The amounts of potassium extracted from soil by electrodialysis and by ammonium acetate leaching have been compared for soils taken from long‐term manurial trials. More potash was extracted, from soils receiving potash treatment, by electrodialysis in a Marsden cell than by ammonium acetate leaching; the difference increased as the dressing increased. With untreated soils slightly more potash was removed by ammonium acetate leaching than by electrodialysis. The non‐exchangeable potassium removed from soil by electrodialysis is probably derived from added and subsequently fixed potassium rather than from primary potassium‐bearing minerals.
