Digging and planning the ground for 12 root towers at Højbakkegård in Denmark
Root towers provide semi-natural study conditions
At Højbakkegård 25 km west of Copenhagen there are 12 root towers placed above ground. Each tower is 4 meters tall and plants are able to grow in the deep containers with transparent walls allowing direct root observation. The subsoil layers of the system is prepared so that there is easy access and application of tracers or sampling for analysis of soil, soil water, roots and other soil biology is possible.
The conditions will be unnatural in many ways, but they will allow cheaper and more detailed studies, and thereby be ideal for testing of methods, species and other questions. They are also ideal for illustration and publicity purposes, as roots will be easily visible in such systems.
