Abstract
Abstract. The pH of soil samples was remeasured after storage for 20 years in the laboratory. The pH decreases were minor in acid to neutral soils (‐0.3), but greater in alkaline soils (‐0.63). The pH differences were statistically significant only for alkaline soils. The decreases of pH with time are probably mainly due to the decomposition of organic matter, the CO 2 produced, the hydroscopic water and the presence of CaCO 3 .
