Abstract Biochar and compost application in soil has been proved as an environmental management remediation strategy for upgrading quality growth-promoting microorganisms. A detailed examination of the fluctuations stoichiometric interactions between β-glucosidase (BG), N-acetylglucosaminidase (NAG), leucine aminopeptidase (LAP), acid phosphatase (AP) after applying biochar to heavy metal soils was conducted paper. However, stimulated activity AP inhibited BG, NAG, LAP. Compost biochar-compost might strengthen LAP, activities. Redundancy analysis discovered that crucial parameters affected enzyme were TN, NO 3 − -N, TP. ratio C/N, C/P, N/P with biochar, compost, could be changed. While alleviating P-limitation under Cu stress, may also alleviate C-limitation As, Cd, Zn stress. alleviated heavy-metal (Cu, Zn) polluted soil. This work will help us further understand stoichiometry energy restrictions on ecological functional enzymes.

Biochar Acts as an Emerging Soil Amendment and Its Potential Ecological Risks: A Review

Energies, Journal Year: 2022, Volume and Issue: 16(1), P. 410 - 410

Published: Dec. 29, 2022

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.

Biochar-Acid Soil Interactions—A Review

Sustainability, Journal Year: 2023, Volume and Issue: 15(18), P. 13366 - 13366

Published: Sept. 6, 2023

Soil acidity is a major problem of agriculture in many parts the world. causes multiple problems such as nutrient deficiency, elemental toxicity and adverse effects on biological characteristics soil, resulting decreased crop yields productivity. Although number conventional strategies including liming use organic inorganic fertilizers are suggested for managing soil but cost-effective sustainable amendments not available to address this problem. Currently, there increasing interest using biochar, form biomass derived pyrogenic carbon, while improving health fertility. However, biochar varies properties due wide diversity biomass, variable production conditions and, therefore, its application different soils can result positive, neutral or negative requiring an in-depth understanding biochar-acid interactions achieve best possible outcomes. Here, we present comprehensive synthesis current literature management biochar. Synthesis showed that biochars, enriched with minerals (i.e., usually produced at higher temperatures), most effective pH, basic cation retention promoting plant growth yield. Moreover, mechanism amelioration types, i.e., high temperature biochars low proton consumption their functional groups. We also provide mechanistic between soils. Altogether, review will guidelines agricultural practitioners selection suitable reclamation acidity.

An effective global biochar application strategy for reducing global cropland nitrogen emissions without compromising crop yield: Findings from a global meta-analysis and density functional theory calculation

Environmental Technology & Innovation, Journal Year: 2024, Volume and Issue: 33, P. 103546 - 103546

Published: Jan. 20, 2024

Biochar is widely used to mitigate nitrogen (N) emissions in global croplands. However, its effectiveness varies due spatial disparities external factors such as soil properties and climate conditions, well biochar characteristics pH carbon content. In this study, we a molecular model assess the distinct impacts of on N emissions. We employed back-propagation neural network optimized using genetic algorithm (GA-BPNN) simulate croplands, utilizing data from 351 peer-reviewed papers. Then, application strategy aimed at optimizing reduction across croplands was devised by aligning parameters. Our findings indicate that high electrophilic nucleophilic biochar's reactive surface significantly contribute The GA-BPNN-based machine learning (ML) technology demonstrated superior predictive performance (with R2 ranging 0.47 0.69) predicting changes post-biochar compared other algorithms. simulations show increases NH3 volatilization but achieves most significant cropland emissions, amounting 16.04 Tg yr-1 representing approximately 28.45% estimated total all while preserving crop yields. Therefore, with specific parameters environmental conditions could be promising for mitigating addressing degradation.
