摘要:

The CEC of various Spanish soils derived from volcanic ashes was determined by using different procedures: (1) displacement with 1N NaOAc, pH 8.2 (2) effective CEC determined as the total exchangeable bases displaced with NH4OAc plus exchangeable Al extracted with 1N KCl and (3) compulsive exchange of Mg for Ba.
