Mullastikuelementide

Mullastikuelementide is a term used in Estonian soil science to denote the elements of the mullastik, or soil matrix. It describes the components that together determine soil behavior, fertility, and structure. The concept emphasizes that soil properties arise from the interaction of its parts rather than from any single component.

The elements typically include the mineral fraction (sand, silt, and clay and their mineral surfaces), organic matter (humus and other decomposed material), and the pore spaces filled with water and air. It also encompasses the physical structure or aggregation of soil, the living components such as roots, microorganisms, and soil fauna, and the chemical properties, including pH, cation exchange capacity, and available nutrients. Collectively these elements govern water retention and movement, aeration, nutrient availability, and biological activity within the soil.

Understanding mullastikuelementide supports practical work in soil science and land management. It informs soil surveys, fertility planning, erosion control, drainage decisions, and the effect of management practices like tillage or organic amendments on soil quality. The term is commonly used to frame discussions around texture, structure, maturity, and the integrated functioning of soils in various environments.

In summary, mullastikuelementide refers to the integrated set of components that compose the soil matrix and determine its physical, chemical, and biological behavior. See also pedology, soil texture, soil structure, and soil organic matter.
