This research evaluated differences in yields and associated downside risk from using no‐till tillage practices. Yields 442 paired experiments across the United States were with respect to six crops environmental factors including geographic location, annual precipitation, soil texture, time since conversion no‐till. Results indicated that mean for sorghum [ Sorghum bicolor (L.) Moench] wheat ( Triticum aestivum L.) greater than tillage. In addition, tended produce similar or grown on loamy...
Probit analysis identified factors that influence the adoption of precision farming technologies by Southeastern cotton farmers. Younger, more educated farmers who operated larger farms and were optimistic about future most likely to adopt site-specific information technology. The probability adopting variable-rate input application technology was higher for younger farms, owned land they farmed, informed costs benefits farming, farming. Computer use not important, possibly because custom...
Research on how land suitability affects yields and breakeven prices for switchgrass ( Panicum virgatum L.) grown as a bioenergy crop is lacking the U.S. Southeast. Data from 3‐yr multilocation experiment at Milan, TN, were analyzed to determine influence of soil drainage landscape position yield farm‐gate price. Plots seeded in 2004 with ‘Alamo’ 2.8, 5.6, 8.4, 11.2, 14.0 kg ha −1 pure live seed (PLS). split 2005 N was applied 0, 67, 134, 201 . Farm‐gate 5‐ 10‐yr production contracts...
Many studies on the adoption of precision technologies have generally used logit models to explain behavior individuals. This study investigates factors affecting intensity agriculture adopted by cotton farmers. Particular attention is given role spatial yield variability number farming adopted, using a count data estimation procedure and farm-level data. Results indicate that farmers with more within-field higher technologies. Younger better educated producers were significantly correlated....
Abstract This study determines the likely effect of cost-share incentives on participation in Tennessee forest Stewardship Program and identifies other factors that may contribute to participation. A random utility model is used determine probability a landowner will choose participate program. binary choice specified represent dichotomous decision logit procedure fit model. Data are obtained from mail surveys 4,000 randomly selected landowners. Results indicate attitudes knowledge forestry...
Adoption of precision agriculture technology has received considerable attention, but abandonment little. This paper identifies factors motivating adoption and soil sampling in cotton. Younger producers who farmed more cotton area, owned their cropland, planted non-cotton or used a computer were likely to adopt sampling. Those with area livestock abandon, while those longer, variable-rate fertilizer application less abandon
Purpose The US Department of Energy has a goal to make ethanol from biomass cost competitive with petroleum by 2012. Feedstock procurement is expected represent significant portion the operating costs for refinery that produces such as switchgrass. Thus, cost‐effective feedstock logistics will be key factor future development capital intensive cellulosic industry. purpose this paper analyze various logistic methods switchgrass production, harvesting, storing, and transportation....
Abstract As the global population increases and becomes more affluent, biomass demands for food biomaterials will increase. Demand growth is further accelerated by implementation of climate policies strategies to replace fossil resources with biomass. There are, however, concerns about size prospective demand environmental social consequences corresponding resource mobilization, especially concerning impacts from associated land‐use change. Strategically integrating perennials into...
Little is known about how yield‐ and profit‐maximizing N rates of switchgrass ( Panicum virgatum L.) respond to environmental influences. The objective this research was determine the most suitable yield response functions grown on four landscapes in Tennessee. Research conducted West Tennessee during a 7‐yr period including: (i) well‐drained level upland (WDLU), (iii) well‐ moderately floodplain (WDFP), moderate somewhat poorly drained eroded sloping (MDSU), (iv) (PDFP). considered were...
The economic impact of obtaining biomass could become significant to U.S. rural economies via the establishment a bioeconomy. In 2023, Bioenergy Technologies Office (BETO) and Oak Ridge National Laboratory provided road map obtain over billion tons for conversion bioenergy other products. Using information from this roadmap, study estimates potential positive negative impacts that occur because land use change, along with increased technological advances. This is achieved by using...
Yield increase in crops has occurred due to plant breeding and improved production management techniques. The amount of soybean the southern USA not been determined. objective this study was evaluate genetic improvements yield other important agronomic traits. ‘CNS’ ‘S‐100’ were chosen as representative ancestral lines from 1940s. ‘Ogden’ ‘Lee’, ‘Hill’ ‘Essex’, ‘TN 5‐85’, ‘Hutcheson’ released early 1950s, late 1950s 1970s, 1980s, respectively. experiments conducted Knoxville Experiment...
