Coupling Sustainable Production Analysis to Field Trial Data

This research explores the sustainable resource access and management strategies in agriculture by analyzing field trial data. The study focuses on the Ames, IA, 25-acre experiment and evaluates the potential value-added through ecosystem services such as carbon sequestration, reduced nutrient runoff, and erosion control. The implementation of innovative management strategies and the utilization of field trial data for national resource assessment are highlighted. The results and future plans for the research are discussed.

  1. Coupling Sustainable Production Analysis to Field Trial DataDave Muth, Idaho National Laboratory U.S. Department of Energy Office of Biomass Program February 23, 2010

  2. Sustainable Resource Access

  3. Limiting factor models exist, We’re building a framework where models can plug together. Technical Approach

  4. Analysis Framework Architecture

  5. Case Study: Ames, IA 25 Acre Experiment Current Analysis Approach: Erosion alone indicates that full removal is sustainable Analysis with SOC: Conventional tillage does not provide sustainable resource, limited availability through no till Potential value added through other ecosystem services: • Carbon sequestration • Reduced nutrient runoff • Reduced erosion Implementing Innovative Management Strategies: Consistent sustainable resource available

  6. Utilizing Field Trial Data Through the Residue Removal Tool • Sustainable ag residue removal for national resource assessment Implemented in a highly efficient iterative schema

  8. Modeled Removal Rates - Corn Stover • No Stover Removal • Grain and Cobs: CCM on combine mix • Moderate Removal: Combine residue spreader disengaged, bale windrow left behind • Moderately High Removal: Bar rake run over standing stubble, bale windrow • High Residue Harvest: Flail shredder cutting standing stubble and collecting flat residue, bale windrow

  10. Adair County, Iowa Example212 Kennebec Silt Loam 0% to 2% Slope 10 Year Average Yield: USDA 10 Year Baseline Projection: USDA 10 Year Baseline Projection plus 10%:

  11. Results For RP Field Trial Counties

  12. Other Notes and Future Plans • National Assessment capabilities will be part of the core tool over the next few months • Quantitative carbon will brought online and used to revise the national runs over the next year • DAYCENT developers joining the team for quantitative carbon modeling • Significant I-Farm enhancements will be utilized within the tool over the next 6-9 months • Discussions and planning on moving sub-field will ramp up over the next year
