SEASONAL pH FLUCTUATIONS IN A GREY WOODED SOIL

Abstract
Seasonal fluctuations in pH values were determined on soil samples from a modal Grey Wooded soil (Cooking Lake series). Samples were collected from the A0, A2, and B1 horizons at regular intervals from May to November. During this period the pH of each horizon varied from neutral to strongly acid. These fluctuations appeared to be related to the soil moisture and possibly to the soil temperature regime.
