The random nature of soil loss under alternative land-use practices should be an important consideration of soil conservation planning and analysis under risk. Chance constrained programming models can provide information on the trade-offs among pre-determined tolerance levels of soil loss,...

This paper analyzes the effects of uncertain soil loss in farm planning models. A disaggregated approach was used because of an interest in examining the impact of probabilistic soil loss constraints on farm level decision-making. A stochastic programming model was used to consider different...

Every year, the federal government regulates how many pounds of summer flounder (while these fish are called summer flounder, they are caught throughout the year) can be caught along the eastern seaboard. Annually, the federal government sets the total allowable landings (TAL) based on...

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...

A conceptual optimal control theory model which considers farm level decision making with respect to soil management is developed. A simplified version of the theoretical model is applied to the Piedmont area of Virginia. The model includes the productivity impacts of both soil erosion and...

The complementary interaction between topsoil depth and technical progress for winter wheat in the Palouse region was found to strengthen the long run payoff to conservation tillage. Nonetheless, conservation tillage was found to be competitive with conventional tillage only if its current yield...

The cost estimates to meet agriculture reduction goals for the Bay run into the billions. Most cost models, however, are based on simplifying behavioral assumptions about public transaction costs, adoption rates, and implementation costs of agricultural nutrient-reducing practices (called best...

Using a translog production function, cereal production on state farms in Ethiopia between 1980 and 1985 was analyzed. The farms were found to be operating at constant returns to scale. Manual labor was under-utilized, while machinery and other modern inputs were over-utilized. Elasticities of...
