Comparing to the same non-salinized soil, what happens to a salinized soil regarding its porosity and retention capacity?
Any papers as reference would help.
Dear Barbara,
salinity can affect soil physical properties by causing fine particles to bind together into aggregates. This process is known as 'flocculation' and is beneficial in terms of soil aeration, root penetration, and root growth. Although salinity has a positive effect on soil aggregation, stabilization and water retention, at high levels salinity can have negative and potentially lethal effects on plants. As a result, salinity cannot be increased to maintain soil structure without considering potential impacts on plant health.
When the soil pH is greater than 8.5 ,the soil cations such as Ca ,Na , Mg will be present in soils at higher concentrations[ saline and sodic soil condition] ,therefore, Na will disperse the soil separates such as sand, silt , clay components leading to loose soil components and this will affect other physical properties such as soil structure .temperature .aeration ,water retention and also affects soil microbes The salt content of irrigation water must be determined to avoid soil salinity and destruction of soil equilbrium as well as wilting of crops
