This document summarizes Josiah McClellan's presentation on calculating the economic value of improved sustainability in soybean production. It discusses a model that evaluates management templates for soybeans across different soil textures and tillage practices. The model considers yield, sustainability metrics, and profitability. It sorts and optimizes templates based on these factors. The conclusions are that the model is better suited for broader trend analysis than operational decisions. It suggests integrating the model with field work to obtain real-world data.

- 17. Conclusions • As long as sustainability performance is calculated on an efficiency basis (per unit of production), sustainability and yield scores will track closely. • More variability between sustainability and profitability • The impact of crop rotation on sustainability performance calculations is understated. While single-crop sustainability assessments are straightforward, rotational assessments present multiple permutations to reference. • The utility of a yield/sustainability/profitability model may be limited as an operational decision support tool. • The model would have more utility on a larger, trend-centric scale, narrowing the list of management changes that would positively impact yield, sustainability and profitability together. Suggested Next Steps • Integrate the model into ongoing field work, to obtain real-world results and conduct meaningful statistical analysis. Conclusions and Suggested Next Steps
