Technical Feasibility Of Small-Scale Oilseed And On-Farm Biodiesel Production: A Vermont Case Study, Emily J. Stebbins-Wheelock, Robert Parsons, Qingbin Wang, Heather Darby, Vernon Grubinger Dec 2012

Technical Feasibility Of Small-Scale Oilseed And On-Farm Biodiesel Production: A Vermont Case Study, Emily J. Stebbins-Wheelock, Robert Parsons, Qingbin Wang, Heather Darby, Vernon Grubinger

College of Agriculture and Life Sciences Faculty Publications

This article investigates the technical feasibility of small-scale oilseed production and on-farm processing of biodiesel and livestock feed using primary data from two Vermont farms. Results indicate that small-scale production of sunflowers, canola, and soybeans, and on-farm processing of livestock feed and biodiesel are technically feasible, but yields depend on many factors. Increased local expertise, information-sharing among the farm and Extension communities, and improved access to harvesting and processing equipment can improve productivity and efficiency. Additional experience in seed drying and expeller pressing techniques should reduce fat content in the seed meal, improve meal value, and improve oil production efficiency. …

Bioenergy Harvesting Impacts On Ecologically Important Stand Structure And Habitat Characteristics, Caitlin E. Littlefield, William S. Keeton Oct 2012

Bioenergy Harvesting Impacts On Ecologically Important Stand Structure And Habitat Characteristics, Caitlin E. Littlefield, William S. Keeton

Rubenstein School of Environment and Natural Resources Faculty Publications

Demand for forest bioenergy fuel is increasing in the northern forest region of eastern North America and beyond, but ecological impacts, particularly on habitat, of bioenergy harvesting remain poorly explored in the peer-reviewed literature. Here, we evaluated the impacts of bioenergy harvests on stand structure, including several characteristics considered important for biodiversity and habitat functions. We collected stand structure data from 35 recent harvests in northern hardwood-conifer forests, pairing harvested areas with unharvested reference areas. Biometrics generated from field data were analyzed using a multi-tiered nonparametric uni-and multivariate statistical approach. In analyses comparing harvested to reference areas, sites that had …

Pastoral Lease Assessment Using Geospatial Analysis, T P. Robinson, P E. Novelly, R Corner, Philip Thomas, A Russell-Browm Aug 2012

Pastoral Lease Assessment Using Geospatial Analysis, T P. Robinson, P E. Novelly, R Corner, Philip Thomas, A Russell-Browm

Resource management technical reports

Seven remote sensing based Vegetation Indices (NDSVI, STVI-3, NDVI, Green + Red, Red, Land Monitor and STVI-1) were tested for their potential to discriminate between “poor” and “good” range condition assessments in Western Australia’s pastoral rangelands. Indices were computed using the Australian Greenhouse Office National Carbon Accounting System (AGO NCAS) repository of calibrated Landsat TM/ETM+ mosaics. Discrimination potential was assessed at two levels of stratification – station level (identical to the stratification used to collect the traverse data), and functional group level (an aggregation of similar land systems);

Modeling Field-Scale Vulnerability To Pesticide Runoff, Atefeh Hosseini Jul 2012

Modeling Field-Scale Vulnerability To Pesticide Runoff, Atefeh Hosseini

School of Natural Resources: Dissertations, Theses, and Student Research

Identifying areas vulnerable to off-site agrichemical movement and surface and ground water contamination through conventional data collection is labor-intensive, costly and time-consuming. To promote efficient pesticide use and protect water resources, a process-based index model was previously developed to estimate landscape vulnerability to pesticide runoff and leaching at a watershed or regional scale using Soil Survey Geographic (SSURGO) data. Because mitigation of contamination requires implementation of best management practices, the model was adapted to the field scale. The field-scale model was developed based on a Digital Elevation Model (DEM) with 5 ´ 5 m resolution for a research site in …

Life Cycle Boundaries And Greenhouse Gas Emissions From Beef Cattle, Quentin M. Dudley Jul 2012

Life Cycle Boundaries And Greenhouse Gas Emissions From Beef Cattle, Quentin M. Dudley

Department of Agricultural and Biological Systems Engineering: Dissertations, Theses, and Student Research

Beef cattle are estimated to directly contribute 26% of U.S. agricultural greenhouse gas (GHG) emissions, and future climate change policy may target reducing these emissions. Life cycle assessment (LCA) of GHG emissions from U.S. feedlot beef cattle was conducted to compare methods of the U.S. Environmental Protection Agency (EPA) with a more complete evaluation of emissions. The inclusion of emissions from crop production for feed, associated land use change, and other minor factors nearly doubled GHG emissions associated with beef feedlots from the EPA Annual Inventory estimate of 1611 kgCO2e hd-1 yr-1 to 3182 ± 167 …
