ECONOMIC ANALYSIS APPROACHES TO POTATO-BASED INTEGRATED CROP SYSTEMS: ISSUES AND METHOD

RePEc: Research Papers in Economics (2002)

Ricardo Labarta Scott M. Swinton J. Roy Black Siglinde Snapp Richard H. Leep

In response to stagnating yields and mounting pest problems, Michigan potato growers are investigating ways to bring manure and cover crops back into potato production systems. The alternative systems bring benefits and costs for monetary net returns, the variability of net returns, and environmental impacts. This paper reviews the likely yield and biological system effects of alternative potato production systems that incorporate manure and cover crops. After briefly considering research designs for gathering experimental versus farm field data, it reviews four economic analysis methods for evaluating alternative systems. All methods are illustrated with examples. First, for evaluating comparative average profitability, it reviews a) enterprise budgets, b) partial budgets, and c) break-even analysis. Second, for integrating environmental impacts into profitability analysis by using monetary measures of environmental effects, it introduces green budgets. Third, for evaluating efficiency trade-offs between profitability and environmental impacts, it covers trade-off frontiers. Finally, for comparing the variability of returns across systems (including for risk-averse decision makers), it introduces analysis of variance and stochastic dominance. These methods provide a basic set of tools for the economic analysis of changes in potato-based crop systems that should be adequate for most static comparisons of annual crop management practices.

2005 Michigan Feeder Steers Business Analysis Summary

RePEc: Research Papers in Economics (2006)

Eric Wittenberg J. Roy Black

This report summarizes the financial and production records of 5 Michigan feeder steer farms. To be included, the farms must have produced at least 50 percent of gross cash farm income from feeder steer sales. The records came from Michigan State University's TelFarm project and the Farm Credit Service system in Michigan. The values were pooled into averages for reporting purposes. Farm records were included if a farm financial summary was completed on 2005 data including beginning and ending balance sheets, plus income and expenses. The data were checked to verify that cash discrepancy was less than 10% of gross cash inflow and that debt discrepancy was less than $1,000. While considerable variation in the data exists, average values are reported in the summary tables.

COST OF ASPARAGUS PRODUCTION IN WESTERN MICHIGAN

RePEc: Research Papers in Economics (2002)

Barbara Dartt Norm Myers J. Roy Black John Bakker

This bulletin was developed to help producers as well as educators and agribusinesses working with producers to estimate costs of production and expected profit based on typical asparagus management strategies found in northwestern Michigan. The budget included in this bulletin will allow users to revise inputs based on their management strategies and calculate their expected cost and profit. This flexibility provides a decision aid to search for systems that generate higher net returns to the farm's resource base. The brief outline of cultural and pest management practices included in this publication should be supplemented with publications from Michigan State University or from other Universities. See the References section for resources. Many are available on-line.

Competitive with Farm Yield Insurance

Barry J. Barnett J. Roy Black Yingyao Hu Jerry R. Skees

This article compares risk reduction from MPCI and GRP crop insurance contracts. The analysis extends and improves on the existing area-yield insurance literature in four important respects. First, the geographical scope greatly exceeds that of previous work. Second, unlike previous efforts, the area is not assumed to consist only of those farms included in the analysis. Third, the analysis is based on the actual GRP indemnity function rather than the area-yield indemnity function commonly used in the literature. Fourth, the analysis avoids the questionable assumption that GRP scale can be optimized at the individual farm level. Even with a number of conservative assumptions favoring MPCI relative to GRP, results indicate that at least for some crops and regions GRP is a viable alternative to MPCI.

Farmers’ Crop Insurance Choices in Iowa and Michigan: Survey Summary

Staff Paper Series (2017)

Mary Doidge Hongli Feng David A. Hennessy J. Roy Black William M. Edwards

Crop insurance is an important tool that allows farmers to manage risks in agricultural production. This report is a summary of a survey of farmers’ crop insurance choices in Iowa, a state typical of the central US Corn Belt, and Michigan, a state with a more diversified crop portfolio. Survey data indicate that Michigan farmers were less likely to purchase insurance than Iowa farmers. A smaller share of Michigan farmers received an indemnity payment from 2011 to 2015 than those in Iowa. Michigan farmers were more likely to report that they felt they have paid more for crop insurance policies than they have received in indemnity payments. For farmers in Iowa, downside yield and price risk was rated most important by the largest number of respondents, followed closely by out-of-pocket premium price. The ranking of these two factors was reversed for farmers in Michigan. The cross-state differences reported by the survey respondents imply that the federal crop insurance program has different regional impacts. In order to assist in informed policy debate, it would be useful to understand how different regions can achieve all the potential benefits afforded by the program. Specifically, it will be useful to know whether Michigan farmers are not taking best advantage of existing crop insurance opportunities or whether simple adjustments could result in program uptake as high as in some other states.

Biological Availability of Manganese Sources and Effects of High Dietary Manganese on Tissue Mineral Composition of Broiler-Type Chicks

Poultry Science (1984)

J. Roy Black C. B. Ammerman P. R. Henry R.D. MILES

An experiment was conducted with male broiler-type chicks to study tissue uptake of Mn as a measure of biological availability of Mn sources. A basal corn-soybean meal diet (116 ppm Mn) was supplemented with 0, 1000, 2000, or 4000 ppm Mn as either reagent grade sulfate, carbonate, or monoxide and fed ad libitum for 26 days. No toxic effects were noted as expressed by feed intake, weight gain, feed conversion, hematocrit, hemoglobin, or mortality. Analysis of Mn in tissues revealed a highly linear relationship between liver or bone Mn concentration and dietary Mn for all three sources. Manganese concentration in all tissues increased (P<.01) as dietary Mn increased. Liver and bone Mn accumulation appeared to be excellent indicators of relative biological availability. On the basis of tissue uptake and solubility tests, MnSO4 · H2O was the most available, followed by MnO and MnCO3, respectively. There were no effects of Mn source or level on concentration of Ca, P, Mg, Cu, Zn, or Fe in tissues studied.
