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. The University of Wyoming and the Government of Alberta … Ver mais 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 Ver mais 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 to have very poor structure which limits or prevents water infiltration and … Ver mais Salinity from irrigation can occur over time wherever irrigation occurs, since almost all water (even natural rainfall) contains some dissolved salts. When the plants use the water, the salts are … Ver mais • Water portal • Alkali soil – Soil type with pH > 8.5 • Arabidopsis thaliana responses to salinity • Biosaline agriculture – Production of crops in salt-rich conditions Ver mais 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 out of the soil by drainage water in … Ver mais 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 … Ver mais 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, … Ver mais WebCreated by Mjdm Terms in this set (11) hectare (ha) unit of measure equal to 2.5 acres or 10,000 square meters land degradation reduced ability of the soil to support life …

WebFor all treatments we studied, keeping soil salt content in the range of 2~3 g/kg and soil water content in the range of 70%~85% of the field water capacity was optimal to improve resistance of the crop to both salinity and water stresses. Key words: water salt stress; alfalfa; biomass; osmotic regulating substance; antioxidant enzyme activity Webto or higher than those of similar non- saline soils. The abnormally high salt concentration of the soil solution of saline soils, however, reduces the rate at which plants absorb water; conse-quently growth is retarded.

Salt-affected soils (SAS) describe both saline soils and sodic soils.Saline soils contain salts more soluble than gypsum in a concentration sufficient to negatively affect the ability of plants to take up water, while sodic soils contain high amounts of sodium ions that weaken the bond between the soil particles adversely … WebHigh soluble salt levels in the soil can cause plant drought stress. Water in the soil is drawn away from tender plant roots to the nearby high soluble salt areas in the soil. … china chef cary nc
