“…Nitrate-based fertilizers also have environmental benefits that reduce ammonia volatilization [19]. As a result, the second route may be more suitable for on-site nitrogen fertilizer supply near various crops with high demand for nitrate nitrogen, such as wheat [20], tomato [21], and lettuce [22].…”

Plasma nitrogen fixation (PNF) has been emerging as a promising technology for greenhouse gas-free and renewable energy-based agriculture. Yet, most PNF studies seldom address practical application-specific issues. In this work, we present the development of a compact and automatic PNF system for on-site agricultural applications. The system utilized a gliding-arc discharge as the plasma source and employed a dual-loop design to generate NOx - from air and water under atmospheric conditions. Experimental results showed that the system with a dual-loop design performs well in terms of energy costs and production rates. Optimal operational parameters for the system were determined through experimentation, resulting in an energy cost of 13.9 MJ mol−1 and an energy efficiency of 16 g kWh−1 for NO3 - production, respectively. Moreover, the concentration of exhausted NOx was below the emission standards. Soilless lettuce cultivation experiments demonstrated that NOx - produced by the PNF system could serve as liquid nitrate nitrogen fertilizer. Overall, our work demonstrates the potential of the developed PNF system for on-site application in the production of green-leaf vegetables.
