ADOPTION OF BACKGROUNDING ON COW-CALF FARMS AgEcon
Popp, Michael P.; Faminow, Merle D.; Parsch, Lucas D..
A discrete choice model is used to analyze the decision to feed or sell calves at weaning. After accounting for regional factors, results show that operator perceptions toward profitability, risk, and facilities as well as control over production and attention to marketing impacted retained ownership of calves. Farm size had a minimal impact.

Assessment of Alternative Fuel Production from Switchgrass: An Example from Arkansas AgEcon
Popp, Michael P..
As the hunt for renewable energy sources from agriculture intensifies, many agricultural producers are contemplating what crops to grow in the foreseeable future. On the one hand, there are traditional food crops, such as soybean, corn, and wheat, which have recently enjoyed a spike in prices, primarily because of the seemingly ever-growing demands of the corn to ethanol industry. On the other hand, there are the lesser-known perennial energy crops, such as switchgrass. Although much information on various aspects of switchgrass production exists, this paper discusses the adaptation of existing production and processing information to Arkansas conditions as a potential alternative to crop production.

Assessment of two alternative switchgrass harvest and transport methods AgEcon
Popp, Michael P.; Hogan, Robert J., Jr..
As the search for renewable energy sources from agriculture intensifies, many agricultural producers are contemplating production of a native perennial grass species, switchgrass (Panicum Vigratum, L.). While much information on various aspects of switchgrass production exists, this paper discusses implications of two alternative harvesting and transportation methods that may be suitable for Arkansas conditions. Results suggested that module building compared to the simpler round baling technology may be a promising alternative.

Economic Evaluation of Soybean Fungicide Seed Treatments AgEcon
Popp, Michael P.; Rupe, John; Rothrock, Craig.
The effect of nine different fungicide seed treatments for soybeans were tested from 2004 to 2007 at Keiser, Stuttgart, and Hope, Arkansas. While seedling emergence was effective across all treatments, only three treatments showed statistically significant differences in partial returns, defined as gross revenue minus seed and seed treatment costs. Comparisons of the regret a producer would experience as a result of non-optimal seed treatment suggested that broad spectrum seed treatment could enhance profitability by an average of $32 per acre with similar treatment recommendations across a range of seeding rates, output prices and study conditions.

Envesting in an Agricultural Legacy: Impact of a Targeted Young and Beginning Farmer Loan Program in Arkansas AgEcon
Goeringer, L. Paul; Goodwin, Harold L., Jr.; Dixon, Bruce L.; Popp, Michael P..
America’s agricultural producers continue to age. According to the U.S. Census of Agriculture, the average age of farm operators increased from 55.3 in 2002 to 57.1 in 2007. During the same period, the Census shows a thirty percent decrease in the number of farmers under the age of 25. Young and beginning producers (YBPs) entering agriculture can be faced with high startup costs and the lack of land to own or rent. To address this potential shortage of future farmers, we propose a program for the Farm Credit System to assist YBPs by offering Farm Service Agency guaranteed loans. In this program YBPs are given concessionary interest rates in consideration for adopting conservation and recommended “best” practices. To gauge the impact of the loan...

Expected Changes in Farm Landscape with the Introduction of a Biomass Market AgEcon
Popp, Michael P.; Nalley, Lawton Lanier; Vickery, Gina B..
This study examines how the introduction of dedicated energy crops—switchgrass and forage sorghum—may affect Arkansas’ crop allocation decisions. The study captures crop production practices at the county or crop reporting district level. Results are in a static equilibrium framework and limited to a one-year ahead forecast. The model’s predictive success was evaluated by comparing 2007 model results with no energy crop production to actual acreages harvested. Switchgrass entered land use at approximately $25 and $35/dry ton in 2007 and 2008, respectively. Higher 2008 commodity prices for traditional crops caused lower switchgrass acreage peaks compared to 2007. Further, at higher biomass price levels—$45 to $55/dry ton depending on year and whether or not...

FACTORS AFFECTING THE ADOPTION OF VALUE-ADDED PRODUCTION ON COW-CALF FARMS AgEcon
Popp, Michael P.; Faminow, Merle D.; Parsch, Lucas D..
Factors that affect the decision to feed or sell calves at weaning are analyzed for Arkansas cow-calf operators. A discrete choice logit model is used to analyze the adoption of value-added cattle production. Farm size, human capital, perception of risk/returns and enterprise diversification are hypothesized to explain this decision. Regional factors and land quality are also accounted for. Operator perceptions towards risk, profitability and facilities were important. Production control and attention to marketing were also significant, but farm size and scale of cattle production had a minimal impact. Effects of human capital and off-farm labor opportunities need further investigation.

Going, Going, Almost Gone: How the Depletion of the Alluvial Aquifer Will Affect Cropping Decisions in the Arkansas Delta AgEcon
Popp, Michael P.; Nalley, Lawton Lanier; Vickery, Gina B..
The U.S. Geological Survey (USGS) has determined that agricultural irrigation in Arkansas’ Delta is unsustainable with significant negative economic repercussions on producers net returns affected by the Alluvial aquifer. This study examines how irrigation restrictions in that region would affect county net returns to crop production. It also considers the effect of planting less water-intensive bioenergy crops in the event biofuel markets become a reality. A constrained optimization model determines acreage allocations and net returns under three irrigation scenarios: i) no irrigation restrictions, ii) irrigation restrictions that lead to a sustainable Alluvial aquifer, and iii) irrigation restrictions that would lengthen the life of the Alluvial...

Hedging Break-Even Biodiesel Production Costs Using Soybean Oil Futures AgEcon
Graf, Johannes; McKenzie, Andrew M.; Popp, Michael P..
The effectiveness of hedging volatile input prices for biodiesel producers is examined over one- to eight-week time horizons. Results reveal that hedging break-even soybean costs with soybean oil futures offers significant reductions in input price risk. The degree of risk reduction is dependent upon type of hedge, naïve or risk-minimizing, and upon time horizon. In contrast, cross-hedging break-even poultry fat costs with soybean oil futures failed to reduce input price risk.

How A Cap-and-Trade Policy of Green House Gases Could Alter the Face of Agriculture in the South: A Spatial and Production Level Analysis. AgEcon
Nalley, Lawton Lanier; Popp, Michael P.; Fortin, Corey.
With the Waxman-Markey Bill passing the House and the Obama administration’s push to reduce carbon emissions, the likelihood of the implementation of some form of a carbon policy is increasing. This study estimates the greenhouse gas (GHG) emissions of the six largest crops produced in Arkansas using 63 different production practices as documented by University of Arkansas Cooperative Extension Service. From these GHG estimates a baseline state “carbon footprint” was estimated and a hypothetical cap-and-trade carbon reduction of 5, 10, and 20% was levied on Arkansas agriculture. Results show that while a modest reduction in GHG emissions (5%) would only affect crop allocations amongst certain crops while marginally reducing state net returns, a 20%...

How a National Carbon Policy Could Affect Grain Variety Selection: The Case of Rice in Arkansas AgEcon
McFadden, Brandon R.; Nalley, Lawton Lanier; Popp, Michael P..
This study conducts a life cycle assessment (LCA) of carbon emissions and estimates the carbon sequestered in 14 commonly sown rice varieties across the Arkansas Delta. Given the uncertainty regarding future carbon legislation, and increased consumer and industry demand for “greener” products, this study estimates how potential carbon policies would affect rice cultivar selection Hybrid rice varieties, given their higher yield and higher yield per unit of green house gas (GHG) emission, are better positioned to take advantage of any increase in consumer demand for “greener” products and/or absorb any government policy better than conventional rice cultivars.

Irrigation Restriction and Biomass Market Interactions: The Case of the Alluvial Aquifer AgEcon
Popp, Michael P.; Nalley, Lawton Lanier; Vickery, Gina B..
The U.S. Geological Survey has determined that irrigation in Arkansas’ Delta is unsustainable. This study examines how irrigation restrictions would affect county net returns to crop production. It also considers the effect of planting less water-intensive bioenergy crops—switchgrass and forage sorghum—in the event biofuel markets become a reality. Results suggest that sustainable irrigation restrictions without bioenergy crops would decrease producer returns by 28% in the region. Introducing these alternative crops would both reduce groundwater use and may restore state producer returns, albeit with significant spatial income redistribution to crop production throughout the state.

Modeling Interactions of a Carbon Offset Policy and Biomass Markets on Crop Allocations AgEcon
Popp, Michael P.; Nalley, Lawton Lanier.
Arkansas cropping pattern changes at the county level were estimated under various scenarios involving a likely decline in water availability, the development of a biomass market for renewable energy production, and the potential of a widely used carbon offset market. These scenarios are analyzed separately and jointly to determine which of the three scenarios is expected to have the largest impact on net (emissions – sequestration) greenhouse gas (GHG) emissions, renewable fuels feedstock supply, and producer net returns. Land use choices included conventional crops of rice, cotton, soybean, corn, grain sorghum, pasture, and hay. Specialty crops of loblolly pine and switchgrass were modeled for their respective potential to sequester carbon and provide...

Modeling the Effects of Cap and Trade and a Carbon Offset Policy on Crop Allocations and Farm Income AgEcon
Nalley, Lawton Lanier; Popp, Michael P..
A static, producer profit maximization framework is used to capture county level land use choice on the basis of profitability, greenhouse gas (GHG) emissions to the farm gate as well as soil carbon sequestration as affected by tillage and soil type. Policy scenarios of a 5% GHG cap on agricultural emissions in conjunction with a carbon offset payment system, designed to provide producer payments for net carbon footprint (GHG emissions – soil carbon sequestration) reductions compared to a baseline are evaluated to determine potential changes to land use and or producer income as a result of different policy scenarios. Results suggest that a policy solely targeted at emissions can be counterproductive in the sense that acreage reductions of more...

SPATIAL YIELD RISK ISSUES: COMPARING YIELD RISK ACROSS REGION, CROP AND AGGREGATION METHOD AgEcon
Popp, Michael P.; Rudstrom, Margaretha; Manning, Patrick M..
Crop yield risk analysis is difficult since historic field level yields are often not available. Spatially aggregated yield data are available, however, but aggregation distortion for farm level analysis may exist. This paper addresses how much aggregation distortion to expect and offers some adjustment solutions across crops and production regions.

Strategic Alliance and Joint Venture Agreements in Grain Marketing Cooperatives AgEcon
Fulton, Joan R.; Popp, Michael P.; Gray, Carolyn.
Strategic alliance and joint venture agreements are analyzed using the prisoners' dilemma and assurance problem models of game theory. Hypotheses regarding the factors contributing to the success/failure of the agreements are formulated. These hypotheses are confirmed with data from interviews with managers of grain marketing cooperatives in eastern Colorado. Our results suggest that joint venture and strategic alliance agreements represent an opportunity for local cooperatives to take advantage of size economies while maintaining their individual business identities. Successful agreements require not only attention to the financial and operational components but diligence in the interpersonal dynamics of trust, commitment, and open communication.

The Impact of Reducing Greenhouse Gas Emissions in Crop Agriculture: A Spatial- and Production-Level Analysis AgEcon
Nalley, Lawton Lanier; Popp, Michael P.; Fortin, Corey.
With the Waxman-Markey Bill passing the House and the administration’s push to reduce carbon emissions, the likelihood of the implementation of some form of a carbon emissions policy is increasing. This study estimates the greenhouse gas (GHG) emissions of the six largest row crops produced in Arkansas using 57 different production practices predominantly used and documented by the University of Arkansas Cooperative Extension Service. From these GHG emission estimates, a baseline state “carbon footprint” was estimated and a hypothetical GHG emissions reduction of 5, 10, and 20 percent was levied on Arkansas agriculture using a cap-and-trade method. Using current production technology and traditional land use choices, results show that the trading of...
