Management of Salt-Affected Soils: A Photographic Mini-Review

Abstract

Soil is the main source of human food, feeds for our animal, fiber, and a major source of fuel. The ability of soil to supply life essentials can be impacted by several obstacles that reduce or prevent plant production. Salt-affected soils are common under arid and semi-arid climates, which often produce soils that have salinity and/or alkalinity problems. Salinity and alkalinity are of important stresses mainly include oxidative and osmotic stress, which threaten the crop productivity under such soil conditions with distinguished decline. Successful production in such soils needs a deep understanding of their formation and productivity challenges. Due to the increase areas of salt-affected soils in the world, the management of these soils is a crucial global issue. This paper is a mini-review on salt-affected soils, which include their characterization and suitable management approaches. Nano-management of salt-affected soils as a promising approach will also be discussed and new perspectives and challenges in remediation of salt-affected soils will be highlighted.
