Abstract
Twenty-nine soil samples were selected within a field for similar pH (4.60–4.72) but with widely varying organic matter contents (3.5–20.5%). Exchangeable Al decreased while pH-dependent acidity increased with increasing organic matter content. The implication of these relationships for liming practices is discussed.Keywords
