WebJun 26, 2024 · Total Exchangeable Capacity and Exchangeable Bases Total exchangeable capacity (TEC) varies between 3.80 and 35.4, 2.08 and 35.08, 4.72 and 12.77, 3.53 and 26.54, and 2.46 and 5.12 meq/100 g for soil samples in the Far North, North, Centre, Adamawa, and the West regions, respectively (Tables 2 – 6 ). Webtotal potential acidity of the soils varied from 29.43-61.32 cmol(p +)/kg. It was apparent that the total potential acidity in most of the soils, decreased with the depth of soils (Figure 1). This might be due to the deposition of exchangeable bases with increasing soil depth. The higher values of the total potential acidity
