Measurement of rates of atmospheric sulfate dry deposition to vegetation is necessary to assess biophysical relationships. However, micrometeorological measurement techniques have stringent site and equipment requirements and direct estimation techniques have procedural and contamination difficulties. This paper describes the development and testing of a leaf washing technique to directly measure the rate of sulfate dry deposition to hardwood forest vegetation. The leaf washing technique was developed by comparing the rate of removal of sulfur dry deposited to leaf surfaces with the rate and extent of leaching from the internal sulfur pool.
