Results of dry density and water content profile measurements.

Soil samples were obtained from the prepared test field by manual sampling with a metal tube. Samples were taken inside and outside several footprints, indicated by differing sampling depths, i.e., differing starting points of the top of the tube. Footprints are displayed schematically, for detailed information see Figure 11.

采用金属管手动采样的方式，从已准备就绪的试验田中获取土壤样本。在多处足迹的内外两侧采集样本，采样深度存在差异，具体体现为金属管顶端的起始位置各不相同。足迹以示意图形式呈现，详细信息请参见图11。
