“…Regarding the stimulating effects of HA extracts, many other studies have reported similar results on other plants. For example, foliar application of HA at the highest concentration (6%) increased the quality, growth and yield of statice cut flowers 45 . HA has been used on cucumber and has improved the nutritional balance and vitality of cucumber 46 .…”

Vermicompost (VC) is a rich source of HA that improves plant growth and yield indices such as fresh and dry weights, plant height, stem diameter, leaf area, and chlorophyll index value. In this study, the effect of foliar application of HA extracted from different types of VC enriched with bacteria and/or fertilizers, commercial HA (CHA) and indole acetic acid (IAA) on the growth characteristics of canola (Brassica napus) in greenhouse conditions were compared. According to the results, the foliar application of HA extracted from VC had complete superiority over CHA and IAA in most traits except for the leaf number. Furthermore, the highest level of foliar application of HA (600 mg L−1) enriched with Azotobacter chroococcum (21Az) + Pseudomonas fluorescens (Ps 59) (HA-AS) generated the highest height, diameter, leaf area, and chlorophyll index value. Also, the highest stomatal conductance and photosynthesis rate were observed with the application of 600 mg L−1 HA extracted from VC enriched with nitrogen, sulfur, and phosphorus (HA-NSP) compared to the other treatments. Besides, dry and fresh weights and seed yield under HA-NSP and HA-AS treatments were at their highest rate. Among the extracted HAs, the one extracted from the nitrogen enriched VC had the lowest efficiency. Based on the present study, the HA extracted from VC enriched with Azotobacter, Pseudomonas and NSP is recommended to increase canola growth and production.

“…Salicylic acid and humic material could act as a cut flower postharvest preservative, where they decrease the lipid peroxidation and delay the aging process (Khandan-Mirkohi et al, 2021). In addition, the activity of the antioxidant enzymes is enhanced by salicylic acid and humic material in cut flowers (Khandan-Mirkohi et al, 2021). Perhaps, this concept can be further applied in stem cutting, selling, and big tree transplanting (to preserve the root ball) to extend the shelf life for shipping and storage time.…”

The humic substance consists of humic acid, fulvic acid, and humin. Humic acid is a useful metal complexing agent, a good dispersant, and a redox agent. Humic acid showed an auxin-like activity and thus promoted root growth and development. It positively affected soil's physical, chemical, and biological properties. Hence, humic acid indirectly improved plant growth by chelating nutrients to the plant. However, humic acid converted carcinogen compounds in chlorinated water. Still, humic acid is a good compound for agricultural purposes. Humic acid can be produced in thermophilic composting, vermicomposting, and Bokashi. The humification process can occur with decomposers such as black soldier fly. Those methods can be made in farmland and even in the housing area. Extraction of humic acid is required from those production methods. However, it is not easy to extract by farmers on a small scale. Full compost and Bokashi or its tea also showed much humic acid alone. Humic acid extraction may be optional but good as crop tonic. Nonetheless, further study should be carried out. Bokashi tea and leachate with decomposer should be further studied to obtain more evidence of their benefits. With the benefit of composting and fermentation, further study on treating is required for food security.
