Lévymätan

Lévymätan is a Finnish term that translates to "leaf mold" or "leaf litter." It refers to the layer of dead, decaying leaves that accumulate on the forest floor. This organic material is a crucial component of forest ecosystems, playing a vital role in nutrient cycling and soil health.

The decomposition of leaf litter is primarily carried out by a diverse community of microorganisms, including bacteria and fungi, as well as invertebrates such as earthworms, mites, and springtails. As these organisms break down the leaves, they release essential nutrients like nitrogen, phosphorus, and carbon back into the soil, making them available for uptake by living plants.

Beyond its role in nutrient cycling, leaf litter provides insulation for the soil, protecting plant roots from extreme temperatures and helping to retain moisture. It also serves as habitat and food for a wide array of forest organisms, contributing to biodiversity. In Finnish culture and understanding of nature, lévymätan is recognized as a fundamental element that sustains the health and vitality of forested landscapes.
