Soil quality — Determination of effective cation exchange capacity and base saturation level using barium chloride solution
土壤质量 - 使用氯化钡溶液测定有效阳离子交换容量和碱饱和度
This document specifies a method for the determination of the cation exchange capacity (CEC) at the pH of the soil and for the determination of the content of exchangeable sodium, potassium, calcium and magnesium in soil.
This document is applicable to all types of air-dried soil samples. ISO 11464 can be used for pre-treatment.
