 The manifestation of dryland salinity is largely a problem of groundwater – however the accumulation of salt within the soil and at the surface due to proximity to or saturation by saline groundwater causes changes to the soil’s chemistry, structure and stability, and the plant life that it supports.In discharge areas, salinity can be managed by establishing salt-tolerant plants or by engineering systems.Engineering systems include deep open drains, pumps, siphons and various forms of surface water management.
