The neodymium isotope ratios (143Nd/144Nd) and rare earth element compositions of eight plant species in a well-studied Ca-depleted research forest (the Strengbach catchment) were measured. The 143Nd/144Nd ratios distributed between the higher ratio of apatite and the lower ratio of plagioclase. The...
