Earthworm Affect On Chemical Leaching.

Many studies have been conducted on the effects of earthworms on the movement of chemicals through the soil.  However, these studies were mostly focused on the effects of earthworms in a field setting and did not focus on the underlying mechanism.  Our study, consisted of a laboratory monolith study, to determine soil physical property parameters, and using these to calibration a model.  Model simulations were then run using the laboratory data, as well as field measurement to determine the potential for the effect of earthworms on the dispersion of a chemical added to the soil.  The result of the study will be discussed.
