Question

3 different classes of soil salinity and tge criteria of classification

Answer 1

Soil salinity is the salt content in the soil; the process of increasing the salt content is known as salinization.[1] 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 processes such as irrigation and road salt.

Soil Salinity ClassConductivity of the Saturation Extract (dS/m)
1.Slightly saline2 - 4

2.Moderately saline4 - 8

3.Strongly saline8 - 16

4.Very strongly saline> 16
