2013 Annual Report
1a.Objectives (from AD-416):
Determine effects of crop residue removal on soil quality.
1b.Approach (from AD-416):
On-going studies at the ISU Agronomy and Agricultural Engineering Research Center (AAERC) will be enhanced by providing more rapid soil quality analyses and interpretation of information. An increased amount of crop response, nutrient uptake, and nutrient removal data will be collected. This study will complement the ARS Renewable Energy Assessment Project (REAP) team efforts with similar resources going to Morris, MN; St. Paul, MN; Lincoln, NE; Brookings, SD; University Park, PA; Akron, CO; and Florence, SC; Equal resources per the SunGrant program guidelines will go to university partners at each location to strengthen the research and technology transfer relationships.
Multi-location field studies near Ames, IA, Morris, MN, St. Paul, MN, Lincoln, NE, University Park, PA, Florence, SC, and Brookings, SD, were continued for a fifth and final year. A five-year summary of results was presented to the Department of Energy (DOE) for their biennial program review and received excellent ratings by the review panel. Several aspects of the study are being summarized for a special issue of Bioenergy Research. Industry support for the research conducted by members of the ARS Renewable Energy Assessment Project (REAP) team and their university partners as part of the Sun Grant Regional Partnership led to a request to refocus and rebrand the group as the “Resilient Economic Agricultural Practices” team. In addition, the project was selected as one of the first two test cases for the USDA-ARS Agricultural Technology Innovation Partnership (ATIP) program. The modeling component led by DOE collaborators from the Idaho National Laboratory and now known as the Landscape Evaluation Assessment Framework (LEAF) was nominated for a Research & Development 100 award.
