Abstract
Termite mounds and adjacent soils were sampled in three rainfall zones: < 700 mm, 700–1000 mm and > 1000 mm per annum. Electrical conductivity, and extractable calcium, magnesium and potassium are significantly higher in termite mounds than adjacent soils in all rainfall zones. Values of pH, electrical conductivity and extractable calcium show large differences between termite mounds and adjacent soils in the low- and medium-rainfall zones, and small differences in the high-rainfall zone. Differences in the absolute concentration of extractable calcium (extract. Ca mounds - extract. Ca soils) between termite mounds of the three rainfall zones were probably caused mainly by leaching.
