Extracted humic acid not a single acid; rather, it is a complex mixture of many different acids containing carboxyl and phenolate groups so that the mixture behaves functionally as a dibasic acid or, occasionally, as a tribasic acid. Commercial humic acid used to amend soil is manufactured using these same well established procedures.
Dystrophic lakes, also known as humic lakes, are lakes that contain high amounts of humic substances and organic acids. [1] The presence of these substances causes the water to be brown in colour and have a generally low pH of around 4.0-6.0. [ 2 ]
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]
The organic components can be subdivided into fractions that are soluble, largely humic acids, and insoluble, the humins. Humins make up about 50% of the organic matter in soil. Humins make up about 50% of the organic matter in soil.
These largely neutralized the decomposing properties of the humic acid of the fens in the former Geiseltal, but were, as can be seen from the finds, only locally effective. To a lesser extent, silicic acid also ensured good preservation of the fossils.
