On the challenges of using field spectroscopy to measure the impact of soil type on leaf traits

Working with 24 chemical and physical leaf traits of six European tree species growing on strongly contrasting soil types (i.e. deep alluvium versus nearby shallow chalk), we asked whether variability in leaf traits is greater between tree species or soil type,
and whether field spectroscopy is effective at predicting intraspecific variation in leaf traits as well as interspecific differences.
