Basic components of the device disclosed herein are a sample tube, driver sleeve, driver cap and driver head. The sample tube is a pipe which is split lengthwise into two semicircular sections. In assembled position, i.e. during the soil collecting function, the split sample tube is a unitary tube which fits inside a larger pipe that defines the driver sleeve. The driver cap is an internally threaded cup-shaped member with an upstanding solid stem thereon and a crosswise handle. The cap is secured to the upper end of the driver sleeve by external threads on the sleeve. The driver head is a one-piece member comprising a solid block, a hollow stem which fits over the solid stem of the driver cap, and loop-type handles. The loop handles enable the driver head to be lifted up and down, so that the driver stem can hammer down against the cap and thereby drive the sleeve and sample tube into the earth.
