Repeat electrical resistivity tomography (ERT) measurements were conducted over four sites to capture the changing resistivity of the soil throughout the agricultural growing season, with measurements taken in Spring, Summer, and Autumn to detect the change between the construction, production, and post-harvest stages of the crop. Initial measurements were undertaken in April/May, Summer measurements in June/July, and final measurements in September 2021.

Provenance & quality

For each detailed survey location, a single 19m ERT transect was positioned with 96 electrodes spaced at 20cm intervals using a Campus Tigre system. The surveys were collected using a Wenner Array to collect data through the subsurface at sufficient vertical and horizontal resolutions. Each traverse collected approx. 660 apparent resistivity readings of the subsurface down to around 1m bgl. Data was collected in the field using ImagerPro2006.
