recognize it, discusses salinity classification, and briefly identifies the main methods of controlling soil salinity.
Plant species vary in how well they tolerate salt-affected soils. Some plants will tolerate high levels of salinity while others can tolerate little or no salinity. This brief fact sheet looks at how soil salinity is measured and categorized, and then presents a table delineating the salt tolerance of various types of plants, including field crops, forages, vegetables, and trees and shrubs.
