B9 - The costs of conservation practices to improve water quality in the state of Iowa.

Catherine Kling, Professor; Silvia Secchi, Philip Gassman, Manoj Jha, Lyubov Kurkalova, and Hongli Feng-Hennessy, Economics, Iowa State University. This study combines economic models with a watershed-based hydrological model, the Soil and Water Assessment Tool, to estimate the costs of obtaining water quality changes from a hypothetical, broad-based conservation policy. The practices analyzed include buffers, terraces, strip cropping, contouring, conservation tillage, land set-aside, and nutrient management strategies.
