jordprofill

Jordprofill is a term used in soil science to describe the vertical sequence of soil layers within a location, also known as a soil profile. It captures the arrangement and properties of horizons from the surface to the underlying parent material and forms the basis for soil classification, moisture assessment, and land-use planning.

A typical jordprofill includes horizons designated O, A, E, B, C and, where present, R. Descriptions cover color, texture, structure, organic matter content, pH, and moisture regime, as well as depth to each horizon boundary. Transitional horizons and mixed layers may occur.

Field methods include describing a pit or trench, augering, or coring to observe horizons; samples are collected for laboratory analysis (texture, chemistry, and bulk density). Classification follows established systems such as Soil Taxonomy or the World Reference Base for Soil Resources, with the profile used to assign a soil type and properties.

Applications include agricultural planning, forestry, watershed and environmental assessment, land management, drainage design, and construction suitability. Soil profiles also aid hydrological modeling by indicating root zones and water movement through horizons.

Terminology: while jordprofill is common in some Scandinavian languages as the equivalent of 'soil profile,' English-language literature typically uses the term 'soil profile.' The concept is widely used in education, research, and professional practice.
