Augers, augering (soil) | SpringerLink

Augers, augering (soil) A common and relatively inexpensive method of obtaining disturbed soil samples is by auger borings. The depth to which auger borings may be taken is controlled by the depth to which the soil will not collapse and close an uncased hole or by the power limitations of the auger used ( Knill, 1978; Peters, 1978 ).
