Noninvasive three‐ and four‐dimensional X‐ray imaging approaches have proved to be valuable analysis tools for vadose zone research. One of the main bottlenecks for applying X‐ray imaging to data sets with a large number of soil samples is the relatively large amount of time and expertise needed to extract quantitative data from the respective images. SoilJ is a plugin for the free and open imaging software ImageJ that aims at automating the corresponding processing steps for cylindrical soil columns. It includes modules for automatic column outline recognition, correction of image intensity bias, image segmentation, extraction of particulate organic matter and roots, soil surface top...
