Assessment and Characterization of Agricultural Salt-Affected Soils around Abaya and Chamo Lakes, South Ethiopia Rift Valley

Table 2

Guideline for classification of salt-affected soils.

Classification	EC of saturation extracts (ECe) at 25°C (mmhos/cm)	Exchangeable Na percentage (ESP)	pH (H2O)	Soil physical condition
Saline	>4	<15	<8.5	Normal
Sodic (alkali)	<4	>15	>8.5	Very poor
Saline sodic	>4	>15	<8.5	Normal
Non-saline non-sodic	<4	<15	≈7.0	Normal
