Improved Performance of Zero-Tension Lysimeters1
- R. Radulovich and
- P. Sollins2
Published collection efficiencies (volume of water collected divided by percolating volume calculated from a water balance) of zero-tension lysimeters are <10%, suggesting that samples collected by such lysimeters may not be representative of the water percolating downward. By increasing catchment area to 2500 cm2, and by pushing the lysimeter rim upward into the soil, collection efficiency was increased to 36% under grass and 17% under forest; failure rate (proportion of lysimeters yielding <50 mL) was decreased from 60 to 6% under grass and to 23% under forest.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
