Aligning Nitrogen Form With Rice Preference Through Enhanced‐Efficiency Fertilizers Raises Yield and Cuts Emissions

Rice sustains nearly half of the global population, yet its nitrogen (N) use efficiency remains low, undermining both food security and environmental integrity. Rice predominantly absorbs ammonium (NH₄ ⁺), which is readily nitrified and lost through irrigation and drainage, posing a persistent management challenge. Integrating 1756 paired field observations and global modelling, we show that using enhanced-efficiency fertilizers to maintain soil NH₄ ⁺
