Abstract

An efficient Ceramic-Cup Water Collection Instrument (CCWCI, "quickie") is described. Soil water collection from ceramic-cup samplers may require compositing by equal volume from distantly spaced samplers, or simultaneous water collection spaced samplers, or simultaneous water collection from closely spaced samplers without compositing. All collection must be done with minimal opportunity for sample contamination. the CCWCI combines these and other soil water collection needs into a streamlined system that may be adapted to a variety of experimental designs and field conditions.
