... the correct procedure for
collecting soil/grass/loose dirt samples? How to prepare them, contain
them, preserve them? ...
The main concern here is introducing contaminants that would give
misleading test results.
...I would think
that the biggest concern would be microbe contamination from the
scoop. Also would Ziplock Freezer Bags be a good container? Or maybe
Tupperware Containers or the like? How should the container be prepared?
