The global exponential rise in greenhouse gas (GHG) emissions over the last few decades has triggered an urgent need to contextualize low-cost and evergreen technologies for restraining GHG production enhancing soil carbon sink. GHGs can be mitigated via incorporating biochar into matrix sequestrate mineralized a stable form upon organic matter decomposition soil. However, efficiency of using offset from terrestrial ecosystems is still debatable. Moreover, literature, shows high functionality short-term laboratory studies, but it minimal or negative impacts field-scale experiments, leading conflicting results. This paper synthesizes information on ability mitigate dioxide (CO2), nitrous oxide (N2O), methane (CH4) biomass, with emphasis cropland soils. feedstock type, pyrolysis temperature, application rate factors showed significant effects controlling effectiveness emissions. Our study demonstrates that biochar, taken as whole, seen powerful easy-to-use tool halting rising tide Nonetheless, future research should focus (i) identifying other indirect related physicochemical characters (such pH/EH CaCO3 contents) may control (ii) fabricating aged biochars low nitrogen footprints, (iii) functionalizing biologically activated suppress CO2, CH4, N2O Overall, our paradoxical findings highlight functionalize modern capacity abate locking up their release carbonaceous lattice biochar.

Biochar as an Environment-Friendly Alternative for Multiple Applications

Sustainability, Journal Year: 2023, Volume and Issue: 15(18), P. 13421 - 13421

Published: Sept. 7, 2023

The climate crisis and years of unsustainable agricultural practices have reduced soil fertility crop yield. In addition, lands contribute more than 10% greenhouse gases (GHGs). These concerns can be addressed by using biochar for carbon neutralization, environmental restoration, management. Biochar has a role in nitrous oxide methane gas emission mitigation from soil. New methods are needed to link belowground processes functioning multi-species multi-cultivar agroecosystems. intricate relationship between the composition microbial communities, along with its impacts on functions within rhizosphere, constitutes highly perplexing elusive subject genomics. present review discusses how mitigate change, enhance sequestration, support productivity. could potential solution microplastics heavy metal contamination.

Rice Yield and Greenhouse Gas Emissions Due to Biochar and Straw Application under Optimal Reduced N Fertilizers in a Double Season Rice Cropping System

Agronomy, Journal Year: 2023, Volume and Issue: 13(4), P. 1023 - 1023

Published: March 30, 2023

This study aimed to investigate the impacts of straw and biochar on greenhouse gas (GHG) emissions grain yield in a double rice cropping system under optimal N fertilizer reduction. Conventional fertilization (CF) was used as control group, treatments included 15% less nitrogen (OF), together with (S) or (B) applied different conditions, namely CF + S, B, OF B. The effects soil CH4 N2O were studied, changes physicochemical properties analyzed. results showed that relative CF, S increased cumulative by 11.80% 2.35%, respectively, while B resulted significant reductions 27.80% 28.46%, respectively. Biochar effective reducing emissions, further potential, achieving best 30.56% 32.21%, Although reduced yields 0.16%, this difference within reasonable limits; remaining 2.55% 3.47%. global warming potential (GWP) 27.93% 28.63%, ultimately emission intensity (GHGI) 30.42% 30.97%. Both organic matter, NH4+-N, NO3−-N contents, pH, which may be mechanism regulating GHG emissions. Overall, is beneficial for better agronomic pattern season growing areas.

The mitigation of greenhouse gas (GHG) emissions and water usage optimization in rice cultivation is challenging for many agricultural countries, including Thailand, who have set goals reaching net zero coping with droughts caused by climate change. Alternate wetting drying (AWD) biochar application are possible practices achieving cleaner production through reduction GHG consumption. However, these methods' potential varies site, especially areas limited control levels. This study assessed the effects AWD at different levels (10, 15, 20 cm below soil surface) straw on emissions, yield production, use, characteristics, economic aspects. was conducted over two seasons: a major season 2022 second 2023 field Kalasin Province, northeastern Thailand.
