A comparison of 5 methods for the determination of cation‐exchange capacity of soils of the Lower Coastal Plain was made on surface and subsoil samples of 4 soil series. The methods employed were: ( 1 ) direct distillation of NH 4 + ‐saturated soils, ( 2 ) distillation of ammonia from NaCl extract, ( 3 ) barium chloride‐triethanolamine, ( 4 ) calcium acetate‐barium hydroxide, and ( 5 ) calcium acetateflame. On the average, method 3 gave results intermediate between those obtained by methods 1 and 2, method 4 gave low results and method 5 gave high results.
