Requiring that crop applications of manure be based on phosphorus content (P-standard) could increase poultry litter disposal costs, Microbial phytase reduces litter P content and could reduce litter disposal costs under a P-standard, For a representative Virginia turkey farm, phytase costs $2,500 and could increase value of litter used for fertilizer on the turkey farm by $390 and reduce supplemental P feed costs by $1,431. Based on assumed litter demand and supply, estimated litter export prices with phytase could exceed export prices without phytase by $3.81 per ton. Phytase net returns to the farm are an estimated $1,435.

Domestic tobacco producers have faced increasing competition from imported tobacco since the late 1970s. Much of the debate has centered on the unknown quality of imported tobacco. This study provides a discussion and clarification of the concept of quality, and demonstrates a method of measuring the average quality of imported tobacco. The results show that since 1977, imported tobacco has been steadily decreasing in average quality and moving toward lower quality producing countries and types of tobacco. The reasons for this decline are discussed along with the policy implications.

Much of the increase use of vertical coordination in the U.S. swine industry has taken place through contract production. While the incidence of contracting is much higher in nontraditional hog production areas, a growing number of Midwestern producers are being faced with contract options. A variety of contractual arrangements are available through feed companies, integrators, genetics firms, and packers. However, little is known about the profitability and risk characteristics of these alternatives. This research suggests that risk neutral producers in the Midwest would prefer independent production, and risk averse producers would prefer to choose among the various types of coordination arrangements.

A descriptive analysis and a survey of literature were used in this assessment of the transformation of the structure of production agriculture. The changes in production agriculture have important implications for resource use, population distribution in rural communities, and the survival of small farms. The shifting structural change in production agriculture as a response to economic and technological adjustments is not a temporary phenomenon. The economic and natural base of agriculture will change toward greater capital intensity and concentration of ownership, and will raise public policy questions in relation to the survival of a large farm population.
