Plant and root biomass, nitrogen, carbon, and phosphorus concentrations in a mesic acidic tussock tundra experimental site established in 1981(MAT81) and harvested in 2015, Arctic LTER, Toolik Lake, Alaska.

Plant and root biomass, nitrogen, carbon, and phosphorus were measured in 2015 in the Arctic LTER tussock tundra experimental site (MAT81). This site was established in 1981 and has been harvested in previous years (see Shaver and Chapin Ecological Monographs, 61(1), 1991, pp.1-31, https://doi.org/10.2307/1942997). Data tables include the biomass for each harvested quadrat and block summaries for percent carbon, nitrogen, and phosphorus for control and fertilized plots from the original 4-block design. New control plots, established in 2015, are in a separate data table and include biomass, percent carbon, nitrogen, and phosphorus for each quadrat.

2015年，研究人员于北极LTER（Long-Term Ecological Research）丛苔原实验样地（MAT81）测定了植物与根系生物量、氮、碳及磷含量。该样地始建于1981年，此前历年均开展过收割采样工作（详见Shaver与Chapin发表于《生态专论》（Ecological Monographs）第61卷第1期，1991年，第1-31页，链接：https://doi.org/10.2307/1942997）。本次公开的数据表格涵盖各收割样方的生物量，以及基于原始4区组设计的对照组与施肥样地的碳、氮、磷质量占比的区组汇总数据。2015年新设的对照组样地单独归入一张数据表，其中包含各单样方的生物量及碳、氮、磷质量占比数据。
