Modeling Agricultural Outcomes In A Warmer, Wetter Vermont, Rachel Mason
Modeling Agricultural Outcomes In A Warmer, Wetter Vermont, Rachel Mason
Graduate College Dissertations and Theses
This thesis aimed to model agricultural outcomes that are important to Vermont dairy farms and their surrounding communities -- runoff, erosion, nitrogen and phosphorus losses, crop yields, and timeliness of farm operations -- under a set of possible future climates. The Agricultural Policy/Environmental eXtender (APEX) model was used for this work, and the models were calibrated using data from a project that measured most of these outcomes on a set of local farms. The model setup and calibration methodology is thoroughly documented and may be a useful starting point for others who are new to agricultural modeling.
Applied to two …
Organic Dairy Profitability In Vermont: Measuring The Impacts Of Management And Market Forces On Farm Financial Performance, Jonathan Patrick Walsh
Organic Dairy Profitability In Vermont: Measuring The Impacts Of Management And Market Forces On Farm Financial Performance, Jonathan Patrick Walsh
Graduate College Dissertations and Theses
The total number of operating dairy farms in the US has decreased by 74.1% over the past 25 years, dropping from 155,339 in 1992 to just 40,219 in 2017. As milk prices have fallen and become more volatile, profit margins have tightened, causing farmers to leave the business due to low profitability. Some Vermont farmers are currently looking for new economic strategies. One approach has been to transition from conventional to organic production in order to take advantage of better prices and new market opportunities. In order to make production decisions, farmers need accurate financial information on the costs and …
Consumer Support For Renewable Energy Systems: A Case Study Of Community Biodigesters In Vermont, Katelynn Maria Conedera
Consumer Support For Renewable Energy Systems: A Case Study Of Community Biodigesters In Vermont, Katelynn Maria Conedera
Graduate College Dissertations and Theses
From the steady rise in dairy farm closures to concerns over algae blooms in Lake Champlain, Vermont’s dairy industry is facing a multitude of challenges. While many potential solutions have been proposed, this study focuses specifically on community anaerobic digester systems (CADS) to aid in manure management, help to mitigate runoff, produce renew energy, and even provide an alternative revenue source to participating farms. CADS technology converts the gas emissions from manure and other organic substances into biogas through a process called anaerobic digestion. Unlike traditional on-farm biodigesters, which are often only financially viable for the largest dairy farms, CADS …
