Previously reported methods for determination of exchangeable calcium in soil, involving extraction with solutions of sodium, potassium or ammonium chloride or shaking with a carbonate solution, are critically reviewed and their sources of error discussed. A new procedure is recommended in which the exchangeable calcium is extracted with a O‐2N‐KC1 solution previously brought into equilibrium with solid calcium carbonate.
