A Washington State University scientist is using soil windows — rhizotrons — to track root growth and connect it to other factors such as soil temperature and weather. Bernardita Sallato, a WSU tree fruit extension specialist in Prosser, Washington, built the rhizotrons, acrylic panes slid vertically into square soil pits, to give her windows through which to watch root zone development.
