Taking soil samples can be made easier by lubrication of the probe, especially for wet soils and
high clay content soils. The soil can stick to the probe and stop the soil from being released from
the probe or make it difficult for the probe to take up soil in the first place. The result of which is
a poor sample being taken that does not represent the intended depth from compressing the soil
down instead of sliding up into the probe. Research studies performed at different universities
have shown no significant effect on soil sample data for macro and micronutrients from
lubricating soil probes with WD-40 or cooking spray. Additional investigation performed by
Midwest Labs agrees with this.
