Dr. Yasser Dergham lectures on tree root health and mycorrhiza

Terra-fit seminar on trees

The three-day Terra-fit seminar on trees was supported in the area of soil health / tree health by a lecture by Dr. Dergham from Humintech.

The previous days dealt with the Terra-fit patent as well as technical basics on root growth and soil science. Katharina Weltecke also gave a lecture on tree-related construction monitoring and the effects of construction on trees and soils. On the third day, Dr. Yasser Dergham reported to the participants on the growth of roots and permanent humus through humic acids. This also included help with tree stress, for example in the form of mycorrhiza.

We thank Terra fit for the opportunity to participate and the visitors for their interest.
