Soil Bulk Density on the Main Cropping System Experiment. at the Kellogg Biological Station, Hickory Corners, MI (1995 to 1996)

Dataset Abstract Soil bulk density is used to convert water content by weight to water content by volume and for calculating porosity and void ratio. Bulk density has an inverse relationship with soil structure and soil porosity. Bulk density data were collected using an excavation procedure found in the sampling protocols. Bulk density data are available from the forest sites in 1995 and all sites on the LTER Central Experiment in 1996. original data source http://lter.kbs.msu.edu/datasets/29

数据集摘要：土壤容重（soil bulk density）可用于将重量含水量转换为体积含水量，同时可用于计算土壤孔隙度与孔隙比。容重与土壤结构、土壤孔隙度呈负相关关系。本次数据集的容重数据采用采样规程中规定的挖掘法采集。1995年的森林样地与1996年长期生态研究（Long-Term Ecological Research, LTER）中心实验的全部样地均已公开其容重数据。原始数据来源：http://lter.kbs.msu.edu/datasets/29
