This study empirically investigates environmental benefits at the watershed level from conservation practices, which are typically non-linear. A conservation tillage adoption model is linked to the Soil and Water Assessment Tool model to examine the effectiveness of various conservation policies aimed at improving water quality in an Iowa watershed.
