International Humic Substances Society
From Wikipedia, the free encyclopedia
The International Humic Substances Society is a scientific society with a focus on research into natural organic matter (NOM) in soil and water.[1]
The International Humic Substances Society was founded in Denver, Colorado, USA, on September 11, 1981 by scientists who saw a need for a society to bring together scientists in the coal, soil, and water with interest in humic substances, and to provide opportunities for them to exchange ideas .[2][3] As of 2023, the society has about 450 members in 24 country and regional chapters.
Standard and reference sample collection
The International Humic Substances Society maintains a collection of standard and reference samples of humic and fulvic acids extracted and fractionated from leonardite, river water, a mineral soil, and peat, plus natural organic matter isolated from river water by reverse osmosis,[4] without fractionation.[5] These standards, which represent an important fraction of soil and water[6] are sold to scientists around the world for use as standards in environmental and agricultural research, and have been used by scientists in approximately 40 countries for a wide variety studies.[7][8][9][10][11]
