Soil Water Solutions

The appropriate sampling method depends on why you are sampling the soil. Soil Water Solutions sell two types of samplers and an ‘installer’ which is not intended to take a sample but to make a hole into which an instrument will be installed. The main difference is whether the soil is disturbed during sampling(mixed & broken up) or whether the sampler removes a portion of soil without disturbance. Mesurements of soil-water interaction generally must have undisturbed samples as they are affected by the structure of pores in the soil.

1. 50mm diameter soil auger- to obtain a disturbed soil sample from depths up to 2m (most commonly 0-1m). (We can supply larger augers but these can be obtained more cheaply from most hardware stores)

2. Tanner Sampler - to obtain undisturbed soil samples from surface, or near surface soils or the walls of a pit.

3. Tube sampler tips - to make tube samplers - these are usually used with a jack hammer or as an accessory for truck mounted hydraulic soil samplers. Samples are disturbed - but not as badly as with auger sampling

4. Instrument installers - these are ‘micro- augers’, not designed to take a soil sample (though they will), but are intended to make a small hole to install instruments.

50mm diameter soil auger

Supplied (usually) with a 1.2m handle (other sizes on application)

Price $80 (incl GST)

Tanner sampler - Kit comprises a plastic box with the sample guide, piston, rubber hammer, and 25 stainless steel or brass* sample rings in water proof containers. Kit price $1080 (incl GST)

Additional rings with containers are available $20 each (GST incl) spare containers only $5ea

This sampler complies with the standard that the sample ring area is < 5% of the sampled soil face to ensure that compaction of the sample is negligible.

* Brass rings are advised if samples are to be used for hydraulic conductivity as the stainless rings have a small seam which may ‘slot’ the sample. Stainless rings are tougher and more long lasting.

Tube sampler replacement tips. These are ‘Stace’ tube tips which can be fitted to readily available steel tubes so that when pushed into the soil (with a hammer or hydraulic ram), the soil sample inside the tube is smaller than the inner tube diameter (so comes out easily) and the hole made in the soil is larger than the outer tube diameter (so the tube can be removed easily) This is the easiest way to extract soil samples in quantity from depths up to 2m. The samples ARE disturbed - even if they don’t appear to be

	Micro auger instrument installers, these are small augers - 15mm diameter and upwards , custom designed to cut a precision hole in soil to install instruments. Price on application - an example is a 200mm auger with 0.5m shaft $75 GST incl
