Talajprofilban

Talajprofilban is a term used in pedology to describe observations and descriptions that are made within a soil profile, the vertical sequence of soil horizons from the surface downward. A talajprofilban is used to capture the arrangement and development of horizons such as O, A, E, B, C and R, along with their boundaries, thicknesses and key properties. This framing helps in understanding soil formation processes, drainage, fertility, and the degree of weathering and eluviation or illuviation that characterize a site.

In a typical talajprofilban, the uppermost horizon is often organic-rich (O), followed by mineral horizons such as A and, if present, E, where leaching has partly removed soluble materials. Below them lie the B horizon, where materials have accumulated, and deeper C horizons representing less weathered parent material, with the R layer indicating bedrock. Each horizon is described by color, texture, structure, porosity, field moisture, pH and other diagnostic features. The depth to horizon boundaries and the presence of transition horizons (for example AB or BC) are also recorded.

Field methods for building a talajprofilban include digging a pit to observe in situ horizon boundaries, measuring depths, and recording color (often with a standardized chart), texture by feel, and structure. Samples may be collected for lab analyses of organic carbon, density, texture, and chemical properties. The talajprofilban provides essential input for soil classification, land-use planning, drainage assessment, and agricultural management, as horizon characteristics reflect fertility limitations, drainage status, and soil-forming history.

In Hungarian soil science, talajprofilban descriptions align with broader pedological practices used in soil surveys and ecosystem studies, and are often integrated with international soil classification frameworks to interpret soils across landscapes.
