This study examines the spatial distribution patterns and morphological characteristics of Macrotermes falciger mounds in the peri-urban zone of Lubumbashi, D.R. Congo. Spatial patterns of mounds were assessed using high-resolution satellite images for 24 plots of variable size (3 to 27ha). Soil morphological features were described for five termite-mound profiles of 5 to 9m depth/height. A mean areal...
The influence of Macrotermes falciger activity on clays, sesquioxides and water-dispersible clay (WDC) content was investigated by a physico-chemical, mineralogical and micromorphological study of termite mound and control soil profiles at various sites near Lubumbashi, SE Katanga, D.R. Congo. X-ray diffraction reveals that the termite-mound materials are enriched in 2:1 clays, especially mica and...
Maintenance of soil quality is critical to environmental sustainability. However, its input cost is becoming unaffordable to small scale farming communities in Africa. Termites are an important element in traditional land-management practices in the Sahel. In their role as regulators of soil ecosystem processes, termites perform a number of vital functions. Although the application of termite mound...
The origin of carbonate accumulations in termite mounds is a controversial issue. This study is an attempt to elucidate the processes of carbonate precipitation in Macrotermes mounds built on Ferralsols in Upper Katanga, D.R. Congo, whereby a differentiation between pedogenic and inherited carbonates is considered. Carbonate features were investigated for a 9m deep termite-mound profile, and for an...
