The potential of organic fertilizers and water management to reduce N2O emissions in Mediterranean climate cropping systems. A review

► Information about N2O emissions from Mediterranean crops was analyzed. ► Direct N2O fluxes are generally lower for organic than for synthetic fertilizers. ► Irrigation highly increased emissions, but the increase was lower with drip irrigation. ► The most promising practices, constraints and research gaps have been summarized. ► Further research is needed to fully understand and develop N2O mitigation potential.
