Vacuum Extractors to Assess Deep Percolation Losses and Chemical Constitutents of Soil Water1

H. R. Duke and H. R. Haise2

ABSTRACT

A vacuum extractor, consisting of a porous ceramic tube within a sheet-metal trough, has been developed to provide a quantitative measure of soil water lost by deep percolation and to provide a water sample for chemical analysis. Several of these extractors have been installed in the field and preliminary field performance is reported. Detailed laboratory evaluation is in progress.
