abstract
Because the widely used ceramic cups are reported to release, adsorb, and filter dissolved nutrients from soil solution samples, inert cups made of poly(tetrafluoroethene) (PTFE) are frequently proposed as a more reliable alternative. A ceramic and a PTFE/quartz cup were compared with each other in this laboratory study. The PTFE/quartz cup was the most suited for pH measurements. Because only the ceramic cup samples both ammonium and nitrate in a satisfactory way, this cup type is recommended for nitrogen (N) balance studies. In most cases, the ceramic cup also performed better in sampling cations [sodium (Na+), potassium (K+), calcium (Ca2+), magnesium (Mg2+)] than the PTFE/quartz cup. Both cup types seemed inadequate to sample soil solution for aluminum (Al3+) determinations. The ceramic cups released chloride (Cl-) at low ion concentrations, but sulfate (SO42-) concentrations remained almost unaltered in the sample as compared to the solution outside the cup. In contrast, Cl- and SO42- were retained by the PTFE/quartz cups. The overall conclusion of this study is that PTFE/quartz cups have no clear advantages over the more widely used ceramic cups for use in ecological studies dealing with dissolved inorganic ions in the soil solution.
