“…This nutrient concentration was higher than the results of research by Arjumend et al [69] which obtained values of 0.35% N, 5.05 mg P kg -1 and 0.36 cmol(+) K kg -1 in the HA application at a dose of 200 mg kg -1 . The increase in soil nutrient status was possibly due to the influence of HA which can inhibit urease activity, so that N loss through leaching and volatilization processes can be reduced [70,71]. The same thing also happened to P, where the HA application was possible to increase the availability and absorption of these nutrients by reducing the deposition rate of calcium phosphate (Ca-P) or aluminum phosphate (Al-P) because of the potential to form metal bridges with HA and/or FA [72,73].…”

Humic acid (HA) has been reported to increase plant growth and crop yields, as well as improve soil fertility. However, the potential utilization of HA extracted from various organic waste composts as organic amendment in suboptimal soils has not been studied in depth. The experiment used a two-factor Completely Randomized Design (CRD) with three replications. Four types of HA were used, namely bagasse HA (BHA), water hyacinth HA (WHA), market waste HA (MHA), and commercial HA (CHA). It also comprised of four doses HA i.e., 0.05, 0.10, 0.15 and 0.20% (of soil on w/w base). The results revealed that fluctuations in soil pH and nutrient release with the HA application had a variable quadratic response pattern. Organic carbon increased by 17%, while total N and available P decreased by 5% and 38.6% during the last weeks of incubation. The HA application could improve the growth response and nutrient uptake of maize significantly. CHA0.20% was the best interaction treatment which had the highest average value on dry weight and NPK uptake, which were 98.0 g pot-1, 178.8 mg plant-1, 27.4 mg plant-1 and 216.9 mg plant-1, respectively. The scanning electron microscopic (SEM) showed that HA could increase in the length and density of maize root hairs. Furthermore, the HA application significantly increased pH, CEC, C-organic content and availability of soil nutrients.

“…Humic acid (HA) is a natural organic polymeric compound produced from soil organic matter, peat, and lignin decay. It absorbs several ions to form chelates with micronutrients, which release the ions slowly and continuously 7 . HA contains many carboxyls, phenolic, carbonyl, and hydroxyl chemical groups attached to aliphatic or aromatic carbons and improves the plants’ stress tolerance, growth potential, seed germination speed and rate, crop quality, and yield, as well as the soils fertility and physicochemical properties such as permeability, aeration, granulation, and soil water holding capacity 8 .…”

In recent decades, the over-use of chemical fertilizers has imposed many environmental challenges worldwide. Nowadays, organic fertilizers such as vermicompost and livestock manure have gained a huge interest in sustainable agricultural systems. A 2-year field research was conducted as factorial based on a randomized complete block design to assay the fertilizer and humic acid (HA) efficiency on the growth responses and essential oil composition of Coriandrum sativum. The treatments were different fertilizer sources (livestock manure, vermicompost, and chemical fertilizers) and humic acid fertigation before and at the beginning of the flowering stage. The highest protein content was observed under vermicompost × HA application before flowering (0.118 μmol L−1 and 0.128 μmol L−1, respectively). Moreover, the co-application of organic fertilizers × HA at the beginning of flowering resulted in a significant increase in the photosynthetic pigments and N, P, K, Fe, Zn, and Mn content. According to the GC-FID and GC–MS analysis, linalool (55.91–63.19%), γ-terpinene (4.65–6.13%), α-pinene (2.64–5.74%), geranyl acetate (3.49–5.51%), 2-dodecanal (2.92–4.46%), menthol (1.33–3.90%), p-cymene (1.73–2.24%), and geraniol (1.25–2.15%) were the main essential oil constituents. The top linalool content was obtained by using chemical fertilizers and vermicompost × HA at the flowering onset stage. In general, the results revealed that chemical fertilizers could be replaced with vermicompost × HA and their co-application positively influenced the growth responses and the essential oil composition of coriander. Furthermore, the results obtained would be advisable to the extension section and the pioneer farmers to amend the large-scale production systems in favor of environmental health.

“…Previous studies have found that HA can improve the physical and chemical properties of soil [ 6 , 7 ], reduce the damage caused by abiotic stress, contribute to making plants more resistant [ 8 ], enhance the antioxidant system, promote making cell walls, and stabilize the metabolism of protein and sulfur-containing substances at the molecular level [ 9 ]. Furthermore, it can also promote plant growth, increase yield, and stimulate root absorption [ 10 , 11 ]. In addition, it can reduce the incidence rate of plant diseases [ 12 , 13 ].…”

In recent years, bayberry decline disease has caused significant damage to the bayberry industry. In order to evaluate whether humic acid can be used to effectively control the disease, this research examined the nutritional growth and fruit quality of bayberry, soil physical and chemical properties, soil microbial community structure, and metabolites. Results indicated that the application of humic acid not only improved the vigor and fruit quality of diseased trees, but also increased the diversity of microbial communities in the rhizosphere soil. A great increase was observed in the relative abundance of bacterial genus Mycobacterium and Crossiella; fungal genus Fusarium and Coniosporium. In contrast, a significant decrease was observed in the relative abundance of bacterial genus Acidothermus, Bryobacter, Acidibacter, fungal genus of Geminibasidium and Mycena. Analysis of redundancies (RDA) for microbial communities and soil characteristics showed that the main four variables, including available nitrogen, phosphorus, potassium, and calcium, had a great effect on the composition of bacterial and fungal communities in bayberry rhizosphere soil at the genus level. The main four variables had a greater effect on bacterial communities than on fungal communities. In addition, ABC transporter, arginine and proline metabolism, galactose metabolism, and glutathione metabolism were significantly affected by humic acid, which changed the content of 81 metabolites including 58 significantly down-regulated metabolites such as isohexonic acid and carinitine, and 23 significantly up-regulated metabolites such as acidic acid, guaninosuccinate, lyxose, 2-monoolein, epicatechin, and pentonolactone. These metabolites also significantly correlated with rhizosphere soil microbiota at the phylum, order, and genus levels. In conclusion, the results demonstrated the role of humic acid on plant growth and fruit quality, as well as rhizosphere soil characteristics, microbiota, and secondary metabolites, which provides novel insights into the control of bayberry decline disease.
