Abstract

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.

## Abstract The organic phosphorus content of 33 calcareous soils (0.1‐52.4% CaCO^3^,) was determined by the ignition method and by hydrogen peroxide oxidation. Mean values for organic phosphorus expressed as a percentage of the total phosphorus were 14.5% and 15.6% for the two methods respectively
