Soil nitrate and ammonium: Fire X Nitrogen: Interactive Effects in a Prairie-Like Grassland

This experiment was established on top of E002 in field B. In the spring of 1992, 3 randomly chosen replicates of each nutrient treatment of experiment E002 were chosen to be burned each spring. For a description of these plots, see E002. For a list of treatments, see the treatment layouts in file trmte98.本实验以B地块的E002实验为基础开展。1992年春季起，我们选取E002实验中各养分处理的3个随机重复样地，设定每年春季对其实施焚烧处理。关于此类样地的详细说明，请参见E002实验文档。若需获取处理方案列表，请查阅文件trmte98中的处理布局内容。
