Photographer's Note

O processo de formação do húmus é chamado humificação, e pode ser natural, quando produzido espontâneamente por bactérias e fungos do solo; agentes como chuva, água e temperatura contribuem para a humificação.

HUMUS, organic matter that has decayed to a relatively stable, amorphous state. Humus is formed by the decomposing action of soil microorganisms (e.g., bacteria and fungi), which break down animal and vegetable material into elements that can be used by growing plants. Because of its low specific weight and high surface area, humus has a profound effect upon the physical properties of mineral soils with regard to improved soil structure.
