We discussed in this article the main mechanisms by which soil engineers impact soil structure and
proposed to classify soil engineers with respect to their capacity to produce biostructures and modify
them. We underlined the lack of studies considering biostructure dynamics and presented recent
techniques in this purpose. We discussed why soil engineering concept is mainly considered by soil
ecologists and call for a better collaboration between soil ecologists and soil physicists. Finally, we
summarized main challenges and questions that need to be answered to integrate soil engineers
activities in soil structure studies.
