Maaperänkin

Maaperänkin is a term used in Finnish to describe a layer or stratum within the soil. It refers to distinct horizontal or near-horizontal divisions of soil that differ in characteristics such as texture, color, structure, and mineral content from the layers above and below. These layers, collectively known as soil horizons, are formed through various soil-forming processes over time. The uppermost layer, the topsoil or A horizon, is typically rich in organic matter and is crucial for plant growth. Beneath this lies the subsoil, or B horizon, which often accumulates minerals leached from the layer above. Deeper still is the parent material, the C horizon, which is partially weathered rock. The characteristics of each maaperänkin are influenced by factors like climate, parent material, topography, organisms, and time. Studying these layers helps in understanding soil properties, fertility, drainage, and its suitability for different land uses.
