Low-field magnetic resonance imaging of roots in intact clayey and silty soils

March 27, 2020
Author(s)
Mark S. Conradi, Stephen A. Altobelli, Dean O. Kuethe, Matthew S. Rosen, Neha Koonjoo, Bo Zhu, Karl Stupic, William L. Rooney, John E. Mullet, Brock Weers, G. Cody Bagnall, Haly Neely, Eiichi Fukushima, Cristine Morgan
The development of a robust method to non-invasively visualize root morphology in natural soils has been hampered by the opaque nature, chemical composition, and physical structure of soils. We describe here a novel technology—low field magnetic resonance
