Toward Green Liquid Nitrogen Fertilizer Synthesis: Plasma‐Driven Nitrogen Oxidation and Partial Electrocatalytic Reduction

fertilizer significantly improves plant growth, with stem length and leaf length increasing by 91.26% and 54.72%, respectively. Cost estimation reveals that 44.22% of the production cost is attributed to electricity consumption, underscoring the potential for optimization with renewable energy integration. Overall, the study provides new insight for the sustainable production and in-place utilization of liquid nitrogen fertilizers which may advance sustainable agriculture.
