Soil quality. Parameters for geochemical modelling of leaching and speciation of constituents in soils and materials - Extraction of humic substances from solid samples Ingestion-build-183511 lignite tar1 Scope This part of ISO 12782 specifies a procedure to determine the concentration of humic substances in soil or other materials. Other materials also include waste. The content of humic substances can be used as input in geochemical models.
