jordlag
Jordlag is a term sometimes used in geology and soil science to refer to a distinct layer or horizon within the Earth's soil profile. It represents a recognizable zone with specific physical, chemical, and biological characteristics that differentiate it from the layers above and below. These characteristics can include variations in color, texture, structure, organic matter content, and mineral composition. The formation of distinct jordlag occurs over time through processes such as weathering of parent material, accumulation of organic matter, leaching of minerals, and biological activity. Understanding jordlag is crucial for agricultural practices, environmental assessments, and comprehending soil development. Different types of jordlag are identified and classified based on their properties and position within the soil profile. The study of these layers helps in understanding the history and dynamics of a particular soil.
