The researchers in question opted to remove the macerated moss from the control group in order to guarantee that the results were accurate.

The experiment in question consists of:

  1. Placing volcanic rock samples into two glass containers
  2. Adding to one container the mixture of macerated moss and water
  3. The other container is the control, it receives only water
  4. The goal is to measure the release of minerals from the rocks.

When performing an experiment, the control group is of vital importance. The presence of a control group ensures the accuracy of an experiment.

Given that moss is grown on rocks and will erode the rock over time, the researchers opted to remove it from the control sample. Minerals present in the rock might mistakenly be measured as minerals released from the volcanic sample, thus making the results of the experiment inaccurate.
