Sustainable Resource Access

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

Analysis Framework Architecture

Case Study: Ames, IA 25 Acre Experiment Current Analysis Approach: Erosion alone indicates that full removal is sustainable Erosion (T=5.0) (t/acre/yr) Removal RateConv TillNo Till 0% % % Analysis with SOC: Conventional tillage does not provide sustainable resource, limited availability through no till SOC (lbs/acre/yr) Removal RateConv TillNo Till 0% % % Implementing Innovative Management Strategies: Consistent sustainable resource available SOC (lbs/acre/yr) Removal Rate NT w/Rye Cover NT w/Legume + Clover Cover 0% % % Potential value added through other ecosystem services: Carbon sequestration Reduced nutrient runoff Reduced erosion

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

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
