樹木医による根系＆土壌改良の現場解説

This is a video series introducing the work of tree doctors, which is not often seen. One of the most important tasks of a tree doctor is "soil improvement." I hope that this video will convey the deep appeal of what they think and do when thinking about ways to protect trees. This time, we also had a special guest, Dr. Masamichi Takahashi, a fellow at the Forestry and Forest Products Research Institute, National Research and Development Agency, Forest Research and Management Organization.
