Erosion-Productivity Economics Model: A User's Guide

摘要

Analysis of natural resource policy options often requires the use of a consistent set of information which illustrates variability in production activities, physical characteristics, and soil productivity. The report describes a model (The Erosion Productivity Economics Model) capable of providing the information at any level of aggregation. For illustration purposes, the authors develop sample crop budgets, prices, yields, and erosion levels for 12 Major Land Resource Areas, 4 conservation tillage practices, and 4 land groups.
