Field sampling (Fig. 15)

• Clear and prepare the soil surface to make sure representative samples can be taken.

• Place 5 sample rings on the soil surface.

• Place the sample tool over the sample ring.

• Drive the ring fully into the soil by hammering the sample tool.

• Excavate the sample by spade or trowel.

• Remove the surplus soil to ca 2-5 mm of the sample ring both sides.

• Cover the ring with transport caps preventing to dry out and compressing the soil sample.

• Register the ring number and sample details.
