This study was to investigate the chemical characteristics of soils in Cheju [Korea R.] island. Cheju citrus orchards have been chemically fertilized with both phosphates high in Ca and Mg contents and potassium. Available phosphorus of sub-soil increased slightly with the number of years under cultivation compared to that of surface soil. Base saturation and pH increased with the number of years under cultivation, inasmuch as exchangeable bases such as Ca, Mg and K increased predominantly, but the cation exchange capacity did not vary in the citrus orchard soils
