“…[102]. Biochar can have a high cation exchange capacity (CEC) [103,104], which means (i) it can attract and retain cations, such as calcium, magnesium, and potassium, in the soil [103,105] and (ii) bind some pollutants, including carbon dioxide and heavy metals, by exchanging cations [106]. Biochar can be stable for long periods, but its stability and other properties can also depend on the feedstock, biomass pretreatment, and pyrolysis conditions, such as the carbonization temperature and residence time [107,108].…”

Biochar could be a brilliant additive supporting the anaerobic fermentation process. However, it should be taken into account that in some cases it could also be harmful to microorganisms responsible for biogas production. The negative impact of carbon materials could be a result of an overdose of biochar, high biochar pH, increased arsenic mobility in the methane fermentation solution caused by the carbon material, and low porosity of some carbon materials for microorganisms. Moreover, when biochar is affected by an anaerobic digest solution, it could reduce the biodiversity of microorganisms. The purpose of the article is not to reject the idea of biochar additives to increase the efficiency of biogas production, but to draw attention to the properties and ways of adding these materials that could reduce biogas production. These findings have practical relevance for organizations seeking to implement such systems in industrial or local-scale biogas plants and provide valuable insights for future research. Needless to say, this study will also support the implementation of biogas technologies and waste management in implementing the idea of a circular economy, further emphasizing the significance of the research.

“…Phosphorus is one of the essential elements for plants (Arwenyo et al, 2022), and the distribution and transport of soil phosphorus affect plant growth and productivity (Xia et al, 2020, Yadav et al, 2020. S-PT is an enzyme that catalyzes the transfer of phosphate groups from donors to acceptors and is closely related to phosphorus uptake and transport.…”

Root exudates serve as crucial mediators for the information exchange between plants and soil, which is an important evolutionary mechanism for plants to adapt to environmental changes. In this study, 15 different abiotic stress models were established using various stress factors, including drought (D), high temperature (T), nitrogen deficiency (N), and phosphorus deficiency (P) and their combinations. We investigated their effects on the seedling growth of Salvia miltiorrhiza Bunge and the activities of

“…Elevating soil temperature, increasing soil pH, and decreasing water content are all feasible means to inactivate soil viruses. Traditional soil amendments (e.g., red mud, zeolite, phosphate rock, lime) that are originally applied to improve nutrient availability or immobilize heavy metals (Arrobas et al, 2022 ; Arwenyo et al, 2022 ; Battisti et al, 2022 ; Christensen et al, 2022 ; Doni et al, 2021 ; Yang et al, 2022 ) may disinfect COVID‐19 successfully, since all of them elevate soil pH so that capsid (protein) can be destroyed. Among these amendments, liming with CaO may serve as a promising strategy for soil disinfection, since the aforementioned three disinfection mechanisms can be achieved simultaneously.…”

Colloidal contaminants and pathogens are widely distributed in soil, whose tiny sizes and distinct surface properties render unique environmental behaviours.Because of aging, colloids can undergo dramatic changes in their physicochemical properties once in the soil environment, thus leading to diverse or even unpredictable environmental behaviour and fate. Herein, we provide a state-of-art review of colloid aging mechanisms and characteristics and implications for risk mitigation. First, we review aging-induced formation of colloidal contaminants and aging-associated changes. We place a special focus on emerging nanoplastic (NP) contaminants and associated physical, chemical, and biological aging processes in soil environments. Second, we assess aging and survival features of colloidal pathogens, especially viruses. Viruses in soils may survive from several days to months, or even several years in groundwater, depending on their rates of inactivation and the reversibility of attachment. Furthermore, we identify implications for risk mitigation based on aging mechanisms. Hotspots of (photo)chemical aging of NPs, including plastic gauzes at construction sites and randomly discarded plastic waste in rural areas, are identified as area requiring greater research attention. For COVID-19, we suggest taking greater care in regions where viruses are persist for long periods, such as cold climate regions. Soil amendment with quicklime (CaO) may act as an effective means for pathogen disinfection.Future risk mitigation of colloidal contaminants and pathogens relies on a better understanding of aging mechanisms and more sophisticated models accurately depicting processes in real soil environments.
