生物量-N 与酸解的氨基酸态氮及未知态氮都有显著相关性。
The amount of soil biomass-N was markedly increased by the application of fertilizers.
继续增加施氮量，土壤微生物量氮含量增加，但土壤中残留大量硝态氮，易淋溶损失。
Applying more nitrogen would increase the content of soil microbial biomass nitrogen, but might result in large amount of nitrate residue in soil and suspected to leaching loss.
