A review on humic substances: Their significance in agriculture as stimulations of plant physiological growth and development
Gowthamchand NJ and Sujaina M
Currently, agricultural production management approaches are greater emphasis on environmental sustainability. Humic substances (HSs) are the most abundant component of soil organic matter, formed through the breakdown of organic material through a series of biochemical processes. HSs with distinctive physiochemical and biochemical features, such as humic acid, fulvic acid, and humin, play an important role in crop physiological growth and development. The stimulatory effects of HSs on plant growth might be indirect (Through increased fertiliser efficiency or reduced soil compaction) or direct (through improvement of total plant biomass). The effect of HS on plant development is dependent on the source, concentration, and molecular weight of the humic fraction. The physiological effects of humic substances on plant development and metabolism are investigated. This study provides a summary of the research results on humic compounds diverse regulatory functions and their influence on plant physiological growth and development.
