Aboveground plant and belowground stem biomass were measured in moist acidic and moist non-acidic tussock tundra experimental plots, Toolik Field Station, Alaska, Arctic LTER 2000.

Aboveground plant and belowground stem biomass were measured in moist acidic and moist non-acidic tussock tundra experimental plots. Treatments at the acidic site include control and nitrogen (N) plus phosphorus (P) amendments; treatments at the non-acidic site include N, P, N+P, greenhouse warming, and greenhouse+N+P.

本研究在湿润酸性与湿润非酸性丛苔原（tussock tundra）实验样地中测定了地上植物生物量与地下茎生物量。酸性样地的实验处理包括对照组以及氮（N）、磷（P）配施处理；非酸性样地的实验处理则涵盖单施氮（N）、单施磷（P）、氮磷配施、温室增温以及温室增温+氮磷配施五种处理方案。
