Incorporation of cover crops, sewage sludge, and animal manures are generally recommended to improve soil quality, reduce erosion, and provide additional sources of plant nutrients to improve crop yield and/or quality. In this study the influence of the above practices along with water and reclaimed wastewater application will be evaluated on soil carbon sequestration and emission of greenhouse gases, i.e. carbon dioxide, nitrous oxide, and methane under humid southeastern and arid Northwest agro climatic regions. Long-term impact of high rate application of manure (particularly poultry manure) on accumulation and fate of heavy metals and the bioavailability will be evaluated.
