| Research Abstract |
Tree root can accumulate 30% of individual tree biomass. Ground penetrating radar can detect roots non-destructively, but detection frequency of roots has not been elucidated. We conducted radar scanning in a Pinus thunbergii forest and compared radar detection images with vertical distribution of roots.
Detection frequency of Pinus roots that were larger than 1.0 cm in diameter was 54% and the methods using ground penetrating radar can estimate root biomass to be 68% of excavated roots. Root orientation can affect radar detection frequency in forest field.
