A COMPARISON OF SUBJECTIVE AND HISTORICAL CROP YIELD PROBABILITY DISTRIBUTIONS AgEcon
Pease, James W..
Forecast distributions based on historical yields and subjective expectations for 1987 expected crop yields were compared for 90 Western Kentucky grain farms. Different subjective probability elicitation techniques were also compared. In many individual cases, results indicate large differences between subjective and empirical moments. Overall, farmer expectations for 1987 corn yields were below those predicted from their past yields, while soybean expectations were above the historical forecast. Geographical location plays a larger role than crop in comparisons of relative variability of yield. Neither elicitation technique nor manager characteristics have significant effects on the comparisons of the forecasts.

COST EFFECTIVENESS OF NUTRIENT MANAGEMENT AND BUFFERS: COMPARISONS OF FOUR SPATIAL SCENARIOS AgEcon
Bonham, John G.; Bosch, Darrell J.; Pease, James W..
Policymakers are seeking cost effective methods to reduce nutrient pollution from agriculture. Predicted costs and pollution reductions from nutrient management and buffers are evaluated under four spatial scenarios describing a watershed. Results will help policymakers evaluate alternative Best Management Practices (BMPs) for water quality protection in agriculture.

Cost-Effectiveness of Nutrient Management and Buffers: Comparisons of Two Spatial Scenarios AgEcon
Bonham, John G.; Bosch, Darrell J.; Pease, James W..
Farmers and taxpayers would benefit from more cost-effective agricultural nutrient pollution control measures. The objectives of our study are (1) to assess compliance costs and reductions in phosphorus loadings from implementation of nutrient management and riparian buffers; and (2) to estimate how the spatial scenario, which is the method of representing farms within the watershed, affects estimated compliance costs and reductions in phosphorus deliveries. Estimated compliance costs are quite sensitive to the spatial scenario. Buffers are more cost-effective than nutrient management under one of the two spatial scenarios, whereas nutrient management is more cost-effective under the other scenario. Shifts to more erosive crops reduce the effectiveness...

FARM ADVISORY SERVICES AND PESTICIDE TOXICITY ON COTTON AND PEANUTS IN THE ALBEMARLE-PAMLICO WATERSHED AgEcon
Mitra, Sonali; Bosch, Darrell J.; Taylor, Daniel B.; Pease, James W..
According to a Virginia-North Carolina watershed survey, farmers view advisory services as having the effect of decreasing pesticide use. However, analysis of pesticide use shows that hired staff, scouting personnel, and extension agents are associated with higher pesticide toxicity applied to cotton while chemical dealers and scouting personnel are associated with higher toxicity applied to peanuts.

IMPACTS OF WITHIN-FARM SOIL VARIABILITY ON NITROGEN POLLUTION CONTROL COSTS AgEcon
Vandyke, Laura S.; Bosch, Darrell J.; Pease, James W..
The effects of considering variable within-farm soil runoff and leaching potential on costs of reducing nitrogen losses are analyzed for a Virginia dairy. Manure applications may cause nitrogen losses through runoff and leaching because of factors such as uncertain nitrogen mineralization. Farmers can reduce nitrogen control costs by applying manure on soils with less nitrogen loss potential. Ignoring within-farm soil variability may result in overstating the farm's costs of reducing nitrogen losses.

Reducing Crop Nutrient Applications: The Yield Reserve Program AgEcon
Metcalfe, Todd; Bosch, Darrell J.; Pease, James W..
A proposed Yield Reserve Program designed to compensate farmers for any reduced yields resulting from reduced nitrogen (N) application rates below recommended rates is evaluated. Assuming that farmers currently follow extension recommendations for applying N, Yield Reserve Program participation reduces expected net revenue by $10 to $13/ha. The Yield Reserve Program reduces expected net revenue by $17 to $20/ha for farmers who apply N to maximize expected net revenue. Farmers’ costs of participation increase with lower probabilities of inadequate rainfall and higher corn prices and decline with higher N prices. The Yield Reserve Program can significantly reduce N applications to cropland, which may reduce N content of surface waters, but the costs to...

Reinventing Regulation of Agriculture: Alternative Performance Standards for Concentrated Animal Feeding Operations AgEcon
Pease, James W.; Bosch, Darrell J..
Concentrated Animal Feeding Operations (CAFOs) are point sources of pollution and require Clean Water Act permits. The 2003 regulations allow Large CAFOs to propose alternative performance standards (APS) that offer equivalent or better environmental performance than the baseline technology. Principal obstacles to APS success include the complexities of demonstrating superior performance, cost uncertainties for obtaining approval, CAFO risks of participation, intra-organizational barriers of permitting agencies, and potential lawsuits brought by environmental groups. Despite obstacles, APS offers potential for technology innovations and reduced environmental compliance costs.
