Willow Harvesting Publications

Harvesting is the single largest cost in the production of short rotation woody crops (SRWC) like shrub 8 willow and previous systems tested in North America have not been effective for the size of material grown. The 9 objective of this study was to evaluate the performance of a single-pass, cut and chip harvester in conjunction with 10 two locally-sourced chip collection systems on 54 ha of coppiced willow harvests in New York State. Harvesting 11 and collection equipment was tracked for 153 loads over 10 days of harvesting using GPS dataloggers. Effective 12 material capacities (Cm) increased linearly with ...


The Impact Of Human Activity On Sedimentary Stored Carbon Levels Within A Mangrove Forest, Abigail Jones May 2014

The Impact Of Human Activity On Sedimentary Stored Carbon Levels Within A Mangrove Forest, Abigail Jones

Honors Theses

The objectives of this study were to examine the impact of human activity on organic content levels in mangrove sediment. Sediment samples and forest structure data from four sites in Utila, Honduras ranging in degradation levels were recorded and analyzed. Results indicated that forest structure differences are likely influenced more by environmental factors and setting differences than by human impacts and degradation. Additionally, the sediment from the most impacted sites had the greatest levels of organic content, while sediment from the least impacted, marine protected area, had a significantly lower average organic content level. These findings have noteworthy implications for ...


Potential Soil Nitrogen Mineralization In Biofuel Feedstock Crops With Varying Management Intensity, Brigitte Moneymaker May 2014

Potential Soil Nitrogen Mineralization In Biofuel Feedstock Crops With Varying Management Intensity, Brigitte Moneymaker

Honors Theses

In order to test whether or not in situ ion-exchange resin strips can be used as a successful indicator of soil nitrogen availability as compared to the wide-spread laboratory potential mineralization method, nine plots in the Great Lakes Bioenergy Research Center located in Hickory Corners, MI were tested using both methods. The nine plots included several different crops systems with different management intensities, such as: continuous corn, continuous corn and cover crop, rotational soybean with a cover crop, rotational corn with a cover crop, switchgrass, hybrid poplar, mixed-species native grasses, successional vegetation, and restored prairie. The two methods compared were ...

Shrub Willow Renewable Energy Environmental Benefits: Opportunities For Rural Development, Justin P. Heavey, Timothy A. Volk Jan 2014

Shrub Willow Renewable Energy Environmental Benefits: Opportunities For Rural Development, Justin P. Heavey, Timothy A. Volk

Outreach and Extension

Driven by the challenges of rural development, energy independence and environmental sustainability, research on willow biomass crops for renewable energy and environmental applications has been ongoing at SUNY College of Environmental Science and Forestry (ESF) since 1986. SUNY-ESF has teamed up with more than 20 universities, commercial partners and non-profit organizations throughout the U.S. and Canada to conduct research and facilitate the commercialization of willow biomass crops.
