pH was measured by glass electrode in mull and mor woodland soils, and in a lake mud core. Direct electrode insertion yielded the lowest values, intermediate values were given by expressed soil solutions, and the highest pH levels were observed after aeration of soil solutions. These methods gave pH differences of up to 2.1 units on single samples.
