Student Expectations and Preferences of Distance Course Delivery Methods AgEcon
Diebel, Penelope L.; Gow, Laura R..
Students in five courses offered with a variety of distance and on-campus delivery methods were surveyed to determine student expectations and post-evaluation of courses; student demographics; and student experiences and preferences with technology and course delivery methods. The response group was primarily degree seeking upperclassmen, taking a required course, equally split by gender and by delivery location. All students preferred a live class delivery method but videotape delivery appeared to have a higher student satisfaction level than satellite. On-campus students found simultaneous satellite delivery distracting but not detrimental to their learning experience. Students consistently misjudged the content and workload of courses.

Ethics and Agriculture: A Teaching Perspective AgEcon
Diebel, Penelope L..
Ethics and agriculture is a complex debate, but one in which agricultural economics students must be prepared to participate. There are many links between economics and ethic or moral philosophy. Classroom teaching tends to focus on discussion of issues involving behavioral ethics and disregards the teaching of philosophical ethics and its application in agricultural economics. A discussion is presented regarding the ethical context we have inherited in agricultural economics. I offer some broad moral philosophy concepts and an argument for providing students with tools to develop a philosophical ethics perspective of agricultural economics.

An Economic Comparison of Composted Manure and Commercial Nitrogen with Imperfect Information AgEcon
Berends, Patrick T.; Diebel, Penelope L.; Williams, Jeffery R.; Schlegel, Alan J..
The economic feasibility of fertilizing irrigated grain sorghum with compos ted manure is evaluated using net return budgeting and production function analysis. Although the use of compost is technically feasible, the economic analysis indicates that compost does not comprise a large percentage of the nitrogen source in the profit-maximizing combination with commercial fertilizer.

Potential Environmental Contamination From Conventional and Alternative Cropping Systems in Northeast Kansas AgEcon
Koo, Seungmo; Diebel, Penelope L..
Surface-water contamination from agricultural chemicals is a problem in northeast Kansas. The objective of this study is to compare potential atrazine, nitrogen, and sediment loadings from regional conventional and alternative cropping systems. Results indicate that several alternative systems have lower loading levels for atrazine and sediment than the conventional system, but higher loading levels for nitrogen

An Economic Analysis of the IFMPO AgEcon
Williams, Jeffery R.; Diebel, Penelope L..
The Integrated Farm Management Program Option (IFMPO) of the 1990 farm bill is designed to increase crop management flexibility and promote the use of resource-conserving crops. Economic analysis of this program indicates that, although the current format provides flexibility, it provides little economic incentive to adopt resource-conserving crop rotations.

A Yield Sensitivity Analysis of Conventional and Alternative Whole-Farm Budgets for a Typical Northeast Kansas Farm AgEcon
Diebel, Penelope L.; Llewelyn, Richard V.; Williams, Jeffery R..
This analysis compares net returns of conventional and alternative agricultural cropping systems in northeast Kansas, with and without government commodity programs. The highest net return is consistently from the alternative system, wheat/clover-sorghum-soybeans. Sensitivity analysis reveals that the economic performances of the alternative systems are sensitive to yield penalties.

An Economic Analysis of Soil Erosion Control and Low-Input Agriculture AgEcon
Diebel, Penelope L.; Taylor, Daniel B.; Batie, Sandra S.; Heatwole, Conrad D..
The Chesapeake Bay is a major water resource whose quality has been threatened by soil erosion and agrichemical contamination. The control of agricultural pollution of the Bay is one of the focal points of the 1987 Chesapeake Bay agreement formed by four states in the Bay's watershed (Virginia, Maryland, Pennsylvania, and the District of Columbia). Among the suggested solutions is the promotion of low-input agricultural practices. However, some low-input practices also include frequent cultivations of the soil for non-chemical weed control practices, which may induce erosion. This analysis uses a case study approach to determine agricultural practice selection and potential erosion under different soil erosion constraints. A multi-period mathematical...

Tradeoffs Between Water Quality and the Economic Impacts of Low-Input Agriculture in the Coastal Plain of Virginia AgEcon
Diebel, Penelope L.; Taylor, Daniel B.; Batie, Sandra S.; Heatwole, Conrad D..
Agricultural activities have been identified as major contributors to the non-point pollution of the Chesapeake Bay. Low-input agricultural practices are being considered to reduce pollution in areas adjoining the Chesapeake Bay. A multiperiod mathematical programming model was used to examine the potential adoption of low-input practices and to assess the environmental consequences of these activities under different policies. The results of these analyses indicate that tradeoffs exist among the types of non-point pollution produced under each policy. Only policies that retired productive agricultural land reduced all pollutant types.
