An Inexpensive Method for the Study of Root Growth in Containers of Solid Media1

Abstract
A method was developed for observing root growth utilizing polyvinyl chloride pipe with a removable observation window. The simplicity of the equipment and its ability to permit application of soil compactive forces made it ideal for studies on the effects of soil compaction on root growth. It has also proven to be a valuable teaching aid in horticulture laboratory demonstrations.
