The Gene Transfer Study was a long-term experiment to examine the effects of different 2,4-D application rates on the 2,4-D degrading microbial population and to test hypotheses about the rate of genetic change in soil microbes. The experiment was established at the LTER Main Site in 1988 and retired in 2010.
Treatment plots were 12 x 30′ (3.7 x 9.1 m) and replicated in each of 2 randomized blocks. See the plot map for treatment codes and application rates. GAP = Good Agricultural Practice (for broadleaf weed control); 1X = 1 mg/kg.
