Nitrogen dioxide (NO2) impacts climate, air quality, soil nitrogen fixation, and crop production, yet its transboundary remain unclear. This study combines 15 global datasets to assess nitrogen’s on yields health. We use machine learning develop yield prediction models for major grain crops (maize, rice, soybean, wheat) affected by NO2. Our findings indicate stable fixation in China from 2015 2020, although overgrazing deforestation may cause declines. Increasing total content 0.62–2.1 g/kg can reduce NO2 10–30%. research indicates that the current agricultural environments (58.5–94.2%) have already exceeded concentration range tolerate, particularly regions near northern urban clusters. highlights need regional interventions, such as precision fertilizer management, enhance both yields. Scenario analysis suggests control boost maize rice a greener context, while increasing improves wheat soybean provides solution advancing sustainable agriculture linking cycle management with improved environmental sustainability.
