WebSoil salinity in agriculture in a simpler and most correct definition is the high concentrations of salts in the soil profile. The process of salinization can occur either naturally or by anthropogenic activities. The high concentration of salts interrupts the plant’s metabolism making them unable to absorb water, nutrients, and microelements.

WebSodicity is a condition that degrades soil properties by making the soil more dispersible, restricting water entry and reducing hydraulic conductivity (the ability of the soil to conduct water). These factors limit leaching so that salt accumulates over long periods of time, giving rise to saline subsoils.
