Atrazine is the most widely used herbicide for corn and sorghum and the most commonly encountered in surface water and groundwater. In addition to water quality problems, atrazine poses hazards through atmospheric transport, food residues, and exposure of applicators and wildlife. It atrazine...

over potential sources of environmental degradation (see, for example, Shortle and Dunn 1986; Russell and Shogren 1993). Although partially related to scientific advances in measurement and detection, perceived risks due to chemical loading have intensified the pressure to more closely coordinate...

To what extent can a significant portion of the environmental benefits offered by CRP be maintained if CRP outlays are significantly reduced? Recent CARD research reported here in a succinct manner addresses the issue of economic and environmental trade-offs in CRP.

CRP (Conservation Reserve Program) renewal may depend on improved targeting of payments to maintain a significant portion of existing environmental and farm benefits at a reduced program cost. The authors consider three alternative renewal criteria: renewal of least expensive land first, renewal...

Contained in this paper are estimates of the benefits and costs of alternative soil conservation policies in a spatially and temporally consistent framework. The policies considered are implementation of soil conservation practices with an objective of reducing erosion to a site's tolerance...

The Central Nebraska Basin (CNB) is the site of intensive agricultural activity, in part because of the good irrigation supplies provided by the Middle Platte alluvial aquifer system. In this paper, the authors describe the integrated modeling system that addresses the economic and environmental...

The management practices farmers choose have significant effect on agricultural pollution. The authors analyze the adoption of alternative combinations of conservation practices and their impacts on fertilizer use, corn yield, and soil erosion in the Central Nebraska Basin, using a...

This report estimates the economic and environmental trade-offs of the 1995 Farm Bill policy options evaluated by FAPRI. Assessments are provided for the 1995 FAPRI baseline, 25 percent Normal Flex, and the Revenue Assurance program. The authors describe the modeling systems and the CEEPES-FAPRI...

Over the past decade, conservation compliance has reduced soil erosion. What will happen to these erosion benefits if commodity programs are eliminated or if the subsidy level is greatly reduced? This study investigates whether there will be a significant decline in the amount of acreage on...

The authors present an empirical model used to estimate the effects of alternative farming practices on potential nitrogen runoff and leaching in 128,591 National Resource Inventory sites across the Midwest and the Northern Plains of the United States. This model integrates the effects of soils,...
