Abstract
Abstract There is disclosed a soil sampling device having a sampling unit arranged on a disc which can be rotated around a quasi-horizontal axle on the arm of a frame attached to a vehicle. Also on the arm is a sample removing unit which removes the sample from the sampling unit and places it in a sample collection box. The invention provides a means to carry out soil sampling quickly, reproducibly and automatically and obtain an authentic picture of the properties of the investigated soil.
