Abstract

This study explores the application of an Atmospheric-pressure Cold plasma-based Dielectric Barrier Discharge (ACP-DBD) reactor to enhance soil fertility by increasing concentrations of nitrite, nitrate, and ammonium. The ACP-DBD system, powered by a bipolar pulsed power supply, was optimized by adjusting applied voltage, frequency, and treatment duration, with optimal plasma conditions identified at 10 kV and 20 kHz. Reactive species were analysed using Optical Emission Spectroscopy (OES). Additionally, the study investigates the reactor’s electrical characteristics and temperature fluctuations, offering insights into its operational performance and efficiency. The optimized ACP-DBD treatment (10 kV/20 kHz, 15 min) resulted in a significant enhancement of nitrogen species in the soil, with NO₃-N concentration increasing from 678.87 to 1858 mg/kg, NO₂-N concentration increasing from 0.59 to 2.06 mg/kg, and NH₄-N concentration increasing from 1.46 to 11.64 µg/kg compared to the untreated soil. To assess the impact of ACP-DBD treatment, key soil properties were analysed, including pH, electrical conductivity (EC), moisture content, bulk density and total porosity. Furthermore, X-ray fluorescence (XRF) and ICP-MS analysis were conducted for multi-element composition evaluation. Results indicated that plasma treatment influenced the concentration of various soil elements. Additionally, the plasma-treated soil was stored for 30 days to monitor the changes in various nitrogen components over time. Wheat plants were also grown for 30 days to evaluate the growth potential of plasma-treated soil, and accordingly their germination characteristics were analysed. The results indicated that ACP-DBD plasma treatment enhanced plant-available nitrogen species (NO₃⁻-N, NO₂⁻-N, and NH₄⁺-N) in the investigated soil under the specific experimental conditions highlighting its potential for modifying soil nitrogen chemistry for future soil fertility and supporting sustainable agricultural productivity.

常压冷等离子体富集土壤氮对高等小麦生长的影响

本研究探讨了常压冷等离子体介质阻挡放电（ACP-DBD）反应器的应用，通过增加亚硝酸盐、硝酸盐和铵的浓度来提高土壤肥力。ACP-DBD系统由双极脉冲电源供电，通过调节施加电压、频率和处理时间进行优化，确定了最佳等离子体条件为10 kV和20 kHz。用光学发射光谱（OES）分析了反应物质。此外，该研究还调查了反应器的电气特性和温度波动，为其运行性能和效率提供了见解。优化后的ACP-DBD处理（10 kV/20 kHz, 15 min）显著提高了土壤中氮的种类，NO₃-N浓度从678.87增加到1858 mg/kg， NO₂-N浓度从0.59增加到2.06 mg/kg， NH₄-N浓度从1.46增加到11.64µg/kg。为了评估ACP-DBD处理的影响，分析了土壤的关键特性，包括pH值、电导率（EC）、含水量、容重和总孔隙度。并采用x射线荧光（XRF）和ICP-MS分析进行多元素成分评价。结果表明，等离子体处理影响了土壤中各种元素的浓度。此外，等离子体处理后的土壤保存30天，以监测各种氮成分随时间的变化。小麦植株生长30 d，评价等离子体处理土壤的生长潜力，并分析其萌发特性。结果表明，在特定的实验条件下，ACP-DBD等离子体处理增强了被调查土壤中的植物有效氮⁺（NO₃⁻-N、NO₂⁻-N和NH₄⁺-N），突出了其改变土壤氮化学的潜力，有助于未来土壤肥力和支持可持续农业生产力。图形抽象

期刊介绍： Publishing original papers on fundamental and applied research in plasma chemistry and plasma processing, the scope of this journal includes processing plasmas ranging from non-thermal plasmas to thermal plasmas, and fundamental plasma studies as well as studies of specific plasma applications. Such applications include but are not limited to plasma catalysis, environmental processing including treatment of liquids and gases, biological applications of plasmas including plasma medicine and agriculture, surface modification and deposition, powder and nanostructure synthesis, energy applications including plasma combustion and reforming, resource recovery, coupling of plasmas and electrochemistry, and plasma etching. Studies of chemical kinetics in plasmas, and the interactions of plasmas with surfaces are also solicited. It is essential that submissions include substantial consideration of the role of the plasma, for example, the relevant plasma chemistry, plasma physics or plasma–surface interactions; manuscripts that consider solely the properties of materials or substances processed using a plasma are not within the journal’s scope.
