Scope

Specify a method for the determination of potential cation exchange capacity (CEC) and the content of exchangeable cations (Ca, K, Mg, Na) in soils using a molar ammonium acetate solution buffered at pH 7 as extractant.

Purpose

This method is already largely used all over the world. It is a very useful method well suited for agronomic interpretation. This standard will permit to harmonize the different practices.
