Suitability Assessment of Surface Water Quality for Irrigation: A Case Study of Modjo River, Ethiopia

Table 3

Irrigation water salinity ratings based on electrical conductivity (Source: [20]).

EC (dS/m)	<0.65	0.65–1.3	1.3–2.9	2.9–5.2	5.2–8.1	>8.1
Water salinity rating	Very low	Low	Medium	High	Very high	Extreme
Plant suitability	Sensitive crops	Moderately sensitive crops	Moderately tolerant crops	Tolerant crops	Very tolerant crops	Generally too saline
