Review of Reclamation of salinity affected soils by leaching and their effect on soil properties and plant growth

The irrigated soils in dry and semi-arid areas suffer from the problem of salt accumulation because not using sufficient leaching water to remove salts added with irrigation water. Soil salinity contributes a decrease growth productivity plants grown those conditions, as well affecting physical, chemical hydraulic properties soil. reclamation process is radical solution salinization, one most important basic ingredients for success saline determine optimal amount or what called ( Norm). Hence, net movement are required prevent them concentrating root zone appropriate level plants' tolerance ensure that it does affect their productivity. concept soil improving its physical depends on several factors, including method leaching, salinity, during time period other factors. present surface layer transfer depths there places puncture, they also indicated increase periods low intermittent showed greater efficiency less quantities water, addition may From speed soil, increasing contribute reducing studied especially unsaturated conditions.
