Assessing biochar's impact on greenhouse gas emissions, microbial biomass, and enzyme activities in agricultural soils through meta-analysis and machine learning

The Science of The Total Environment, Journal Year: 2025, Volume and Issue: 963, P. 178541 - 178541

Published: Jan. 17, 2025

The role of biochar in reducing greenhouse gas (GHG) emissions and improving soil health is a topic extensive research, yet its effects remain debated. Conflicting evidence exists regarding biochar's impact on microbial-mediated with respect to different GHGs. This study systematically examines these divergent perspectives, aiming investigate influence GHG agricultural soils. meta-analysis includes 2594 paired observations from 157 studies conducted between 2000 2024. It was found that increased the presence amoA nosZ genes by 39.4 % 41.7 %, respectively, while abundance nirS gene 17.8 %. led 13.1 decrease N2O emissions.

Comparative and synergistic impacts of lime and biochar on soil properties, nitrogen transformation, and microbial function in acidic soils under tobacco cropping

Frontiers in Plant Science, Journal Year: 2025, Volume and Issue: 16

Published: Feb. 7, 2025

Lime and biochar are widely utilized to enhance nitrogen utilization in crops grown on acidic soils, though each has its own set of limitations. Understanding their combined effects is crucial for optimizing soil remediation strategies. This study investigates the impact lime efficiency (NUE) a tobacco monoculture system, which been practiced 20 years acidified soils Fuzhou, southeastern China, over period from 2021 2022. Four treatments were applied: control (CK), alone (L), (B), lime-biochar combination (L+B). The results indicated that all significantly improved NUE, with increases ranging 20.07% 27.17% compared CK. Biochar (B) was more effective than treatment (L+B) showed comparable alone. Correlation analysis revealed pH exchangeable base cations facilitated transformation, thereby enhancing NUE. (L, L+B) promoted nitrification potential rhizosphere soil, whereas application (B, resulted elevated nitrate content. Microbial functional enhanced nitrification, while fostered dissimilatory reduction, improving retention. Pearson correlation demonstrated strong positive relationship between reduction both alkali-hydrolyzable contents. These findings suggest enhances promotes retention, together increasing availability. integrates these benefits, yielding offers valuable insights into synergistic use mitigating acidification management agricultural systems.

Impact of biochar application on nitrous oxide and methane emissions in rainfed cropping systems within a semiarid region

Agronomy Journal, Journal Year: 2024, Volume and Issue: unknown

Published: Oct. 17, 2024

Abstract This study investigated the impact of biochar on Zea mays L. yield and greenhouse gas (GHG) emissions in rainfed maize fields Northwest China. Four treatments were compared: unmodified control (CK), conventional nitrogen (BC0), + 20 t ha −1 (BC20), 50 (BC50). Results showed significant increases grain yields with BC20 (11.1%) BC50 (8.6%) compared to BC0. Emissions nitrous oxide (N 2 O) reduced by 14.0%–19.5% CK. Methane (CH 4 ) uptake fields, acting as CH sinks, was not significantly impacted treatments, clarifying that did alter farmland's inherent ability . Over years, addition fertilizer markedly cumulative uptake. Both net (NGHG) yield‐scaled GHG intensity (NGHGI) lowered 16.7%–23.5% 24.2%–30.3%, respectively, application. The integration effectively mitigated emission enhancement due fertilizer, mainly decreasing boosting yields. Thus, proper application would be an economical effective strategy for mitigating from cropping system semiarid regions.

This study aimed to produce livestock manure biochar decrease environmental problems from and evaluate its effectiveness as an organic fertilizer by examining the growth nutrient use efficiency of crops. A plot experiment was conducted investigate characteristics lettuce nitrogen in upland soils treated with cow biochar. The applied at rates 0, 3, 5, 7, 10 t ha−1 (referred CMB0, CMB3, CMB5, CMB7, CMB10, respectively), along inorganic (IF, NPK—200-59-12 kg ha−1). cultivation test carried out for 42 days, during which fresh weight, dry length, number leaves were measured. Nitrogen evaluated determining agronomic N apparent recovery fraction N. Overall, application rate increased, crop uptake improved. Soils CMB5 CMB7 showed higher growth, content, compared under other treatments. followed a pattern similar that productivity, levels playing significant role. In particular, N, are both related utilization, significantly treatment IF treatment. These results indicate can be enhanced through when growing crops on agricultural land. Therefore, it is suggested appropriate reduce increase thereby enabling sustainable eco-friendly agriculture.
