Última Economic Evaluation of Wind Energy as an Alternative to Natural Gas Powered Irrigation AgEcon Guerrero, Bridget L.; Amosson, Stephen H.; Marek, Thomas H.; Johnson, Jeffrey W.. High natural gas prices have agricultural producers searching for alternative energy sources for irrigation. The economic feasibility of electric and hybrid (electric/wind) systems are evaluated as alternatives to natural gas powered irrigation. Texas Panhandle and Southern Kansas farms are assessed with a quarter-mile sprinkler system, three crops, and two pumping lifts. Breakeven points identify the price at which conversion from a natural gas irrigation system to an electric or hybrid system is cost effective. Results indicate electricity is a more feasible energy source for irrigation and policy changes such as net metering are necessary to make hybrid systems viable.

Ano: 2010 URL: http://purl.umn.edu/90680 Economic Analysis of Manure Harvesting Equipment in Feedyards for Dust Control AgEcon Bretz, Fran E.; Amosson, Stephen H.; Warminski, Patrick L.; Marek, Thomas H.. This study concentrated on one method of dust control which is harvesting manure with equipment. An economic analysis including hourly fixed and operational costs were performed on the following: tractor-pulled box scraper, front-end loader, dump truck, spreader truck, elevating scraper and tractor-pulled end dump. The purpose of this study was to generate cost data for feedyard owners/operators to reference when making manure management and equipment purchasing decisions.

Ano: 2010 URL: http://purl.umn.edu/56438 Economic Analysis of a Water Truck for Feedyard Dust Suppression AgEcon Amosson, Stephen H.; Bretz, Fran E.; Warminski, Patrick L.; Marek, Thomas H.. Dust created in feedyards can adversely affect cattle performance. Dust suppression can be accomplished by moistening pen surfaces with traveling gun(s) sprinklers, solid-set sprinklers, and water trucks. This study specifically addresses the fixed and operational costs associated with a water truck for various sized feedyards.

Ano: 2008 URL: http://purl.umn.edu/7032 Cost Analysis and Water Conservation Potential of Irrigation Technologies in the Texas Panhandle Water Planning Area AgEcon Almas, Lal K.; Vimlesh, K.; Girase, J.R.; Amosson, Stephen H.; New, Leon L.; Bretz, Fran E.; Marek, Thomas H.. Six irrigation systems are analyzed considering cost and potential water savings. The investment cost of furrow and drip is $115,800 and $260,120, respectively. The cost of quarter mile pivot ranges from $59,000 to $64,000. Per ac-in variable pumping cost ranges $9.96 to $14.86 assuming natural gas price $7.00 per MCF.

Ano: 2010 URL: http://purl.umn.edu/56517 ECONOMIC FEASIBILITY OF PRECISION IRRIGATION IN THE NORTHERN TEXAS HIGH PLAINS AgEcon Almas, Lal K.; Amosson, Stephen H.; Marek, Thomas H.; Colette, W. Arden. The benefit of changing to Variable Rate Irrigation (VRI) from uniform application methods needs to be assessed for technology adoption. Precision irrigation involves water application in optimum amounts. Results indicate that feasibility of precision irrigation depends on field variability, crop value, economies of scale, and useful life of the equipment.
