SOILS and NUTRIENT CYCLING IN THE RAINFOREST
Understanding the basic composition of forest soils helps explain the concept of nutrient cycling in the rainforest; why there are problems with clearing rainforest lands for agriculture; and how soils are an important factor influencing forest complexity.
SOIL COMPOSITION
Over two-thirds of the world's rainforests -- including much of those in Madagascar -- can be considered "wet-deserts" in that they grow on extremely poor soils which are acidic and low in minerals and nutrients. The key to the luxuriant vegetation of these forests lies in the rapid nutrient cycling of the rainforest.
