chemical parameters such as structure and porosity and cation exchange capacity (Bronick and Lal, 2005;Trevisan et al., 2010a;du Jardin, 2015). Humic substances are supramolecular structures of heterogenous molecules (e.g., sugar, fatty acids,polypeptides, aliphatic chains, and aromatic rings) ...
(phenolic hydroxyls) within their chemical structures, which allow them to take part in redox reactions. Thus, the ability of HS to enhance plant growth may, in part, be redox-based and be influenced by the ratio of pro- to anti-oxidants in the HS chemical structure. Pro-oxidant moieties...

(1919) postulated that HS are the light to dark-brown substances of unknown materials, which are formed in nature by the decomposition of organic matter through the actions of microorganisms or in a laboratory by oxidizing chemical reagents. Alternatively, it was suggested that humus is the ...
EDDHA Fe, with its special chemical structure, can tightly chelate with iron ions to form a stable complex that is easily absorbed by plants. Even in complex soil environments, it can effectively prevent the precipitation and fixation of iron ions, continuously provide plants with available iron ...
