Abstract Details

2017, Master of Science, Ohio State University, Environment and Natural Resources.
Soil quality has been defined by Doran and Parkin (1996) as the capacity of a soil to function within ecosystem boundaries to sustain biological productivity, maintain environmental quality, and promote plant and animal health. A multitude of physical, chemical, and biological parameters can be assessed to provide a comprehensive picture of soil quality. The overall objective of this study was to evaluate long term soil restoration and development of manufactured soil dredge blends by using these soil quality parameters. Chapter 1 assessed the soil quality of an urban site treated with biosolids or compost by comparing data collected over years of sampling after one initial application of the treatments. The results show that biosolids-based treatments leads to overall greater long-term soil quality than compost treatments. However, soil phosphorus in the biosolids-treated soils were of concern for runoff and surface water quality harm. Therefore, the study concludes that no treatment was the ideal amendment for overall improved soil quality, and that a blend of compost and biosolids together could be of interest in future research. In Chapter 2, soil quality parameters were used to assess dredge as a main ingredient in manufactured soil blends. With Ohio regulation changing how dredge must be disposed of, research into the beneficial reuse of soil-like dredge material is vital. Blends were designed by incorporating dredge materials, composts and clay then followed by a bioassay growing rye grass. Interestingly, the smaller size fraction dredge material, which is believed to be unsuitable for reuse, resulted in greater soil quality for the majority of the parameters. The addition of a compost material improved the blends, while clay and fertilizer additions did not result in greater soil quality or plant yield. Dredge showed to be a suitable material in manufactured soil blends for beneficial reuse.
