In our model the drone (shown propped up on cups) flies above the forest (made of paper and block trees). The tensiometer hangs from the drone, collecting soil samples. In reality the drone would fly closer to the ground and intermittently collect soil samples. Photo courtesy of the Juniata College SPS reporters.
