“…Similarly, in perennial ryegrass the combination of mycorrhizal fungi (R. intraradices) and humic acids spray when applied on the substrate as pre-sowing was more effective in enhancing root biomass and chlorophyll biosynthesis than either products applied alone (Nikbakht et al, 2014). Similar synergistic action between mycorrhiza, sea weed extract and humic acids also has been reported in tobacco (Moradi et al, 2019).…”

It is widely accepted that the symbiotic arbuscular mycorrhizal fungi (AMF) play a key role in sustainable production systems in rice cultivation and they readily form a symbiotic relationship with these fungi. Four species consortium of AMF, Funneliformis mosseae, Rhizophagus intraradices, Clariodeoglomus etunicatum and Glomus aggregatum, produced through in vitro production system and formulated with organic biostimulants viz. humic acids and sea weed extract were tested in this experiment, both for direct seeded and transplanted paddy, under anaerobic cultivation system. AMF inoculated fields produced significantly higher yield than non-inoculated field. AMF inoculants formulated with a blend of humic acids and seaweed extract produced significantly higher grain yield than the inoculants formulated with humic acids alone, in both the cultivation systems. Effect of AMF inoculation was highly pronounced in transplanted paddy than direct seeded paddy, resulted in highest grain yield, highest grain weight, better grain filling rate and highest tiller production. It can be concluded that AMF inoculants can be potentially used for rice cultivation under anaerobic water management system, both for direct seeded and transplanted paddy and the nature of biostimulants used in the formulation also play a key role in the efficacy of AMF inoculants. Our findings contribute to the growing global consensus that mycorrhizal inoculants could play a role in sustainable rice production systems of the future, when used appropriately.

“…The increased plant height is a response to AMF, which helps in the appropriate absorption of essential nutrients. Furthermore, the inoculation of this fungus to plant roots causes the production of various hormones, such as auxin and gibberellins, and is effective in increasing the plant height and, consequently, the number of leaves [32]. It also improves water and nutrient uptake, photosynthesis potential, and carbohydrate production by altering the root morphology and thereby increasing shoot and root growth.…”

Growth and Antioxidant Responses of Lettuce (Lactuca sativa L.) to Arbuscular Mycorrhiza Inoculation and Seaweed Extract Foliar Application

et al. 2022

Biofertilizers, such as arbuscular mycorrhiza fungi (AMF) and seaweed extract (SWE), have been effective in environmental and agricultural ecosystems. In this study, the effects of AMF, SWE, and their co-application were assayed on the growth and antioxidant potential of lettuce plants. The experiment was conducted as a factorial based on a completely randomized design with two factors and four replications under greenhouse conditions. The first factor was AMF (Glomus mosseae) at two levels consisting of AMF application (20 g pot−1), and without using AMF; and the second factor was SWE foliar spraying (Ascophyllum nodosum) at 0.5, 1.5 and 3 g L−1 concentration. The results revealed that the highest root colonization (85%) belonged to AMF and SWE (3 g L−1) × AMF; the lowest colonization rate (65%) was observed for AMF × SWE (0.5 g L−1) treatment. The highest growth parameters (leaf number, shoot and root fresh weight, head diameter), biochemical traits (total soluble proteins, carbohydrates content) and TAA, total antioxidant activity by FRAP method and ascorbic acid, total phenolics, and flavonoids content were obtained with the co-applications. Therefore, the best results of the evaluated traits were achieved with AMF × SWE (3 g L−1). The TAA value was increased three-fold compared to the control. Total phenolics and flavonoids content were 2.24 and 6.59 times higher than the control, respectively. On the other hand, leaf dry weight was decreased with the further growth of the plants. Overall, the co-application of AMF with SWE can be recommended to producers as an alternative and environment-friendly strategy to improve the qualitative and quantitative traits of the lettuce crop.

“…Considering that the generative pattern of mango is more or less similar to cocoa and coffee, the application of those findings could apply to the crops in tropical regions. As indicated earlier, the application of FA improved the growth performances of coffee seedlings (Justi et al, 2019) and also of tobacco (Moradi et al, 2019), whereas in oil palm, the use of FA isolated from palm oil mill effluent as urea coating reduced 50% ammonia volatilization more effective than HA (Rosliza et al, 2009). Moreover, El-Boray et al (2012) reported that the combination of FA application with selected micronutrients (Fe, Za, and Mn) and a consortium of microbes (Serratia sp.…”

“…FAs have also been studied for their beneficial effect on soils and crops. Some researchers have published their results showing a great potential of FAs as a plant growth stimulator, such as on rice and radish (Khang, 2011), vegetables (Yang et al, 2014), safflower (Moradi et al, 2017), coffee seedlings (Justi et al, 2019), tobacco (Moradi et al, 2019) and wheat (Sootahar et al, 2020). Also, it was reported by Yang et al (2013) that the application of FAs on soils significantly improved soil-P availability.…”

Fulvic acid – a small but powerful natural substance

Humic substances are defined as the result of the decomposition of any organic matter, and they consist mainly of humin, humic, and fulvic acids. Compared to humin, humic acids and fulvic acid (FA) are the most explored compounds. However, FAs are less studied than humic acids because of the usually small residual quantities. Considering that its potential for bioactivity is stronger than that of humic acids, the current review was performed to evaluate the effectiveness of FA application for crops and soils and its potential as an immuno-modulator for humans. The wide application of FA is challenged by two main factors affecting the quality and the effectiveness, i.e., the type of raw material and extraction method. Lignite, low-energy coal, is the most common material for FA production besides bog, peat, and compost. Fulvic acid extraction is done through several methods, i.e., hydrogen peroxide (H2O2), alkaline (NaOH/KOH), and/or water. The latest modified method shows that the combination of H2O2 with microwave power can recover a considerable amount of FA. However, it is still difficult to apply this method for industrial scale. Due to highly specified characteristics, FA showed a great potential to improve crop performances and soil health, making it strategic for supporting sustainable agriculture in the future through biotic and abiotic stress alleviations and sustainable yield achievement, including various plantation crops and biotechnological approach. For medicinal purposes, some studies have shown highly promising results, especially as an immuno-modulator and in combating neurodegenerative disorders as well as for cancer therapy and health food fortification, which might be in line with the new paradigm so-called One Health approach. The future market of FA is also estimated to grow in a very attractive economic value. However, as data are still limited, the wide range of potential use should encourage concerted and wide research and product development efforts to achieve sustainable agriculture and human health.
