Description
Fulvic acids refer to collectively of a set of organic acids, natural compounds, and components of the humus [which is a fraction of soil organic matter].
[1]
They share similar structure with humic acids, with differences being the carbon and oxygen contents, acidity, and degree of polymerization, molecular weight, and color.
[2]
Fulvic acid remains in solution after removal of humic acid from humin by acidification
[3, 4]
. Humic and fulvic acids are mainly produced
