Nitrogen mineralization was determined on Arctic LTERToolik and Sag River tussock tundra using the buried bag method, Toolik Field Station, Alaska, Arctic LTER 1989-2013.

Nitrogen mineralization was determined on LTER and Sag River tussock tundra using the buried bag method. Yearly bags have been deployed every August since 1990.

本研究采用埋袋法（buried bag method），对LTER站点与萨格河丛苔原（Sag River tussock tundra）的氮矿化（Nitrogen mineralization）水平进行了测定。自1990年起，每年8月均会布设年度埋袋样本。
