适用范围：This International Standard specifies a method forthe determination of the cation exchange capacity(CEC) at the pH of the soil and of the determinationof the content of exchangeable sodium, potassium,calcium and magnesium in soil.This International Standard is applicable to alltypes of air-dried soil samples; pretreatmentaccording to ISO 11464 is recommended.NOTE 1 The method described suffers from interference fromcalcium as calcite or gypsum in the sample. Also, the presence ofany soluble salts gives values for the exchangeable cations thatare higher than the actual exchangeable amounts [3], [4].NOTE 2 Measurement of the specific electrical conductivity ofthe soil samples according to ISO 11265 will indicate if the soilsamples are affected by salt.
