Classification of salt affected soils

Classification of salt affected soils
       
  • Indian system of classification: Classified in to 2 major types of salt affected soils based on pH, EC and ESP.
    • Soil Characteristics

    Saline soils

    Alkali soils

    pH(s)

    8.2

    8.2

    ESP

    15

    15

    EC(e)

    4 ds/m

    Variable, mostly <4dS/m

    Nature of Soluble salts

    Neutral mostly Cl- & SO42-, HCO3- may be present but CO32- is absent
    Capable of alkaline hydrolysis, preponderance of HCO3- & CO32- of Na+.
