Pdf Salt Affected Soils Saline Sodic Saline Sodic Soils And There are three types of salt affected soils: saline, sodic and saline sodic. these are classified based on their salinity (total salt content) and sodicity (the proportion of sodium). Saline sodic soils are characterized by ec e > 4 ds m −1 and esp > 15 (both salts and exchangeable sodium are high). these soils mainly occur in arid and semi arid regions where precipitation to evapotranspiration ratio is low.
Saline And Sodic Soils Ppt Sodic soil or soil sodicity may refer to: saline soil (sodic), a soil with excess salts where sodium chloride (nacl) predominates, and alkaline soil (sodic), a soil with a high ph (>8.5) due to the presence of excessive sodium carbonate (na 2 co 3). Excess salts in the ground pose a far reaching and expanding threat to agriculture across the globe. this publication discusses how salinity affects plant growth, yield, and soil structure. We evaluated the efficiency of gypsum, farmyard manure (fym) and cultural practices on the yield and yield components of wheat grown in saline sodic soil during rabi 2003 04. Even though closely related and having many characteristics in common, soil salinity and sodicity are two different problems, which should be dealt with differently and require slightly different management practices.

Table 1 summarizes the categories: saline, sodic, and saline sodic. understanding the differ ences is critical because these factors determine how the soils should be managed and reclaimed. Management of land, water, and plants to reduce the accumulation impacts of salts, sodium, or combination of salts and sodium on the soil surface and in the rooting zone. Soils may be affected only by salinity or by sodium or by a combination of both salinity and sodium. thus, soils can either be classified as saline, sodic, or saline sodic. To effectively manage soil salinity and sodicity, it is important to know the ec and sar of both the soil and the irrigation water. it is also important to know the grown crop’s salt tolerance.
