Abstract:
... Biochar is a stable carbon-rich product loaded with upgraded properties obtained by thermal cracking of biomasses in an oxygen-free atmosphere. The pristine biochar is further modified to produce engineered biochar via various physical, mechanical, and chemical methods. The hasty advancement in engineered biochar synthesis via different technologies and their application in the field of energy and ...

Abstract:
... Soil microbial diversity consisted of both culturable and non-culturable microbes. The cultivated microbes can be identified by conventional microbiological processes. However, that is not possible for the non-culturable ones. In those cases, next-generation sequencing (NGS)-based metagenomics become useful. In this study, we targeted two very popular tea gardens of Darjeeling hills—Makaibari (Mak ...

Abstract:
... Numerous onshore oil production wells currently exist, and the petroleum hydrocarbon contamination of the surrounding soil caused by oil production wells is not well understood. Moreover, the impact of the distribution of the total petroleum hydrocarbons (TPH) in the soil on the microbiota requires further investigation. Accordingly, in this study, the distribution of petroleum hydrocarbons in the ...

Abstract:
... The levels of organic pollutants, in particular polycyclic aromatic hydrocarbons (PAHs), are increasing worldwide, yet we lack clarity on how these pollutants affect microbial communities of different trophic levels, including protists, fungi, and bacteria. Herein, we conducted soil microcosm incubation experiments to investigate the effects of pyrene, a typical PAH, on microbial communities along ...

Abstract:
... This feature article tracks 100 years of soil disinfestation, from the goal of eradicating soilborne pathogens and pests to much milder approaches, aimed at establishing a healthier soil, by favoring or enhancing the beneficial soil microflora and introducing biological control agents. Restrictions on the use of many chemical fumigants is favoring the adoption of nonchemical strategies, from soill ...

Abstract:
... Viruses are key members of Earth’s microbiomes, shaping microbial community composition and metabolism. Here, we describe recent advances in 'soil viromics', that is, virus-focused metagenome and metatranscriptome analyses that offer unprecedented windows into the soil virosphere. Given the emerging picture of high soil viral activity, diversity, and dynamics over short spatiotemporal scales, we t ...

Abstract:
... Contaminated sites from electronic waste (e-waste) dismantling and coking plants feature high concentrations of heavy metals (HMs) and/or polycyclic aromatic hydrocarbons (PAHs) in soil. Mixed contamination (HMs + PAHs) hinders land reclamation and affects the microbial diversity and function of soil microbiomes. In this study, we analyzed HM and PAH contamination from an e-waste dismantling plant ...

Abstract:
... Recent advances in molecular ecology have dramatically improved our knowledge of soil microbial diversity and offers new indicators of soil quality. The usefulness of diversity indices has never been greater as the astronomical amounts of data generated in the literature needs to be synthesized. Despite technical guidelines have been proposed to characterize soil microbiomes using high throughput ...

Abstract:
... Erythromycin is one of the most commonly used macrolide antibiotics. However, little is known currently about the environmental behavior and fate of erythromycin in soils. Here erythromycin was ¹⁴C-labeled to investigate its degradation, mineralization and bound residues (BRs) in three typical agricultural soils. Results indicated the fate of ¹⁴C-erythromycin in soils varied greatly with soils typ ...

Abstract:
... Despite the critical importance of roots within soils for supporting plant growth, the assessment of root distribution in soils remains difficult and much is unknown regarding their behaviour. In this review, we examine X-ray computed tomography (CT) as a non-invasive method for examining root distribution in soils. X-ray CT enables three-dimensional reconstruction of soil cores to accurately esti ...

Abstract:
... Soil microorganisms are indispensable for a healthy soil environment, where the fate of pesticides is contingent on microbial activity. Conversely, soil ecosystems can be distorted by all kinds of variables, such as agrochemicals. These crop protection products have been universally in use for decades in agriculture. In modern crop cultivation, fungicides are increasingly applied because of their ...

Abstract:
... The usage of reclaimed wastewater (RWW) for irrigation of agricultural soils is increasingly being acknowledged for reducing water consumption by promoting reuse of treated wastewater, and for the delivery of extant nutrients in the soil. The downside is that RWW may be a vector for contamination of soils with contaminants of emerging concern (CECs), if left uncontrolled. Its usage is anticipated ...

Abstract:
... Soil studies have reported the effect of Hexachlorocyclohexane (HCH) on soil microbial communities. However, how soil microbial communities and function shift after HCH addition into the red and purple soil remains unclear. Here, we analyzed the HCH residue fate, and the functional composition and structure of microbial communities to HCH in the two soils. Under the 100 g/ha and 1000 g/ha treatmen ...

Abstract:
... Heavy metals (HMs) and total petroleum hydrocarbons (TPHs) in soils can be detrimental to both soil microorganisms and public health. However, the effects of HMs and TPHs on microbes as well as the consequent microbial-derived health risk remains unclear in soils by local roads where citizens are clearly accessible to traffic-derived pollutants. Herein, we sampled 84 roadside soils throughout Shan ...

Abstract:
... The global declines in biodiversity and ecosystem integrity demand effective restoration. Soil microbiota are fundamentally linked to biodiversity and ecosystem restoration, as they are central to important ecological functions (e.g., nutrient cycling) and are extremely species rich. Their importance, plus the growing affordability of high-throughput sequencing, has resulted in rapid growth of stu ...

Abstract:
... Microbial communities play important roles in soil health, contributing to processes such as the turnover of organic matter and nutrient cycling. As soil edaphic properties such as chemical composition and physical structure change from surface layers to deeper ones, the soil microbiome similarly exhibits substantial variability with depth, with respect to both community composition and functional ...

Abstract:
... The use of biosolids as fertilizers in agriculture can lead to the exposure of soil biota to sulfidised silver nanoparticles (Ag₂S NPs), generated during the wastewater treatment procedures. Considering the crucial role of microorganisms on soil functions, we aimed to study the effects of 10 mg kg⁻¹ soil of Ag₂S NPs or AgNO₃ on the soil microbiome, using an indoor mesocosm. After 28 days of exposu ...

Abstract:
... The rupture of the Fundão Dam containing iron‐rich mining tailings, in 2015, was one of the worst environmental disasters in Brazil. The deposition of tailings has generated serious impacts on the soil and, as microorganisms play an important role in these environments, the recovery of the microbial community is a critical step in restoring the soil for sustainable use. Soil microorganisms and the ...
