The paper shows that nutrient enrichment, especially with nitrogen and phosphorus, reduces C4 plant cover in grasslands, disrupting climate-driven C3-C4 balance globally.

This study shows that leaf photosynthetic responses to elevated CO2 are driven by nitrogen demand, while whole-plant responses are regulated by nitrogen supply, using soybean plants under varied CO2 and nitrogen conditions.
