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

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 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

本数据集涵盖的土壤测定指标包括：土壤全量养分（总碳（total Carbon）、总氮（total Nitrogen））；无机养分（铵离子（ammonium ion, NH4+）、硝酸根离子（nitrate anion, NO3-）、磷酸根离子（phosphate anion, PO4^3-））；有机养分（可提取有机碳（extractable organic carbon, EOC）、可提取总氮（extractable total nitrogen, ETN）、可提取有机磷（extractable organic phosphorus, EOP））、土壤微生物生物量以及胞外酶活性。供试土壤采自美国阿拉斯加州图利克湖区域长期生态研究网络（Long Term Ecological Research, LTER）的干旱石楠生境（仅采集有机土壤）与湿润酸性苔原生境（采集有机及矿质土壤）的草食动物排除样地和对照样地，采样时间为2017年7月。
