Dr. Richard T. Lamar and Dr. Hiarhi Monda of our Humic Research Laboratory, with assistance from analytical chemist Ryan Fountain, have published a methodology video in the biochemistry section of the peer-reviewed online video journal, JoVE.
The video, Quantification of Humic and Fulvic Acids in Humate Ores, DOC, Humified Materials and Humic Substance-Containing Commercial Products, shows the step-by-step laboratory methodology (the New Standard Method) for gravimetric quantification of humic substances (e.g., humic and fulvic acids) on an ash-free basis, in dry and liquid materials from soft coals (i.e., oxidized and non-oxidized lignite and sub-bituminous coal), humate ores and shales, peats, composts and commercial fertilizers and soil amendments.
In the video introduction, Dr. Lamar states, “The New Standard Method for quantification of humic acids provides a more accurate and precise analysis compared to the existing regulatorily accepted methods, and it also provides a standard method for pure hydrophobic fulvic acid quantification. The advantage of this protocol is that it provides a gravimetric analysis of humic and hydrophobic fulvic acid concentrations on an ash-free basis, and the extraction process has been optimized to obtain the highest recoveries of both humic and fulvic acids from samples.
At the video’s conclusion, Dr. Monda states, “Following this procedure, the dry humic and fulvic acids obtained can be used for characterization purposes, such as the carbon-13 and the proton NMR electron resonance, and the ultrahigh resolution mass spectrometry, among other useful techniques. This can be used for characterization of the humus chemistry, as well as being a useful tool to dig deep into the structure-activity relationship with plant fitness and the underlying plant defense mechanisms.
