Silvertooth: Table 1, General classification of salt- and sodium-affected soils

 

Criterion

 Soil type
Normal Saline Sodic Saline-sodic
ECe(dS m-1) <4 >4 <4 >4
SARe <13 <13 >13 >13

ECe = the tolerance level for the specific crop or plant species in question, expressed as the electrical conductivity (EC) in deciSiemens per meter (dS m-1) of the saturated paste extract of the soil
SARe = the sodium adsorption ratio of the saturated paste extract of the soil
