The measured value of acid‐titratable basicity (ATB) or “alkaline earth carbonate from acid neutralization” decreases with increasing soil/solution ratio or the increasing concentration, C, of excess acid. The ATB is almost independent of C, however, in the range of 0.1 to 0.3 N acid remaining after neutralization with 0.5 N HCl. In coarse‐textured soils, the ATB extrapolated to C = 0 is reasonably close to the soil's carbonate content.
