ABSTRACT:
In abstract, a preferred embodiment of this invention is a soil sampler having a specially designed tip for easy penetration, a movable slot cleaner for cutting away surface soil that clings as the sample is taken, and depth markings for allowing accurate gauging of the samples. This invention also includes handles that are off-set 90.degree. from an open soil slot to allow the sampler to be placed horizontally on the ground with the slot upright without danger of tipping.
