Profile sampler

05.08

The profile auger is used to take a large and virtually undisturbed sample to a depth of 40 centimetres (10 centimetres wide and 5 centimetres in diameter). All roots up to 2 centimetres in diameter are included in the sample.

  • Soil sampling above groundwater table
  • Undisturbed sampling
  • Suitable for almost all soils
  • Soil profile description and classification
  • Compaction and integration of the various soil layers does not occur

Description

With the profile drill, a large and virtually undisturbed sample can be taken to a depth of approximately 40 centimetres (10 centimetres wide and 5 centimetres across). Because the sample is virtually undisturbed, you can sample layers separately. All roots, up to a cross-section of 2 centimetres, are included in the sample.

It allows for simple determination of the volume/weight of various differing layers. You can quickly and accurately observe the quantity and distribution of root growth. 

When sampling, the two U-shaped chutes are pushed into the ground alternately until the desired depth is reached, after which one side of the shaft is pulled up sharply and the other pushed down, thus clamping the profile. The profile sampler may now be extracted and opened to sample or describe the profile. Placing the sample back, to reduce the disturbance of the location to be researched to a minimum, can be done easily.

Applications

  • Soil profile description and classification
  • Soil sampling above groundwater table
  • Undisturbed sampling
  • Soil texture research
  • Root zone sampling
  • Root growth research
  • Ecological/biological research of a strip layer in the forest
  • Soil surveying
  • Creating monoliths without the necessity of digging a profile pit
