1) losses
肥料氮
1.
Today because of low nitrogen utilization efficiency (NUE), high nitrogen-fertilizer application rates are often inevitable, leading to more and more losses of N-fertilizer.
在查阅了大量大田实验和15N追踪实验文献资料的基础上,对肥料氮损失量及主要损失途径进行了总结。
2) fate of fertilizer N
肥料氮去向
3) nitrogen balance
肥料氮平衡
4) Use efficiency of fertilizer nitrogen
肥料氮利用率
5) availability of nitrogen fertilizer
肥料氮有效性
6) Impact of fertilizer nitrogen on environment
肥料氮的环境影响
