Soil biogeochemical variables collected on the Arctic Long Term Ecological Research (ARC LTER) experimental plots in moist acidic and dry heath tundra, Arctic LTER, Toolik Field Station, Alaska 2017.

**Note: Versions 1 and 2 had the wrong data files.**

Soil nutrients (total Carbon and Nitrogen, inorganic nutrients (ammonium ion (NH4), nitrate anion (NO3-), phosphate anion (PO43-)); organic nutrients (extractable organic carbon (EOC), extractable total nitrogen (ETN), extractable organic phosphorus (EOP)), microbial biomass, and extracellular enzyme activity on soils sampled from the Arctic LTER Dry Heath (organic soils only) and Moist Acidic Tundra (organic and mineral soils) herbivore exclosures and control plots at Toolik Lake, AK in July 2017.

**注：版本1和版本2包含错误的数据文件。**

本数据集涵盖2017年7月在阿拉斯加州Toolik湖北极长期生态研究站（Arctic LTER）干苔原（仅有机土壤）及湿润酸性苔原（有机土壤与矿质土壤）的食草动物排除区（herbivore exclosures）与对照样地（control plots）采集土壤的各项指标，包括土壤养分（总碳与总氮、无机养分（铵离子（NH4）、硝酸根阴离子（NO3-）、磷酸根阴离子（PO43-））、有机养分（可提取有机碳（EOC）、可提取总氮（ETN）、可提取有机磷（EOP）））、微生物生物量（microbial biomass）及胞外酶活性（extracellular enzyme activity）。
