Field Operations

Soil Coring

Once you have competed probing, remove NIR/EC force probe as outlined in Section 6.

- Install drive coupler to rotating head by means of drive retainer (Figure 10)

- Install PETG liner onto cutting shoe and thread into sampling tube (Figure 11)

- Install sampling tube into drive coupler and push into soil.

Use slow and steady insertion speed and minimal

rotation to push core sampler into the soil. A brief

rotation at bottom of stroke will snap off the core in

tight clay, giving you a fuller core as you retract.

(Figure 12) Excessive rotation may affect the

condition of your cores.
