Optimal combinations of production and conservation practices need to be identified to increase long-term agricultural productivity and enhance the natural resource base on which rural economies depend. Problematic to this task is identifying a suite of variables that capture not only producer profitability, but also whole-farm and other stakeholder non-market values. A 10-year research study that determined the effects of three alternative conservation practices (direct-seeding, crop rotations, and maximal residue management) on perennial grass seed productivity in environmentally sensitive western Oregon was used to demonstrate how alternative conservation practices not only affect bio-physical production processes, but socio-economic processes as well. Using direct quantitative measures of crop, soil, water, air, and wildlife resources; GIS estimates of land use, topography, and hydrology; physical effects model and index results; and anecdotal landowner comments, we show how various system processes are impacted differently by conventional benchmark production and alternative conservation practices. An integrated analytical model is envisioned as an approach to present solutions to multiple management objective interpretations that are otherwise limited by data availability, computational and theory methodology, and baroque stakeholder preferences. Including both market and non-market valuations in production system assessments not only determine the impacts of implementing conservation practices at a whole-farm level, but also provides an opportunity to compare different agricultural systems in different landscapes.
