1 INTRODUCTION Nitrous oxide (N2O) is one of the powerful and long-lived greenhouse gases (GHG). Its atmospheric concentration has increased by approximately 24.8% from pre-industrial levels to 2023 (Lan et al., 2024). Among all known N2O surface emission sources, agricultural soil accounts for around 50% of the anthropogenic N2O emissions (Shcherbak et al., 2014; Tian et al., 2020).

AbstractFarmed soils contribute substantially to global warming by emitting N2O (ref. 1), and mitigation has proved difficult2. Several microbial nitrogen transformations produce N2O, but the only biological sink for N2O is the enzyme NosZ, catalysing the reduction of N2O to N2 (ref. 3). Although strengthening the NosZ activity in soils would reduce N2O emissions, such bioengineering of the soil microbiota is considered challenging4,5.

The industrial emissions of nitrous oxide, a potent greenhouse gas and stratospheric ozone-depleting substance, have increased since 2010. However, untapped abatement potential for industrial emissions currently exists through low-cost technologies. Nitrous oxide (N2O), the third most important anthropogenic greenhouse gas, contributed 6% of total effective radiative forcing for the 1960–2019 period1.
