- N use efficiency 氮肥利用率
- Fertilizer N not taken up by plant roots is subject to microbial immobilization and losses by denitrification, volatilization and leaching. 未被植物根系吸收的肥料氮会被生物固定和通过反硝化、挥发和淋失而损失。
- It is very important to increase fertilizer use efficiency (FUE) in China for its relatively low FUE and serious losses of nutrient. 尽管耕地面积只占世界耕地面积总量的7%25，但中国的化肥施用量却接近世界总量的1/3。
