TY - JOUR T1 - The implications of alternative beliefs about soil-erosion-productivity relationships and conservation treatments for the economic dynamics of soil erosion on the southern Texas High Plains JF - Journal of Soil and Water Conservation SP - 368 LP - 375 VL - 52 IS - 5 AU - Julie A. Bunn Y1 - 1997/09/01 UR - http://www.jswconline.org/content/52/5/368.abstract N2 - This article presents two distinct views, both supported by research and expert opinion, of the underlying soil-erosion-productivity relationships in semi-arid agriculture on the southern Texas High Plains. The two views are incorporated into farm-level optimization simulations appropriate to semi-arid rainfed agriculture in order to analyze their affect on economic and resource dynamics over the soil horizon. The simulations demonstrate that the two views have quite different implications for recommended conservation methods and for cropping system choice dynamics. ER -
