Abstract The emission of air pollutants from various industries is a major contributor to environmental pollution. removal these before they are discharged into the environment has become an important means controlling Biochar attracted increasing attention because its low cost, high porosity, large specific surface area, abundant functional groups, and capacity. physicochemical properties biochar greatly affected by feedstock types, preparation, modification conditions. For this reason, capacity propensity for removing rather variable. To understand existing research status grasp latest progress, systematic review on different highly needed. Based recent research, paper systematically analyzes summarizes preparation methods commonly used six (SO 2 , H S, CO Hg 0 VOCs, NH 3 ), as well performance mechanisms. Then, potential influencing factors (preparation parameters, characteristics biochar, conditions) discussed. Finally, regeneration suggestions, future perspectives proposed. Graphical

Biochars have potential to provide agricultural and environmental benefits such as increasing soil carbon sequestration, crop yield, fertility while reducing greenhouse gas (GHG) emissions nitrogen leaching. However, whether these effects will sustain for the long-term is still unknown. Moreover, were observed mostly in highly weathered (sub-) tropical soils with low pH organic (SOC). The northern colder boreal regions typically higher SOC undergo continuous freeze-thaw cycles. Therefore, of biochars may be different from those other climates. only a few biochar studies been conducted regions. We aimed assess on GHG emissions, yield-normalized non-CO 2 (GHGI), N dynamics soils. For this, we collected data four existing Finnish field experiments during 2018 growing season. Jokioinen (Stagnosol), Qvidja (Cambisol), Viikki-1 Viikki-2 (Umbrisol), where applied, 2, 8, 7 years before, respectively. mineral N, microbial biomass measured all fields, whereas, additional measurements plant contents leaching Qvidja. increased CO efflux Viikki-2, there no statistically significant fluxes O or CH 4 , but Qvidja, tended reduce at peak emission points. tendency seemed silt content lower initial carbon. demonstrated yield by 65% reduced GHGI 43% Viikki-2. In increment biomass, uptake, use efficiency, reduction NO 3 − –N spruce attributed its ability retain –N, which could linked significantly specific surface area. hence losses, has implications sustainable management fertilization.

Abstract Biochar is an extremely valuable carbon black material used since the Pre‐Columbian Era in Latin America and known for its properties to promote soil fertility sustain crop production. Modern civilization has followed footsteps of ancient civilizations prepared nano‐sized biochar (nano‐BC). The synthesis nano‐BC can be achieved using different feedstock materials via pyrolysis, yielding bulk‐BCs which are mechanical transformed into nano‐BCs, final value‐added product. This review provides insights structural, functional, elemental concerning synthesis, surface including functional groups, stability. Moreover, prospects improving physicochemical CEC, nutrient availability, water retention, buffering capacity discussed with agricultural implications. Mechanistic have been provided regarding how improve health could plant growth physio‐biochemical properties, further pave way application resilience abiotic stress factors. Last, limited studies conducted that elucidate potential negative effects contaminant mobilization residual these also critically discussed. Above all, as a beneficial amendment boost production enhance fertilities.

Abstract The use of inorganic nitrogen (N) fertilizers has increased drastically to meet the food requirements world's growing population. However, excessive chemical fertilizer caused a series soil and environmental problems, such as hardening, lower efficiency (NUE), nitrate pollution water sources, nitrous oxide emissions, etc. In this review, we aimed elaborate discuss role engineered biochar in inducing stability water-stable macroaggregates, improving N transformation, utilization address current uncertainties loss maintaining quality. Firstly, elucidated characteristics quality work multifunctional player ecosystem promote resource utilization, conservation, preservation. Secondly, discussed how modulates macroaggregates transformation enhance plant response under various toxic or deficient conditions soil. Thirdly, biological fixation, mediating nirK , nirS nosZ genes conversion 2 O decreasing denitrification emission was reviewed. Altogether, suggest that amendment can regulate reduce input, improve metabolism, finally, NUE crop growth. To best our knowledge, is first time evaluate combined interactions "engineered × growth,” providing advantages over increasing productivity separately with aim enhancing together on sustainable basis.

Tea plantations commonly receive substantial quantities of nitrogen (N) fertilizer, with potential for considerable N loss to occur. This study assessed retention in acidic tea plantation soil and examined how different biochar application rates fertilizer combinations affect dynamics, highlighting the importance innovative technologies monitor enhance supply management. research adopted a modified 2-week aerobic incubation ion-exchange membrane (IEM) techniques evaluate following early-summer top-dressing as influenced by various combinations. We quantified amount mineralized soils during summer. Our results show that enhances not increasing mineralization directly but improving mineral retention. Notably, threshold effect was identified at 20–30 tonnes ha−1. The window maximizing effectiveness inorganic fertilizers applied summer months could only be 2–4 weeks. use biochar-based organic can this period enhancing availability soil. Measuring via incubations exposure using IEM technology effectively elucidated dynamics period.

Abstract While the potential of biochar (BC) to immobilize potentially toxic elements (PTEs) in contaminated soils has been studied and reviewed, no review focused on use BC for enhancing phytoremediation efficacy PTE-contaminated soils. Consequently, overarching purpose this study is critically effects mobilization, phytoextraction, phytostabilization, bioremediation PTEs Potential mechanisms interactions between are also reviewed detail. We discuss promises challenges various approaches, including environmental implications, application The properties (e.g., surface functional groups, mineral content, ionic π-electrons) govern its impact (im)mobilization PTEs, which complex highly element-specific. This demonstrates contrary PTE mobilization highlights possible opportunities using as a mobilizing agent PTEs-contaminated

Biochar, known as “Black Gold”, has become a novel approach with potential benefits for soil amendment, such improving physicochemical properties, reducing greenhouse gas emissions, and enhancing fertility. The previous research studies mainly focus on exploring different methods the improvement of biochar enriched nutrients fertilizers; however, migration transformation mechanisms these induced by are yet to be extensively investigated. This paper provides an overview recent advances in application amendment focusing properties improvement. Biochar positively alters microbial-mediated reactions C N cycles, i.e., mineralization N, N2 fixation, thus maximizing use efficiency losses. Moreover, reactive surfaces where P K ions retained microbial biomass exchange sites, leading increasing availability plants uptake. In addition, toxic substances ecological risks were also reviewed discussed, thereby providing baseline reference guiding significance future applications promising amendments.
