After field application of pesticides, soil may be sampled at several depths to ascertain persistance and movement in the profile. A simple, inexpensive device was designed to facilitate manual sampling and preserve sample integrity for sandy or loose surface soil. When samples are obtained from several depths, the guard prevents loose soil on the surface from sloughing into the hole and contaminating samples from subsequent depths.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
