Functions and development of humic acid and fulvic acid.

Humic Acid

humic acid functional groups

Humic Acid development

The functional groups (mainly carboxyl groups and phenolic hydroxyl groups) in humic acid can give active hydrogen ions. So humic acid shows weak acidity and chemical reactivity.  With strong ion exchange ability and complex (chelation) cooperation.

The quinone group, carboxyl group and phenolic hydroxyl group of humic acid make it bioactive. The “five functions” of humic acid in agriculture (soil improvement, fertilizer enhancement, growth stimulation, stress resistance and quality improvement) have been guiding the application and progress of humic acid in agriculture.Read More
