Saline Soil is characterized by

 > 2,600 ppm Soluble salts or an  EC 4mmhos/cm

Sodic or Alkali Soil is characterized by
> 15% of the cation exchanges sites occupied by Na.

1mmhos/cm = 1mS
1dS=100mS=100000ÁS

Saline Soils of the World

Salt-affected lands are reflected as saline seeps in dryland agriculture and secondarily salinized irrigated lands (Tanji 1995). Table 2 shows that globally more than 77 million ha of land is salt-affected by human-induced salinization (Oldeman et al. 1991). The authors have not distinguished between the extent of salt-affected land in irrigated and non-irrigated areas.
