Abstract | For lysimeters used as arable land or unimproved grassland and having a controlled lower boundary condition, the solute concentrations in by-pass and leachate tanks were compared. While the by-pass bottles are only filled with lysimeter seepage, water is taken during watering periods from the leachate collection tank and pumped back into the lysimeter vessels. The solute concentrations measured in the by-pass bottles and in the leachate collection tanks differed significantly (different element patterns). Due to dilution effects (supply of additional water), the concentrations measured in the leachate collection tanks tended to be lower. Statements on seepage-related solute discharge should only be derived from lysimeters with controlled lower boundary based on solute concentrations measured in by-pass bottles. |
