There was an increase in penetrometer resistance during the Festival period, but this increase occurred outside, as well as inside, the area occupied by the Festival.
After vertical insertions from the soil surface with the `Rimik' penetrometer, the soil was gently scraped aside to expose the soil at a depth of 90 mm (furrows) or 190 mm (ridges) for the other measurements.
During an experiment at the USDA-ARS National Soil Dynamics Laboratory (NSDL) in Auburn, Alabama, it took more than three days to obtain 800 sets of force-depth data with a tractor-mounted soil cone penetrometer. Researchers then decided to design and build a unit with multiple probes that take several readings at one time across a row.
