Aspect Measured Likelihood of a Salinity-Related Problem Occurring*
None Slight to Moderate High
ECe 0.5–2.0 dS/m 2.0–4.0 dS/m > 4.0 dS/m
SAR SAR < 6 SAR of 6–9 SAR > 9
sodium --- > 230 mg/l ---
chloride < 100 mg/l 100–200 mg/l > 250 mg/l
boron 0.1–0.5 mg/l 1–5 mg/l > 5 mg/l

* The actual likelihood of a problem occurring varies, depending on the tolerance of plants to salinity, and on the climate, and on the methods used to manage the soil and the irrigation water.
