Above ground plant biomass a moist acidic tussock tundra experimental site, 1984, Acric LTER, Toolik Lake, Alaska.

Above ground plant biomass was measured in a tussock tundra experimental site. The plots were set up in 1981 and have been harvested in previous years (See Shaver and Chapin Ecological Monographs, 61(1), 1991 pp.1-31.) This file is the July 26-27, 1984 harvest of the controls and nitrogen + phosphorus treatments.在一处丛粒苔原（tussock tundra）实验样地中开展了植物地上生物量测定工作。该实验样地于1981年设立，此前历年均已进行过收割采样（详见Shaver与Chapin发表于《生态学专论（Ecological Monographs）》1991年第61卷第1期，第1-31页的研究）。本数据集对应1984年7月26日至27日完成的对照组与氮磷联合处理组的收割采样工作。
