Soil moisture determinations by Electrical Resistivity (ERT) Experiment at the Kellogg Biological Station, Hickory Corners, MI (2009)

Dataset Abstract Large-scale conversion of croplands to perennial biofuel crops could substantially impact regional water, nutrient, and C cycles due to the longer growing seasons and differences in rooting systems compared with most annual crops. However, these differences in crop water use are not well known due to the limited tools available to nondestructively study the spatiotemporal patterns of root water uptake in situ at field scales. Geophysical imaging tools such as electrical resistivity (ER) reveal changes in water content in the soil profile.

数据集摘要
大规模将农田转为多年生生物燃料作物，由于相较于多数一年生作物生育期更长、根系系统存在差异，可能会对区域水、养分及碳循环产生显著影响。然而，由于缺乏可在田间尺度原位无损研究根系水分吸收时空格局的工具，学界对作物水分利用的这类差异尚缺乏充分认知。地球物理成像工具（如电阻率成像（electrical resistivity, ER））可揭示土壤剖面的水分含量变化。
