Attributes Preferred and Premiums Offered for Naturally Produced Beef Cattle AgEcon
Springer, Job D.; Biermacher, Jon T.; Childs, M. Dan; Alkire, Deke O.; Grooms, Brandon.
A growing number of beef cattle producers in the US are using limited information to determine whether or not it would be economical for them to grow naturally produced cattle. The objective was to discover the attributes that marketing companies prefer for the naturally produced cattle they purchase, and to elicit the price premiums being offered for cattle that possess these attributes. Results of a phone survey of companies that purchase natural cattle show that 27 out of 32 companies report their willingness to pay a premium of $5.95/cwt for cattle that have never received antibiotics, ionophores, hormones or animal by-products.

Determining Key Factors of Influence on the Profitability of Retaining Cull Cows Beyond Culling AgEcon
Amadou, Zakou; Raper, Kellie Curry; Ward, Clement E.; Biermacher, Jon T.; Cook, Billy.
Factors influencing the profitability of retaining and feeding cull cows beyond culling were investigated. First, a price response function is estimated using 19 years of monthly price data as reported by Agricultural Market Services (AMS). Net returns are then estimated using data from a three year cull cow feeding experiment conducted at The Samuel Roberts Noble Foundation and used to examine the relative effect of various factors on net returns. Results showed the importance of average daily gain increases across feeding periods while feeding system is also an important contributing factor to net returns.

Determining Optimal Levels of Nitrogen Fertilizer Using Random Parameter Models AgEcon
Tumusiime, Emmanuel; Brorsen, B. Wade; Mosali, Jagadeesh; Johnson, Jim; Locke, James; Biermacher, Jon T..
The parameters of yield response functions can vary by year. Past studies usually assume yield functions are nstochastic ‘‘limited’’ stochastic. In this study, we estimate rye– ryegrass yield functions in which all parameters are random. The three functional forms considered are the linear response plateau, the quadratic, and the Spillman-Mitscherlich. Nonstochastic yield models are rejected in favor of stochastic parameter models. Quadratic functional forms fit the data poorly. Optimal nitrogen application recommendations are calculated for the linear response plateau and Spillman-Mitscherlich. The stochastic models lead to smaller recommended levels of nitrogen, but the economic benefits of using fully stochastic crop yield functions are small because...

Determining Optimal Levels of Nitrogen Fertilizer Using Random Parameter Models AgEcon
Tumusiime, Emmanuel; Brorsen, B. Wade; Biermacher, Jon T.; Mosali, Jagadeesh; Johnson, Jim; Locke, James.
The parameters of yield response functions can vary by year. Past studies usually assume yield functions are nonstochastic or ‘limited’ stochastic. In this study, we estimate rye-ryegrass yield functions where all parameters are random. Optimal nitrogen rates are calculated for two yield response functions: linear response plateau and quadratic. Nonstochastic models are rejected in favor of stochastic parameter models. However, the economic benefits of using fully stochastic models are small since optimal nitrogen rates do not differ greatly between stochastic and nonstochastic models.

Economic Challenges of Small-Scale Vegetable Production and Retailing in Rural Communities: An Example from Rural Oklahoma AgEcon
Biermacher, Jon T.; Upson, Steve; Miller, David C.; Pittman, Dusty.
Information regarding the economic potential of producing and retailing vegetables in rural communities is limited. This study determined the actual net return from producing and on-site retailing a mix of produce in a rural Oklahoma community and determined if consumers in the region were willing to pay differentiated prices for the locally grown vegetables. Although the project did not generate a profit, a wealth of insightful information was gained. Results show that a substantial number of consumers were willing to pay premiums for certain types of produce; however, there were not enough such consumers to overcome the production and harvesting expenses.

Economic Potential of Substituting Legumes for Synthetic Nitrogen in Warm Season Perennial Grasses used for Stocker Cattle Grazing AgEcon
Kering, Maru K.; Biermacher, Jon T.; Reuter, Ryan; Butler, Twain; Springer, Job D.; Rogers, James K.; Blanton, John, Jr.; Bouton, Joe H.; Guretzky, John A..
Stocker cattle grazing warm season perennial grasses is an important economic activity in the southern Great Plains. Substantial increases in the price of nitrogen fertilizer is negatively affecting forage producers’ profitability. Two alternative nitrogen management systems that use annual and perennial legumes have been developed for bermudagrass pastures. The goal of the study is to determine if the legumes systems are more profitable than the conventional practice of applying synthetic sources of nitrogen. Results of the two-year grazing study show that the legume systems could not compete economically with the common practice.

Economic Potential of Using High Tunnel Hoop Houses to Produce Fruits and Vegetables AgEcon
Donnell, Jeri; Biermacher, Jon T.; Upson, Steve.
Abstract Hoop house plasticulture has been promoted as a production technology that allows fruit and vegetable crops to be grown in the cool season months in early spring and late fall. At this time little information regarding the economics of hoop house plasticulture is available. Two fruit and vegetable production systems were developed for growing conditions in south-central Oklahoma. The first system has a spinach crop followed by field tomato, and the second system has annually produced strawberry followed by yellow and zucchini squash. Crop production data were collected in a three-year randomized and replicated experiment. The objectives were (1) to determine the expected cost of production for each crop and systems, (2) to determine the...

Effect of Nitrogen Fertilization and Liming on Rye-Ryegrass Yield and Soil pH Dynamics AgEcon
Tumusiime, Emmanuel; Brorsen, B. Wade; Biermacher, Jon T.; Mosali, Jagadeesh.
Using ammonium based nitrogen fertilizers in crop production has been shown to acidify soils. Lime used to correct soil pH is an important cost to producers. Recommendations of the optimal level of nitrogen to apply typically ignore the cost of lime created by nitrogen fertilization. This study was aimed to estimate soil pH change in response to nitrogen and lime application, and determine the effect of considering the cost of lime on recommendations about the optimal level of nitrogen. Yield response and pH functions were estimated and used to determine optimal levels of inputs. The effect of the cost of lime on recommendations about the optimal level of nitrogen was found to be marginal. Nitrogen acidification was found to be more severe with nitrogen...

Influence of Beginning Body Condition Scores on Net Returns From Feeding Cull Cows AgEcon
Amadou, Zakou; Raper, Kellie Curry; Biermacher, Jon T.; Cook, Billy; Ward, Clement E..
The impact of beginning body condition scores on returns from feeding cull cows was investigated in a two year experiment. In each of two culling years, physical performance data and financial data were measured at approximately monthly intervals for culls on pasture versus dry lot. Specifically, data was collected for cows culled in October 2007 and held through April 2008 and for cows culled in October 2008 and held through March 2009. We examine the sensitivity of net returns relative to the choice of body condition score as a sorting trigger for heavy versus thin cows. In this two year study, while a pasture system was generally more profitable than a drylot system, thin cows were typically more profitable than cows with higher BCS, regardless of the...

Managing Nitrogen and Phosphorus Nutrients for Switchgrass Produced for Bioenergy Feedstock in Phosphorus-Deficient Soil AgEcon
Haque, Mohua; Biermacher, Jon T.; Kering, Maru K.; Guretzky, John A..
There is limited information available explaining the agronomic and economic relationships between yield and nitrogen and phosphorus applications to growing switchgrass produced in phosphorus-deficient soils. The objective of this study was to determine the effects of nitrogen and phosphorus fertilizers on feedstock yield and measures of expected total cost, gross revenue, net return, and breakeven price of feedstock produced in phosphorus-deficient soils in the southern Great Plains. Data were collected from a three-year, two-location agronomic field study conducted in south-central Oklahoma. Two discrete nitrogen treatments (0 and 134 kg ha-1) and four discrete phosphorus treatments (0, 30, 60 and 90 kg ha-1) were randomly assigned to small plots...

Precision Nitrogen Fertilization Technology with Micro Grids AgEcon
Biermacher, Jon T.; Epplin, Francis M.; Brorsen, B. Wade; Solie, John B.; Raun, Bill.
Sensor-based precision fertilizer technologies are being developed and researched by production scientists. One such technology uses normalized difference vegetation index (NDVI) reflectance measurements of growing winter wheat plants and a nitrogen fertilizer optimization algorithm (NFOA) to determine nitrogen requirement necessary for plants to reach their yield plateau. A number of precision fertilizer application systems that use this technology are considered in this paper. A linear response stochastic plateau wheat yield function conditional on NDVI reflectance measurements is estimated and used within an expected profit-maximization framework to estimate upper bounds on the returns from the precision nitrogen application systems. The on-the-go...
