There are basically three potential hazards of salt-degraded soils to plants—salinity, sodicity, and alkalinity. The first two hazards are used to classify soils as saline or sodic, or both, as described in Table 8.4. The alkalinity hazard (measured by RSC) is not usually applied directly to the classification of soils, but the pH values reported in Table 8.4 indicate that sodic soils are the most likely to have a problem of high alkaUnity. This arises partly from the hydrolytic exchange reaction, described in Chapter 3, which is enabled by the presence of appreciable exchangeable Na" and low salt concentrations, conditions that are diagnostic of sodic soils. Hydrolytic exchange can be viewed as a two-step reaction ... 

The leaching of saline-sodic soil with good water (low salinity, low SAR) causes the pH to rise. This can result in the mobilization of trace elements such as selenium in some soils (selenium exists in the soil as an oxyanion, selenite or selenate), elements that adsorb better at low pH than high pH. How would you prevent this potential environmental risk to groundwater during the reclamation of the saline-sodic soil ...

Soils are said to be sodic if they contain an excess of sodium. According to their content of salts and sodium, soils are grouped in saline-nonsodic, saline-sodic, nonsaline-sodic, and normal soils. In arid regions, soils rich in sodium are widely distributed due to salt accumulation as sodium chloride and sodium sulfate. The salt-affected soils are chemically characterized by the specific conductivity (mS-cm ) [S = Siemens] of the saturation extract and the saturation of the CEC (%) with sodium. The major cationic constituents of the soluble salts in saline soils are sodium, calcium, and magnesium. Precipitation of Ca and Mg as carbonates effects an increase in the proportion...
