“…Therefore, the effectiveness of the phytoremediation process conducted by plants is significantly influenced by their growth as measured by per cent growth rate and relative growth rate (Mustafa and Hayder , 2021 ; Ustiatik et al. , 2022 ). Many plants show the ability to hyperaccumulate mercury (Chamba et al.…”

Mercury contamination from human activities is a severe environmental problem. The low cost of rhizofiltration of heavy metal-contaminated environments is causing an increasing interest in these technologies. The present study demonstrates the effectiveness of mercury removal from water by phytoremediation using S. natans. Plants cultured and collected from the environment were used. The study used Hoagland’s liquid medium contaminated with mercury: 0.15, 0.20, and 0.30. The bioconcentration factor obtained was 275–780. The relative growth rate was up to 0.12 g/gd and was much better for cultured plants than those collected from the environment. The removal rate of toxic metal was up to 94%. Total protein increased for cultures plants by up to 84%, while it decreased by up to 30% for those taken from the environment. Total chlorophyll for cultured plants decreased by up to 54%, which could be due to the toxic effect of the metal.

“…Both maize and rice intercropping could not substantially alter the soil microbial a diversity; however, it strongly influenced the microbial community structure. In the two intercropping systems, the potential functions of 28 potential beneficial genera included the following: the generation of IAA (Bal et al, 2013), nitrogen fixation (Hayat et al, 2010;Shahrajabian et al, 2021), soil mercury content reduction (Ustiatik et al, 2022), the degradation of polycyclic aromatic hydrocarbons (Zhao et al, 2021), antibacterial functions (Mosquera et al, 2020), antimycotic functions (De Brito et al, 2022), aluminum tolerance (Silambarasan et al, 2022), salt and alkali resistance , phosphate solubilization (Chhetri et al, 2021;Saadouli et al, 2021), siderophores (Jamalzadeh et al, 2021;Nie et al, 2022), nitrification (Peng et al, 2021), etc. In the control group, the potential functions of the 15 potentially beneficial genera were as follows: the nitrogen cycle (Zhang et al, 2022), antibiotic functions (Nakkeeran et al, 2021), heavy metal resistance (Zhai et al, 2020;Sharma et al, 2022), phosphate solubilization (Huang et al, 2021;Duan et al, 2022), improved photosynthesis (Katsenios et al, 2021), nitrification (Li et al, 2022), etc.…”

Aconitum carmichaeli Debx. is a traditional Chinese medicine that is cultivated in China and Japan. However, the monoculturing of this herb substantially decreases soil quality. Therefore, scientific planting management is crucial for resolving the current problems in the cultivation of A. carmichaeli. In this study, we conducted a comparative study on the soil environmental characteristics, herb growth and quality of A. carmichaeli intercropping with five local crops in two different areas. Herb growth and quality, including biomass and secondary metabolites, and rhizosphere soil environmental characteristics were measured. The results showed that the intercropping with the five local crops substantially improved the A. carmichaeli biomass and polysaccharide content, decreased the disease index, and altered three monoester diterpenoid alkaloids and three diester diterpenoid alkaloids accumulations. The intercrops also increased the soil pH, nitrogen-cycling-gene abundances, and potentially beneficial microorganism abundances, and it also changed the soil nutrient levels. Moreover, these intercropping patterns could alleviate the continuous cropping obstacles of A. carmichaeli. According to a comprehensive evaluation of the A. carmichaeli growth and quality, as well as the soil quality, the best intercropping systems were the A. carmichaeli intercropping with rice, maize, and peanut. In summary, the strip-intercropping systems could improve the A. carmichaeli growth and soil quality, and be beneficial to the sustainable ecological planting of A. carmichaeli.

“…The association contributes to plants' adaptation and proliferation in areas close to an active volcano. Moreover, the beneficial microorganism can be used as biofertilizers to promote plant growth in degraded areas, e.g., post-volcanic eruption and heavy metals contamination more efficiently due to the microorganisms survive under unfavorable environments (Rincón-Molina et al 2020; Ustiatik et al 2022a).…”

“…The beneficial microorganisms exhibit particular traits related to the production of plant growth-promoting substances, such as ammonium from free N 2 in the air (free-living diazotrophic), indole acetic acid, and siderophores (Ustiatik et al 2021a; Ustiatik et al 2022b). After disturbances, microorganism abundance (bacteria and fungi) is higher in the rhizosphere area of pioneers (indigenous) plants in order to survive under unfavorable environments (Ustiatik et al, 2021b;Ustiatik et al, 2022a). Microorganisms require metabolite products from plants, such as polysaccharides from root exudates.…”

Volcanic eruptions cause large-scale damage and leave piles of volcanic material that destroy plants, agricultural lands, animals, and soil microorganisms, decreasing soil fertility. Therefore, it is necessary to accelerate soil fertility recovery in post-volcanic eruption areas to resume agricultural activities. This study aims to elucidate the effect of volcanic deposits on soil fertility as well as explore tolerant plants and bacteria after Mt Semeru eruption. Soil, volcanic ash, and plant samples were collected from Pronojiwo Sub-regency, Lumajang Regency, East Java, Indonesia. Soil and volcanic ash chemical properties were analyzed (pH, available and total phosphorus (P), potassium (K), magnesium (Mg), and calcium (Ca) content). Bacteria were isolated and enumerated, then tested for P solubilization (PSB). The result showed that 3 months after Mt Semeru's eruption, the first succession was fern, moss, and fungi. Some local plants (banana and coconut) emerge new shoots and recover. A high total P (137.32 mg/kg) with neutral pH 6.8 was found in the volcanic ash. Total P and available P were higher at the closest distance from the crater, and soil pH controlled P availability in the soil covered with volcanic deposits. Also, the thickness and distance from the crater strongly affect organic C, which reduces the PSB population from 10 3 to 10 4 CFU/g, compared to unaffected areas. The bacteria exhibited P solubilization activities even under harsh environmental conditions. Thus, accelerating soil fertility restoration by adding organic materials and inoculating beneficial bacteria (such as PSB) in the post-eruption area is essential as the bacteria benefit both soil fertility recovery and agriculture sustainability in degraded lands (e.g., post-eruption).
