As a result, jungle soil relies on the presence of humus, an organic substance produced by microbes that cause dead plants to decay; humus mimics the ability of clay minerals to retain soil moisture and nutrients. However, humus is much more fragile than clay minerals to chemical weathering, and is protected by the tall rainforest canopy, which softens the torrential rainfall
