ABSTRACT:
An apparatus automatically removes soil samples at intervals over a field of interest. The apparatus comprises a sampling assembly that rotates on a track. The probe of the sampler assembly is extended through the track and into the ground, then retracted on each revolution of the track. The sampler assembly is hinged and guided along a track in order to minimize soil compaction as the probe rotates around the rear wheel of the apparatus. Soil is ejected by means of a “rumble path” along the top of the track. The soil samples are pneumatically transferred to a bagging assembly located in the tractor pulling the apparatus.
