Plant root distributions are thought to determine plant growth and coexistence, but are notoriously difficult to measure. This dataset describes the concentration of deuterium oxide in plant tissues in plots where deuterium oxide was injected to target depths.

One mL of 70% D2O, followed by 2mL of tap water were injected in a 15 cm by 15 cm grid to target depths in circular plots with a 1.5 m radius. Two days later non-transpiring plant tissues were collected and plant water was extracted using cryogenic distillation. Extracted water samples were analyzed for 18O and D concentrations on a Picarro cavity ring-down spectrometer.
