From the same field, saturated hydraulic conductivity (Ksat) measurements were made at 27 locations on a single occasion, at the same three depths. The location of sampling points (British National Grid) is given for all field measurements. The field was pasture and occasionally grazed by livestock, and part of the North Wyke Farm Platform, a highly instrumented and documented farm system. Additional data are available to complement this dataset using the URL in the related output.",
