Genesis, Properties and Management of Salt-Affected Soils in the Flooding Pampas, Argentina
The Flooding Pampa is a plain, covering around 90,000 km2 composed of eolian and alluvial deposits. It is characterized by its geomorphology, with low (0.1–0.01%) slopes and elevations, including the coastal flat. A significant fraction of the region has

Foreword
As world population continues to expand, global need for increased food production is pushing agriculture into regions with lower rainfall and salt-affected soils. This increases the pressure to develop and extend irrigation schemes and to bring marginal land into production. Soil salinization is becoming more extensive as a result of land clearing and unsustainable irrigation practices, and is a major cause of land degradation. The need for more food means more dependence on irrigation schemes which typically result in 25–50% of the irrigated land being salinized. Clearing of natural vegetation for cropping or grazing brings salt to the surface. Low-lyi
