Analysis Of Beef Cattle Producers’ Propensity To Adopt Pasture Management And Prescribed Grazing East Of The 100th Meridian, Kristen Elizabeth Oliver
Masters Theses
Pasture management and grazing practices affect animal productivity, soil carbon storage and soil and water quality. Poor pasture and grazing management practices can cause soil erosion, nitrogen leaching, and runoff into streams and waterways. Based on a survey of cattle farmers east of the 100th meridian, the following two papers estimate how farm operator, farming operation, and attitudinal variables influence the propensity to use pasture management and prescribed grazing, as well as use of specific pasture management and prescribed grazing practices.
Key findings from the first paper are that individual pasture management and prescribed grazing practices are strong indicators …

Economic And Environmental Optimization In The Supply Of Switchgrass In Tennessee, Jia Zhong
Masters Theses
The low efficiency of collection, storage and transportation in the switchgrass supply chain has hindered the commercialization of a switchgrass-based biofuel industry, even given its ecological and environmental advantages in carbon sequestrate, soil quality, water use, and pollution pressure. Thus, designing a switchgrass-based supply chain balancing both environmental and economic performance is important to expedite the development of the cellulosic biofuel industry to meet the national energy plan.
The objectives of this study are to 1) determine economic cost and multiple environmental outcomes in feedstock supply chains and 2) identify the relation between the economic and environmental performances. The first …
