Soluble chemicals applied to soils have been identified as major sources of surface and groundwater contamination. This research examined the application of a small dc electrical input to attract and retain nitrates in the root zone of drip irrigated barley in small lysimeter trials. Nitrate content near the anode was higher and pH lower, as desired, during a portion of the test. However, the electrical input seemed to have little effect on nitrate distribution at other times, perhaps due to careful management of water and nitrate inputs. These results indicate a potential benefit of an electrical input to the control of nitrate transport in soil.
