Why does humus form quickly?

Humus forms quickly due to the rapid decomposition of organic matter by microorganisms, such as bacteria and fungi, particularly in warm and moist environments. This process is accelerated by the presence of diverse plant materials, which provide a rich source of nutrients. Additionally, the physical and chemical properties of the soil facilitate the retention of organic matter, allowing it to break down and transform into humus more efficiently. Overall, the right conditions and abundant microbial activity contribute to the swift formation of humus.
