Biochar for agronomy, animal farming, anaerobic digestion, composting, water treatment, soil remediation, construction, energy storage, and carbon sequestration: a review

Environmental Chemistry Letters, Journal Year: 2022, Volume and Issue: 20(4), P. 2385 - 2485

Published: May 7, 2022

Abstract In the context of climate change and circular economy, biochar has recently found many applications in various sectors as a versatile recycled material. Here, we review application biochar-based for carbon sink, covering agronomy, animal farming, anaerobic digestion, composting, environmental remediation, construction, energy storage. The ultimate storage reservoirs are soils, civil infrastructure, landfills. Biochar-based fertilisers, which combine traditional fertilisers with nutrient carrier, promising agronomy. use feed additive animals shows benefits terms growth, gut microbiota, reduced enteric methane production, egg yield, endo-toxicant mitigation. Biochar enhances digestion operations, primarily biogas generation upgrading, performance sustainability, mitigation inhibitory impurities. composts, controls release greenhouse gases microbial activity. Co-composted improves soil properties crop productivity. Pristine engineered can also be employed water remediation to remove pollutants. added cement or asphalt, thus conferring structural functional advantages. Incorporating biocomposites insulation, electromagnetic radiation protection moisture control. Finally, synthesising materials requires additional functionalisation.

Biochar and Its Broad Impacts in Soil Quality and Fertility, Nutrient Leaching and Crop Productivity: A Review

Agronomy, Journal Year: 2021, Volume and Issue: 11(5), P. 993 - 993

Published: May 17, 2021

Biochar is gaining significant attention due to its potential for carbon (C) sequestration, improvement of soil health, fertility enhancement, and crop productivity quality. In this review, we discuss the most common available techniques biochar production, main physiochemical properties biochar, effects on including physical, chemical, biological parameters quality fertility, nutrient leaching, salt stress, addition, impacts addition salt-affected heavy metal contaminated soils were also reviewed. An ample body literature supports idea that amended with has a high increase concomitant in structure, use efficiency (NUE), aeration, porosity, water-holding capacity (WHC), among other amendments. However, increases biochar-amended are frequently reported coarse-textured sandy compared fine-textured fertile soils. effect microbial community composition abundance.

Biochar effects on crop yields with and without fertilizer: A meta‐analysis of field studies using separate controls

Soil Use and Management, Journal Year: 2019, Volume and Issue: 36(1), P. 2 - 18

Published: Sept. 17, 2019

Abstract The added value of biochar when applied along with fertilizers, beyond that the fertilizers themselves, has not been summarized. Focusing on direct comparisons between additions (≤20 t ha −1 ) – separately considering addition or inorganic ( IF and/or organic amendments OA and two different controls (with without ), we carried out a meta‐analysis to explain short‐term (1‐year) field responses in crop yield across climates, soils, biochars management practices worldwide. Compared non‐fertilized control, 26% CI : 15%–40%) increase was observed use only, whereas caused 48% 30%–70%) increase. 15% 11%–19%) yield, indicating as effective increasing yields combination. alone did regardless control considered. Whereas short term, liming may have partly contributed beneficial effect (>90% plant‐derived) , separate using those studies reported for years after single application showed 31% 17%–49%) over time (≥ 3 years), which denotes influence properties other than (i.e. an CEC ). Our results also suggest rates > 10 do contribute greater (at least term). Data limitations precluded identification feedstock, production conditions climatic bias. As response less result zones soil type fertilizer (chiefly N additions), choice nutrient should be priorities future research development region.

Abstract This review summarizes the influences of pyrolysis conditions and feedstock types on biochar properties how in turn affect soil properties. Mechanistic evidence biochar's potential for enhancing crop productivity, carbon sequestration, nutrient use efficiency are also discussed. The identifies knowledge gaps, limitations, future research directions large‐scale biochar. Both pyrolytic parameters considered to be main factors controlling such as content, recalcitrance, pH. Biochar produced at low temperatures may improve availability yield acidic alkaline soils, whereas high‐temperature enhance long‐term sequestration. can inorganic organic fertilizers by microbial functions reducing loss, thereby making nutrients more available plants. Integration chemical or generally provides better management most soils. Although degraded it is not a panacea; such, soil‐ crop‐specific needed order ensure optimum agricultural sustainability.
