Biomassemengen

Biomassemengen refers to the quantities of biomass, the total mass of organic matter produced by living organisms, or available for use, within a given system. In ecological and agricultural contexts, it denotes the amount of biomass present or produced per area over time, and may be expressed as dry mass or carbon mass. Common units include tonnes or megatonnes, kilograms per square meter, or tonnes per hectare per year, with moisture content and dry matter fraction influencing conversions between units.

Measurement and estimation rely on field inventories, allometric equations, harvest data, and remote sensing. Biomass stock is often estimated using allometric relationships between measurable traits (such as tree diameter or height) and biomass, while productivity is derived from growth measurements, satellite data, and modeling.

Biomassemengen are used to assess energy potential, carbon storage, and the sustainability of land-use systems. In energy planning, biomass quantities are linked to bioenergy potential, with considerations of moisture, ash content, and calorific value. In ecology, they inform studies of ecosystem productivity, trophic dynamics, and habitat quality.

Challenges include spatial and temporal variability, uncertainties in allometric models, and differences between fresh and dry mass. Accurate accounting requires standard definitions of biomass type (aboveground, belowground, dead material) and consistent measurement protocols.
