Percent light penetration: Effect of N Addition on Vegetation With Mammalian Herbivory Initially on Disked Ground

This experiment is identical to E008 except the ground was disked thoroughly before the plots were laid out. From 1989-1994, plots with fertilizer treatment 1 were treated as complete controls (treatment 9), receiving no nutrients at all.本实验与E008实验完全一致，仅在样地布设前对地块实施了彻底翻耕。1989年至1994年间，原接受肥料处理1（fertilizer treatment 1）的样地被设为完全对照组（treatment 9），全程未施加任何营养物质。
