Kéregrétegek

Kéregrétegek refers to layered geological formations found in certain soil types, particularly those developed under specific climatic and vegetational conditions. These layers are typically distinguishable by variations in color, texture, and composition, often resulting from distinct processes of soil formation over time. The term is Hungarian and literally translates to "loam layers" or "mulch layers," hinting at the organic matter content and the stratified nature of these soils.

These formations are often associated with the development of Chernozem soils, also known as black earths, which are highly fertile and rich in humus. The distinct layers within a kéregredetek profile reflect the accumulation and decomposition of organic matter, mineral weathering, and the movement of water and dissolved substances through the soil profile. For instance, a darker, organic-rich top layer might transition to a lighter-colored, mineral-rich layer below, with further variations depending on the parent material and the age of the soil.

Understanding the structure of kéregretek is crucial for agricultural applications, as it indicates the soil's fertility, water-holding capacity, and drainage characteristics. Soil scientists analyze these layers to assess soil health and predict crop yields. The presence and distinctness of these layers can also be influenced by factors such as tillage practices, land use history, and the presence of specific biological activity within the soil.
