Última Will Variable Rate Application Technology Pay in Tennessee? AgEcon Cochran, Rebecca L.; Larson, James A.; Roberts, Roland K.; English, Burton C.. Costs differ among variable rate application systems. Most feasible in Tennessee are the 1-bin and 2-bin spreader beds mounted to existing chassis with an owner-added variable rate controller and global positioning system. Truck spreader systems required more acreage or larger custom charges making it difficult to breakeven and earn a profit.

Ano: 2004 URL: http://purl.umn.edu/34678 Factors Affecting Perceived Improvements in Environmental Quality from Precision Farming AgEcon Larkin, Sherry L.; Perruso, Larry; Marra, Michele C.; Roberts, Roland K.; English, Burton C.; Larson, James A.; Cochran, Rebecca L.; Martin, Steven W.. This study identified the factors that influenced whether farmers in the Southeastern United States perceived an improvement in environmental quality from adopting precision farming technologies (PFTs). Farmers with larger farms or higher yields were more likely to believe that they observed positive externalities associated with PFTs. Farmers who found PFTs profitable or who believed input reduction was important had higher probabilities whereas those with higher incomes or who were more dependent on farm income were less likely to perceive such benefits. Interestingly, the importance of environmental quality and length of time using PFTs were not found to affect the probability of perceiving an improvement in environmental quality.

Ano: 2005 URL: http://purl.umn.edu/42787 Effects of Alternative Lime Application Rates on Cotton Profitability with Varying Cover Crops, Nitrogen, and Tillage Methods. AgEcon Cochran, Rebecca L.; Larson, James A.; Roberts, Roland K.; Tyler, Donald D.. Soil acidity and cotton yields are influenced by cover crop, nitrogen, and tillage method. Applying half the recommended lime rate may be possible without reducing cotton yields. Using a nitrogen intensive cover crop and applying less nitrogen should mitigate the effects on soil acidity and yields.

Ano: 2005 URL: http://purl.umn.edu/35569 ADOPTION OF SPATIAL INFORMATION GATHERING TECHNOLOGIES AND VARIABLE RATE INPUT APPLICATION TECHNOLOGIES BY COTTON FARMERS IN THE SOUTHEAST AgEcon Martin, Steven W.; Roberts, Roland K.; English, Burton C.; Larson, James A.; Cochran, Rebecca L.; Goodman, W. Robert; Larkin, Sherry L.; Marra, Michele C.; Shurley, W. Donald; Reeves, Jeanne M.. Probit analysis identified factors influencing adoption of precision farming technologies by Southeastern cotton farmers. Younger, more educated farmers who operated larger farms and were optimistic about the future of precision farming were most likely to adopt site-specific information technology. The probability of adopting variable rate input application technology was higher for younger farmers who operated larger farms, owned more of the land they farmed, were more informed about the costs and benefits of precision farming, and were optimistic about the future of precision farming. Computer use was not important possibly because custom hiring shifts the burden of computer use to agribusiness firms.

Ano: 2004 URL: http://purl.umn.edu/42943 ANALYSIS OF BREAKEVEN YIELD GAINS AND INPUT COST SAVINGS FOR A COTTON YIELD MONITORING SYSTEM AgEcon Larson, James A.; English, Burton C.; Roberts, Roland K.; Cochran, Rebecca L.. Cotton yield monitors are a new technology and their costs have not been thoroughly evaluated. This research evaluated yield gains and input savings required to cover the cost of a monitor. Spreading monitor costs over multiple VRT decisions reduces the required yield gain or cost savings for any one decision.
