Long-term 15N balance after single-dose input of 15N-labeled NH4+ and NO3- in Tieshanping N-saturated subtropical forest

The long-term observation data of nitrogen saturated subtropical forest Tieshanping, including niteogen deposition, nitrogen leaching, ¹⁵N atom% and ¹⁵N recovery with once ¹⁵N tracer applied experiment, soil net mineralization rate in Tieshanping measured in October 2019, and the ratio of nitrogen leaching to total nitrogen input of relevant control experiments in Tieshanping and Europe.It can supplement researchers' cognition on the response of subtropical forests to nitrogen deposition, and provide help for the construction of biogeochemical knowledge network of forest ecosystem.

铁山坪氮饱和亚热带森林长期观测数据集，涵盖氮沉降、氮淋失、单次¹⁵N示踪试验中的¹⁵N原子百分比与¹⁵N回收率、2019年10月测定的铁山坪土壤净矿化速率，以及铁山坪与欧洲相关对照试验中氮淋失量与总氮输入量的比值。该数据集可补充研究者对亚热带森林响应氮沉降的认知，为森林生态系统生物地球化学知识网络的构建提供助力。
