Nutrient Management

In addition, one relevant study (by Raisin, et. al., 1998) considers the complexity of assessing the nutrient dynamics and hydrology of natural wetlands in the North East region of Victoria, and raises questions with respect to the use of such systems for the interception of diffuse source nutrient loads within rural catchments.
Another study by McKenzie-Smith, et. al., (1994) sampled five sites on the Ovens and King Rivers and analysed them for organochlorine pesticides residues. They found that the concentrations of DDE, DDT, and dieldrin residues were not different in different depositional areas, although increased proportions of DDD were found in sediments in the quiescent areas of the rivers. More than 70% of the dieldrin residues were found in the unsettled sediment fraction. Changes in flow during the storm event had a marked effect on the residues detected in the water column. DDT was present in largest amounts, which was most likely due to its association with non-filterable organic matter.
