Soil and understory CO2 respiration, CH4, and N2O fluxes, tree biomass and litter, and soil carbon stock after a long-term N fertilization of a Scots pine forest in Finland

Data of forest soil respiration, soil and undestory respiration, CH4, and N2O fluxes, soil temperature and volumetric water content (Data_Karstula_GHG_temp.swc.csv), forest biomass and litter (Data_Karstula_total_biomass_litter.csv, Data_Karstula_measured_litter_2021_2023.csv), and soil C stocks (Data_Karstula_soc.csv) from the boreal Scots pine forest site Karstula after a long-term N fertilization in Finland (62°54'43.343"N; 24°34'16.021"E). The dataset is used for the publication "Tupek et al. : Lower sensitivity of microbial respiration to soil moisture after long-term N fertilization increases soil carbon retention in a Scots pine forest. 2024".芬兰卡尔斯特乌拉（Karstula）寒带欧洲赤松（Scots pine）林样地经芬兰境内长期氮施肥处理后采集的相关数据，涵盖土壤呼吸（soil respiration）、土壤与林下植被呼吸、甲烷（CH4）与氧化亚氮（N2O）通量、土壤温度及体积含水量（volumetric water content），对应数据文件为Data_Karstula_GHG_temp.swc.csv；森林生物量与凋落物相关数据对应文件为Data_Karstula_total_biomass_litter.csv、Data_Karstula_measured_litter_2021_2023.csv；土壤碳储量（soil C stocks）相关数据对应文件为Data_Karstula_soc.csv。该样地地理坐标为62°54'43.343"N; 24°34'16.021"E。 本数据集已应用于2024年发表的论文《Tupek等：长期氮施肥后微生物呼吸对土壤湿度的敏感性降低可提升欧洲赤松林土壤碳固持能力》（Tupek et al. : Lower sensitivity of microbial respiration to soil moisture after long-term N fertilization increases soil carbon retention in a Scots pine forest. 2024）。
