Gouge Auger Set - for Stepwise Sampling

The gouge auger set for stepwise sampling is used for profile research (nitrate research) in soils with a somewhat higher penetration resistance. The set contains three two-piece gouge augers with different diameters.
Environmental and archaeological soil research
Soil sampling above groundwater table
Gouges 40, 30 and 20 mm of 30 cm net length
Start large and finish narrow to limit pulling up force
For soils with a somewhat higher penetration resistance
 
The set consists of three two-piece gouge augers with different diameters. By first taking a sample with the gouge with the largest diameter and subsequently with gouges having smaller diameters, cross-contamination among the samples is avoided. The gouges have a diameter of 40, 30 and 20 millimetres with a net length of 30 centimetres
The gouge augers can be pushed into the soil, or hammered with an impact absorbing hammer. Because of the short operational length and the decreasing diameters the set is most suitable for profile research (nitrate research) in soils with a somewhat higher penetration resistance. For example, to sample the top of agricultural land to a depth of 90 centimetres.
