Movement and persistence of 1,2-dibrotno-3-chloropropane (DBCP) in a Coastal Plain soil containing a sandy plow-pan were enhanced in each of 2 years by subsoiling, increased depth of application, and increased rate of application. DBCP was extracted from the soil with hexane and analyzed by gas chromatography. Subsoiling at a 35-cm depth gave the greatest increase in lateral movement and downward penetration of DBCP in 1975 (a wet year), but bad less effect in 1976 (a dry year). An increased application rate (10 kg/ha vs. 13.5) improved coverage moderately in 1975 by increasing lateral movement, but had little effect in 1976. Increased application depth (18 vs. 35 cm) improved coverage in both years though more in 1976. Deep placement extended DBCP retention time. Rainfall in 1975 probably decreased the number and size of air-filled pores, slowing loss of DBCP to the atmosphere. Because of reduced porosity, the plow-pan was impervious to the passage of DBCP unless disrupted by subsoiling.
