Question

which of the following soils is saline in character ?
a) Reguar b) Usar c) Kari d) Khadar​

Answer 1

Usar

Saline Soils are those soils that contain sufficient salinity to give ECe Values greater than 4 dS/m, but have an ESP less than 15 (or an SAR less than 13) in the saturation extract. Thus, exchange complex of saline soils is dominated by calcium and magnesium, not sodium. The pH of saline soils is usually below 8.5.
