kasvualustakerros
Kasvualustakerros, often translated as growth medium layer or substrate layer, refers to a distinct horizontal stratum within a soil profile or a constructed growing system. In natural soil, it is a layer that supports plant life, providing essential nutrients, water, and anchorage for roots. This layer is typically characterized by its organic matter content, porosity, and microbial activity, which are crucial for plant development. The depth and composition of the kasvualustakerros can vary significantly depending on factors such as climate, parent material, topography, and time.
In horticultural and agricultural contexts, the term kasvualustakerros is also used to describe the engineered material
