Soil salinity is the salt content in the soil; the process of increasing the salt content is known as salinization. Salts occur naturally within soils and water. Salination can be caused by natural processes such as mineral weathering or by the gradual withdrawal of an ocean. It can also come about through artificial processes … See more Salts are a natural component in soils and water. The ions responsible for salination are: Na , K , Ca , Mg and Cl . Over long periods of time, as soil minerals weather and release salts, these salts are flushed or leached … See more Salinity in drylands can occur when the water table is between two and three metres from the surface of the soil. The salts from the groundwater are raised by capillary action to the surface of the soil. This occurs when groundwater is saline (which is true in … See more The consequences of salinity are • Detrimental effects on plant growth and yield • Damage to infrastructure (roads, bricks, corrosion of pipes and cables) • Reduction of water quality for users, sedimentation problems, increased leaching of metals, … See more When the Na (sodium) predominates, soils can become sodic. The pH of sodic soils may be acidic, neutral or alkaline. Sodic soils present particular challenges because they tend … See more Salinity from irrigation can occur over time wherever irrigation occurs, since almost all water (even natural rainfall) contains some dissolved salts.
