climate change, fertilizers, nitrous oxideAbstract
Guaranteeing global food security and mitigating global warming requires optimizing agrifood productivity and reducing emissions of greenhouse gases, such as nitrous oxide (N2O), which has a global warming potential 300 times greater than that of carbon dioxide (CO2). In this context, it was proposed to demonstrate that the appropriate application of synthetic fertilizers enables environmentally responsible food production and to identify the impact of reducing nitrous oxide through strategies for the efficient use of synthetic fertilizers. The ex post facto design was applied along with a review of the literature in journals indexed in Scopus in 2023 and 2024; various strategies for applying synthetic fertilizers were identified, and the results show that it is necessary to reduce synthetic fertilizers and add biochar or other minerals that maximize the use of nitrogen by plants and minimize environmental emissions; the application of Student’s t for 15 studies on wheat, rice, and maize crops revealed with a significance of 1% (p= 0) that the strategies shown on the use of nitrogen fertilizers in crops reduce N₂O emissions. It is concluded that the appropriate application of synthetic fertilizers significantly enables environmentally responsible food production.
