    Soil sampling tools

    There are two important requirements of a sampling tool.

    • Firstly, it must permit a uniform slice to be taken from the soil surface to a desired depth.
    • Secondly, it must collect the same volume of soil from each sample site.

    A soil auger is the best tool for obtaining soil samples, but a small shovel, trowel or a spade can work satisfactorily when used properly:

    You need a total bulked sample of about 400g/per field to send to the laboratory for full soil analysis.

    Step One: Dig out a spadeful or two of soil to a depth of 15-20cm, smooth off one vertical edge of the hole.

    Step Two: Take a slice of soil about 1cm thick with the spade. Using a trowel, the slice in half lengthwise while it is still on the spade and discard one half.

    Step Three: Remove any obvious contaminants, such as straw trash or stones. Put the remaining core from the spade in a bucket to be mixed with the other cores from the designated sampling area.

    Collecting a represenative sample

    For a repreenative sample follow the sampling grid guide below, avoid unusual spots, and try to obtain a well-balanced, representative sample from each point.
