Quinones are also responsible for the formation of reactive oxygen species (ROS) in
humic acids, which are useful for wound healing and have bactericidal properties (Melo et al., 2016).
In late 2018, University of Alberta researchers published a paper titled, "Soil
humic acids degrade CWD prions and reduce infectivity." I immediately read the fascinating results, finding myself floored by the outcome.
Inclusion of enzymes and organics acids such as
humic acids have been observed to improve digestibility of poor protein sources such as CM.
Considering the importance of studies of
humic acids (HA) in the formation of quality seedlings, it should be emphasized that the use should not occur in an empirical way, since the biological activity of HA is dependent on the source, applied concentration and plant genotype (BALDOTTO and BALDOTTO, 2014).
Amorphous iron (Fe) oxides in these soils form low-solubility complexes with phosphate, reducing the availability of this anion (Devau et al., 2011; Fink et al., 2014), which can also be influenced by
humic acids (HAs) (Gerke, 2010).
Coating of KCl with
humic acids may be a strategy to avoid loss and supply K over the plant cycle.
Humic substances (HS), the main constituent of organic matter, present heterogeneous mixture of organic compounds aggregated by weak intermolecular interactions of hydrophobic nature and by hydrogen bonds (Matilainen et al., 2011; Valencia et al., 2013), which are fractionated in
humic acids (HA), fulvic acids (FA) and humins (Baldotto et al., 2013); HS have a structural complexity due to the presence of organic functional groups that provide several functions in the nutrition of plants and improvement of the physical and chemical properties of the soil.
Thus, our study aimed to evaluate the humification rates and structural composition of
humic acids in the suspended soil in the tropical forest of South Vietnam.
