Research Project: Soil and Water Management to Improve Carbon Sequestration and Mitigate Trace Gas Emissions


2013 Annual Report

1a. Objectives (from AD-416):
Investigate balanced agricultural production practices to enhance soil carbon storage and minimize greenhouse gas emissions under corn production in humid and dry temperate climate regions.

1b. Approach (from AD-416):
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.

3. Progress Report:
No progress was made this fiscal year. This project contributes to in-house project Objective 2B: "Evaluate the effects of deficit irrigation practices on potato yield and tuber quality". This is a non-funded Specific Cooperator Agreement intended to explore collaborations and provide opportunities for student internship with the expectation of funding to come from the cooperating university. These activities did not begin due to budget shortfalls at Savannah State University. We hope the situation will improve in the coming years.
