Summary
By making use of a soil perfusion technique it has been shown that the detoxication of 2: 4-dichlorophenoxyacetic acid in garden loam is due almost entirely to the activity of microorganisms. Preliminary experiments suggest that the process does not involve oxidation. There are also indications that the decomposition products may include a root growth stimulant.
