Humic component on a palm hand. This scrap of OH horizon is mostly composed of minute animal (arthropod and enchytraeid) droppings. It also corresponds to a sample of zoogenically transformed material. Non-zoogenically transformed material. Dry or cold climate, acidity, unpalatibility of the substrate, introduction of new and unadapted species (here the case of an organic topsoil in an artificial stand of Pinus radiata in substitution of a natural Quercus ilex forest) lags behind the arrival of pedofauna. The decomposition of the organic substrate is essentially due to fungal attack.
