Describing the vertical root distribution of alpine plants with simple climate, soil and plant attributes
The vertical root distribution (VRD) in the soil remains unknown for most plant species, as studying root systems in different pedo-climatic settings is time-consuming and methodologically challenging. Yet, information on the VRD of different vegetation types is essential to understand better the bi...
