Abstract

The application of biochar and nitrogen fertilizer can increase rice yield, soil organic carbon (SOC) storage and reduce greenhouse gas (GHG) emissions. However, few studies have systematically evaluated the carbon footprint (CF) and net ecosystem economic benefits (NEEB) of paddy ecosystems under long-term application of biochar and nitrogen fertilizer. Here, the life cycle assessment method was used to quantify the CF and NEEB of paddy fields under different biochar and nitrogen fertilizer application rates in 7 years. Three biochar rates of 0 (B0), 4.5 (B1) and 13.5 t ha−1 year−1 (B2) and two nitrogen fertilizer rates of 0 (N0) and 300 kg ha−1 year−1 (N) were set. The results showed that B2 significantly increased methane (CH4) emission by 38%, decreased nitrous oxide (N2O) emission by 29%, and significantly increased global warming potential by 27% compared with B0. Besides that, biochar application significantly increased ΔCSOC by 87%–173% and reduced CF by 1.6–1.8 Mg CO2 eq ha−1. Among them, CH4 and N2O emissions contributed 46%–95% of total GHG emissions, and the production and transportation of nitrogen fertilizer and biochar contributed 17%–52% of total GHG emissions. Nitrogen fertilizer application can significantly increase rice yield by 85% compared to the N0, which could bring the largest NEEB. Biochar application had a negative influence on the NEEB regardless of N application. This might be attributable to the fact that the economic gains from increased rice production and SOC caused by biochar cannot outweigh the high cost of biochar. These results suggest that the biochar application can significantly improve the SOC sequestration and reduce the CF, but also had negative effect on NEEB in paddy filed.

长期施用生物炭条件下稻田土壤固碳与生态系统净经济效益之间的权衡
施用生物炭和氮肥可以提高水稻产量、增加土壤有机碳(SOC)储量并减少温室气体(GHG)排放。然而,很少有研究对长期施用生物炭和氮肥的水稻生态系统的碳足迹(CF)和生态系统净经济效益(NEEB)进行系统评估。本文采用生命周期评估方法,量化了不同生物炭和氮肥施用量下水稻田 7 年的碳足迹和净生态系统经济效益。设定的生物炭施用量分别为 0 吨/公顷-年(B0)、4.5 吨/公顷-年(B1)和 13.5 吨/公顷-年(B2),氮肥施用量分别为 0 吨/公顷-年(N0)和 300 千克/公顷-年(N)。结果表明,与 B0 相比,B2 显著增加了 38% 的甲烷(CH4)排放量,减少了 29% 的氧化亚氮(N2O)排放量,并显著增加了 27% 的全球升温潜能值。此外,施用生物炭还能使 ΔCSOC 显著增加 87%-173%,使 CF 减少 1.6-1.8 Mg CO2 eq ha-1。其中,CH4 和 N2O 排放占温室气体总排放量的 46%-95%,氮肥和生物炭的生产和运输占温室气体总排放量的 17%-52%。施用氮肥可使水稻产量比不施用氮肥时大幅提高 85%,从而带来最大的 NEEB。无论施氮与否,施用生物炭都会对 NEEB 产生负面影响。这可能是因为生物炭增加水稻产量和 SOC 所带来的经济收益无法抵消生物炭的高成本。这些结果表明,施用生物炭可以显著提高 SOC 固碳量并降低 CF,但同时也会对水稻耕地的 NEEB 产生负面影响。

期刊介绍: GCB Bioenergy is an international journal publishing original research papers, review articles and commentaries that promote understanding of the interface between biological and environmental sciences and the production of fuels directly from plants, algae and waste. The scope of the journal extends to areas outside of biology to policy forum, socioeconomic analyses, technoeconomic analyses and systems analysis. Papers do not need a global change component for consideration for publication, it is viewed as implicit that most bioenergy will be beneficial in avoiding at least a part of the fossil fuel energy that would otherwise be used. Key areas covered by the journal: Bioenergy feedstock and bio-oil production: energy crops and algae their management,, genomics, genetic improvements, planting, harvesting, storage, transportation, integrated logistics, production modeling, composition and its modification, pests, diseases and weeds of feedstocks. Manuscripts concerning alternative energy based on biological mimicry are also encouraged (e.g. artificial photosynthesis). Biological Residues/Co-products: from agricultural production, forestry and plantations (stover, sugar, bio-plastics, etc.), algae processing industries, and municipal sources (MSW). Bioenergy and the Environment: ecosystem services, carbon mitigation, land use change, life cycle assessment, energy and greenhouse gas balances, water use, water quality, assessment of sustainability, and biodiversity issues. Bioenergy Socioeconomics: examining the economic viability or social acceptability of crops, crops systems and their processing, including genetically modified organisms [GMOs], health impacts of bioenergy systems. Bioenergy Policy: legislative developments affecting biofuels and bioenergy. Bioenergy Systems Analysis: examining biological developments in a whole systems context.
