- the soil N content 土壤含氮量
- The result showed that the soil available N content of the vineyard a low and in grade 5 while that was in grade 3 in the kaleyard. 结果显示：东丽区葡萄园的速效氮含量较低，处于5级；
- N mineralization, extractable mineral N or the use of a non-fixing legume or grass to measure available N supply are useful tools to account for the soil N variable. 氮矿化、可浸提的矿质氮以及利用不固氮的豆类植物或禾本科来测量氮供应均是解释土壤N变量的有用手段。
