Root biomass data: Nitrogen Addition and Dynamics of Recovery from Cessation of N Addition

This experiment was established on top of E002 in fields A and C. In the spring of 1992, 3 randomly chosen replicates of each nutrient treatment of experiment E002 were chosen to receive no more fertilizer. For a description of these plots, see E002. For a description of fertilizer added to E097, see file fertilization details. For a list of treatments, see the treatment layouts in file trmte97.

本实验以E002实验为基础，在A、C两块样地中开展。1992年春季，研究人员从E002实验各养分处理的重复实验单元中随机选取3组，对其不再施加肥料。有关本实验样地的详细说明，请参见E002实验文档。有关E097实验的肥料施加详情，请参阅文件fertilization details。若需查看处理组列表，请查阅文件trmte97中的处理布局方案。
