The pH of these soils range from 4.0 to 4.5, values too acidic for the cultivation of most common cereal grains and root crops in Zambia (maize, finger millet, sorghum, and cassava). The chitemene system, which creates a surplus of ash in concentrated spaces, raises the soil pH , enabling the cultivation of those crops.
