leeflaag

Leeflaag is a term originating from Dutch that translates to "living layer" or "life layer." It generally refers to the uppermost layer of soil or sediment that is actively inhabited by organisms and plays a crucial role in ecological processes. This layer is characterized by its biological activity, including the presence of microorganisms, fungi, insects, worms, and plant roots. The leeflaag is where decomposition of organic matter occurs, nutrients are cycled, and essential soil structure is maintained.

The thickness of the leeflaag can vary significantly depending on the environment, ranging from a few centimeters in arid regions to over a meter in some mature forests. Factors such as moisture, temperature, and the availability of organic material influence its depth and composition. Healthy leeflaag is vital for plant growth, water infiltration, and the overall health of an ecosystem. Its degradation can lead to reduced fertility, increased erosion, and a decline in biodiversity. Conservation efforts often focus on protecting and restoring the leeflaag to ensure the long-term sustainability of natural and agricultural landscapes.
