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 … Visa mer 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 … Visa mer 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 … Visa mer 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, … Visa mer When the Na (sodium) predominates, soils can become sodic. The pH of sodic soils may be acidic, neutral or alkaline. Sodic soils present … Visa mer Salinity from irrigation can occur over time wherever irrigation occurs, since almost all water (even natural rainfall) contains some dissolved salts. … Visa mer High levels of soil salinity can be tolerated if salt-tolerant plants are grown. Sensitive crops lose their vigor already in slightly saline soils, most crops are negatively affected by (moderately) saline soils, and only salinity-resistant crops thrive in severely saline soils. … Visa mer • Water portal • Alkali soil – Soil type with pH > 8.5 • Arabidopsis thaliana responses to salinity • Biosaline agriculture – Production of crops in salt-rich conditions Visa mer business requirements for software
