Incubation of phosphorus (P)‐treated soils for up to 240 days had no effect on the P‐induced cation exchange capacity (CEC) of subsoil samples of three volcanic ash‐derived soils of southern Chile. Washing one soil with large volumes of distilled water desorbed small quantities of P but had no effect on CEC.
