SAMD00015723 410658 soil metagenome The high-throughput sequencing of 16S rRNA genes at the whole community level provides an almost unbiased profiling strategy for measuring characteristic changes in relative proportions of the microorganisms involved in certain functional processes, such as nitrification, in a complex system. There are 18 samples in the study.Each have three reduplicate.Two kinds of soil are involved in the study including forest soil(FS) and tea orchard soil(TS).The sample reflect the 16s rRNA gene diversity of forest soil and tea orchard soil in Zhejiang province of China.The soil samples were incubated in in soil microcosms for 8 weeks. Microcosm incubation was performed by adding 100.0 μg of urea-N g-1 d.w.s or sterilized water every week.
