Vertical and horizontal patterns of pine root water and nitrogen uptake

Summary

This project uses isotopic labels to describe the depth and breadth of root activity. The work involves adding the label to plots, monitoring the passage of the water label through the stems, monitoring the accumulation of nitrogen in the canopy, and measuring the deuterium labelling of stem wood in the trees around the plots. The understory vegetation and any mushrooms will also be described, as will patterns of soil water isotopic labelling.
