Humic Substances.: Elham A. Ghabbour, G. Davies, Geoffrey Davies, Royal Society of Chemistry Great Britain Royal Society of Chemistry, 2001 - Science - 387 pages. 1 Review. Humic substances. Humic substances, the remarkable brown biomaterials in animals, coals, plants, sediments, soils and waters, are crucial components of the carbon cycle and other life processes. Thus greater knowledge and understanding of these versatile materials is of great importance to the productivity, health and safety of the world's ecosystems, humans, land and water.

Waksman [] reviewed publications on the origin, composition and importance of humic materials.Humus is Latin for soil, and humic substances HS are natural organic compounds which are sourced from plants, peat, soil and coals such as lignite and leonardite. Note that leonardite actually refers to a particular geological deposit of oxidised lignite in North Dakota, but is often misapplied to.

May 22, 2019 · Humic substances are able to form stable complexes with metal micronutrients, due to the presence in their structure of oxygen-, nitrogen- and sulfur-containing functional groups. This, in turn, would help maintaining micronutrients in solution and/or in bioavailable forms at pH values found in most soils Senesi, 1992; Tipping, 2002.

A critical examination of published data obtained primarily from recent nuclear magnetic resonance spectroscopy, X-ray absorption near-edge structure spectroscopy, electrospray ionization−mass spectrometry, and pyrolysis studies reveals an evolving new view of the molecular structure of soil humic substances. According to the new view, humic substances are collections of diverse,. Humic substances are complex, heterogeneous, mixtures of organic compounds with different functional groups, and their molecular masses MM are still operationally defined and being debated 1,2,3,4.Humic substances can be operationally defined into fulvic acid FA; soluble at all pH values, humic acid HA; soluble in alkaline media and insoluble at pH 1.0, and humin insoluble at all pH.

It is used to condition soils either by applying it directly to the land, or by providing a source of humic acid or potassium. Jan 01, 2015 · Studies often show reversal of deadly cancers and tumors using special humic substance therapies [47]. On the other hand, humic acid has been shown to be a toxic factor for many mammalian cells, but the specific mechanism of its cytotoxicity remains unclear. Davies, G., E.A. Ghabbour and C.
