Belüftungsschichten

Belüftungsschichten, also known as ventilation layers or aerated layers, are a concept primarily used in horticulture and agriculture to improve soil structure and aeration for plant roots. These layers are typically created by incorporating porous materials into the soil. The purpose of these layers is to prevent soil compaction, which can restrict oxygen availability to plant roots, hindering their growth and health.

The creation of belüftungsschichten often involves mixing organic matter such as compost, perlite, vermiculite, or coarse sand into the existing soil. These materials create small voids or pore spaces within the soil matrix. When water drains through the soil, these pores allow for the passage of air, ensuring a continuous supply of oxygen to the root zone. This improved aeration also facilitates the movement of water and nutrients.

In practice, belüftungsschichten can be incorporated during initial soil preparation or added as a top dressing. They are particularly beneficial in containers, raised beds, or in areas with heavy clay soils that are prone to waterlogging and compaction. The consistent availability of oxygen in the root zone promotes healthier root development, reduces the risk of root rot diseases, and ultimately leads to more vigorous plant growth and better yields. The specific materials and their proportions used to create belüftungsschichten can vary depending on the plant's requirements and the existing soil conditions.
