262 Tomography and Imaging for Soil-Water-Root Processes: III

Oral Session
S01 Soil Physics This symposium will provide an update of tomography and imaging methods for evaluation of soils. Specific methods to be discussed include x-ray computed tomography, synchrotron microtomography, neutron imaging, geophysical imaging tools, and other tomography techniques for evaluating soil and root systems. These presentations will provide a unique collection of topics exploring applications of imaging and tomography systems for soil science. Several new procedures and applications have been developed over the past two decades which will be discussed.
