Gouge and Peat Augers

Gouge auger set

Different types of hand augers are used for peaty soils. The most popular are the gouge augers; long, semi cylindrical chambers which are pushed into the soil, twisted and recovered to display a full and virtually undisturbed profile of your peaty soil. Gouge augers are available in three diameters and three lengths. In common with all hand augers they are available as single models or as two parts which can take extension rods.

Peat sampler set

The other popular sampler is the peat auger; sometimes called a “Russian” sampler or corer. These samplers are inserted in the soil in a closed position down to the desired sampling level and then twisted so that the sample is trapped in the chamber.


Vrijwit Auger

The Vrijwit auger is a stainless steel wedge shaped sampler particularly suitable for taking undisturbed samples from clay, loamy sand and soil that contains a lot of un-decayed material. It is also extremely suitable for taking samples from small, shallow waterways or banks in which a lot of roots and dead organic material is present.

Rectangular samples collected with the Vrijwit auger can be accurately described with the stratification and composition of the soil and the size of the retrieved sample enables sub-sampling for volatiles.

Peat Probes

To determine the depth of peat the Utility Probe is light, strong and is available with 92cm extension rods.


The right equipment for the job

Whether you classify sediment as a weak soil or all soils as sediment what's certain is to collect samples when the soil is wet, soft and non-cohesive, will be challenging and retention can be difficult so the sample will need to be enclosed or captured in a liner. Poor samples lead to errors in analysis and inaccurate conclusions.

Sediments present special challenges and using the right equipment will save you time, money and mistakes. Sediments are weak and non cohesive so retention of the sample is often difficult which means that it must be enclosed or captured in a liner as incorrect samples lead to errors in analysis and therefore the conclusions. Peat soils can often be captured in gouge augers or a peat or Russian corer but where the sediments are very sloppy and especially when sampling below the water table different equipment is required.

Mostly these samples are taken with a piston sampler such as the Multisampler, Beeker sampler or Stitz corer.They will be inserted in the material in a closed position and only opened at the start of the desired horizon. These samplers are also very useful in capturing the water/sediment interface which is often of immense importance to researchers to test if the contaminant is contained or occurs in both materials. Mostly, the use of these piston type samplers produce a virtually undisturbed sample but for rough and ready work Van Veen type samplers can also be used.
