Notizen: Abstract Twelve profiles were obtained from a 2 ha field, 6 from where Cu had been applied for 15 yr and 6 from areas not fertilized with Cu. The 30 to 50 cm layers in the profiles in both areas contained similar amounts of Cu indicating a lack of vertical migration of the fertilizer metal under field conditions. A buried layer of humified material was found mostly between 50 and 60 cm depth. Of the mineral elements which enriched this layer during degradation and humification, perhaps a few thousand years ago, Cu, Pb and Mn were apparently retained more than Ca, Fe, Ni, Al, Mg, Zn and K.
