Pot Sampling - Day Four

Today was the final day of sampling. We had 7 more pots to harvest. This meant more digging out of the little meshes and more washing of roots. The difference between these pots and the ones we harvested on day two because these barley plants do not grow root hairs. The inside of the pots look very similar because the root hairs are very tiny and you need a microscope to see them properly.

Laurie used a penetrometer to measure the strength of the soil in the pot. It's smaller than the one they used in the field.

This is the end of our work in Dundee and we celebrated by eating an ice cream. Tomorrow we head back to Southampton.
