Abstract

Excessive nitrogen use in high-input agriculture has led to nitrogen loss, methane emissions, and soil degradation in rice paddies. While high soil quality can enhance rice yields and reduce environmental impacts, the level of improvement needed to ensure sustainable rice production in China remains unclear.
