Abstract The behavior of a mercurous‐mercuric chloride fungicide (Caloclor) added to turfgrass and bare soil was investigated. From 44 to 56% of the total Hg added to a turfgrass surface was lost in 57 days. Plant uptake and removal upon cutting did not account for these losses which were attributed to volatilization of metallic Hg formed in the turfgrass‐soil system. Where additions were made in the turfgrass root zone, loss was reduced and redistribution of Hg in the soil followed a pattern in qualitative agreement with metallic Hg formation and redistribution. Verification of volatilization from bare soil surfaces was made.
