Salt Tolerance of Plants: Strategies of Biological Systems

  • D. William Rains
Part of the Environmental Science Research book series (ESRH, volume 14)


Large terrestrial areas of the world are affected by levels of salt inimical to plant growth. It has been estimated that as many as 4 × 108hectares (ha) of the 1.5 × 109 ha land currently under cultivation have enough salt to reduce the agronomic potential of these areas (28). This is exclusive of the regions classified as arid lands (14). With the enormous amount of arid land, it is very possible that the hectares of land affected by elevated levels of salt will exceed 1.5 × 109 ha or approximately 40% of the 4 × 109 ha of potentially arable land.
