As a service to all scientists who are interested in humic substances, we have compiled a list of reference books dealing with humic substances in soils, sediments, and natural waters. We need input from readers to keep this list up-to-date.

If you know of a good book that should be on this list, please inform [ ]. Introduction to the International Humic Substances Society (IHSS). This website provides information on the International Humic Substance Society (IHSS), its products and services.

IHSS was founded in Denver, Colorado, USA, on Septem to bring together scientists in the coal, soil, and water sciences with interests in humic substances. The properties of humic substances (HSs) in plants, soils and sediments regulate the environment and affect all aspects of like, yet they are only very imprecisely understood.

This volume presents work on HSs including instruments and techniques being developed to throw more light on their structure and relationship to macro- and micro-scopic.

Based on the Second International Conference of the International Humic Substances Society held in Birmingham, England, inthis compendium reviews ways of studying the structure and function of humic substances, including the use of both degradative and nondegradative processes.

The use of coal-based humic substances for soil enhancement, water purification and soil remediation as an alternative to present methods is explored. Comprehensive, with contributions from international experts, "Humic Substances" will have a broad appeal to researchers in many disciplines, including agricultural and environmental science.4/5(1).

Humic acid is filled with trace minerals to help your body running smoothly. Alleviates the Common Cold. If you’re feeling sick, humic acid might just be the remedy you need. A study found that regular doses of humic acid and fulvic acid could help alleviate the symptoms of the common cold quickly and comfortably.

Fights Bronchitis. Properties of humic substances. Humic acids - the fraction of humic substances that is not soluble in water under acidic conditions (pH 2) but is soluble at higher pH can be extracted from soil by various reagents and which is insoluble in dilute acid.

The lack of such provided the inspiration for Humic Substances and Chemical Contaminants. The Soil Science Society of America (SSSA) and the International Humic Substances Society (IHSS) gave their willing support to a proposal for a Workshop and a Symposium on the subject matter at the annual meetings of the American Society of Agronomy, the.

Abstract. Humic substances in soils differ significantly from those in stream waters or ground waters. Soil humic substances are of higher molecular weight, of greater 14 C age, of greater percentage in aromatic C, of more intense color perC atom, and of higher polysaccharide content than their counterparts in streams and groundwaters.

Molecular Structure of Humic Substances. A focal point of this topic is to verify the existence of a relationship between structure and biological properties of HS. 29 So far the structure of HS is under debated. The main obstacle is the lack of a repetitive sequences and the variety of chemical and biological reactions involved in their genesis, 30 that make HS very Cited by: The International Humic Substances Society (IHSS) is a scientific society that seeks to advance knowledge and research of natural organic matter (NOM) in soil and water.

Humic substances are of interest because they are generally more chemically reactive with pesticides than are nonhumified materials (Farenhorst, ).
