Advancing Agroecological Agroforestry: A Vermont Participatory Storytelling And Story Mapping Project, Sydney Blume

Food Systems Master's Project Reports

Agroforestry is the intentional integration of trees into agricultural landscapes. Advancing agroforestry has the potential to support just food system transition, but it must take direction from traditional approaches (culturally-embedded, millennia-old agroforestry practices in forest ecosystems) and agroecology (the movement, science, and practice for just and sustainable food and agricultural systems). An agroecological approach to agroforestry is essential to avoid agroforestry replicating the logics and harms of industrial agriculture and to encourage learning from traditional agroforestry practices, and likewise, traditional approaches to agroforestry can support a transformative agroecological transition through redesign of agroecosystems and shifting perspectives and ethics. This paper …

A Sky Island Perspective: New England Alpine Plant Distributions Across The Region, Andrea Tirrell

Electronic Theses and Dissertations

Alpine ecosystems around the globe are at risk due to climate change, human disturbance, and habitat loss. New England alpine zones are small and fragmented, which could make them vulnerable to global change. However, the persistence of tundra relics throughout the Holocene suggests the persistence of these communities in microclimate refugia. Assessing the near-term vulnerability of alpine plant communities is challenged by a lack of standardized, repeat surveys and long-term monitoring data, which presents a challenge for the many agencies monitoring New England’s alpine zones. Island biogeography theory predicts that alpine species richness is a function of area, but this …

There is growing evidence of the importance of gut health & the microbiome’s link to several aspects of health, including the immune system, mental health, and metabolic syndrome. Through collaboration with two dietitians, a "promoting gut health" patient handout was created and existing nutrition handouts were updated to reflect current dietary recommendations.

2020 Summer Annual Variety Trial, Heather Darby, Sara Ziegler, Ivy Krezinski, Rory Malone

Northwest Crops & Soils Program

Warm season grasses, such as sudangrass, and millet can provide quality forage in the hot summer months, when cool season perennial grasses enter dormancy and decline in productivity. The addition of summer annuals into a rotation can provide a harvest of high-quality forage for stored feed or grazing during this critical time. Generally, summer annuals germinate quickly, grow rapidly, are drought resistant, and have high productivity and flexibility in utilization. The UVM Extension Northwest Crops and Soils Program conducted this variety trial to evaluate the yield and quality of warm season annual grasses.

2020 Organic Spring Wheat Crosses Variety Trial, Heather Darby, Henry Blair

Northwest Crops & Soils Program

The goal of this project is to develop new spring wheat varieties that are suited for organic management in Northeast soils and climatic conditions. Most commercially available varieties are developed in regions with climates, soils, and management techniques that are very different from northern New England. These modern varieties are also genetically homogenous and inbred for uniformity, sometimes resulting in rapid breakdown of genetic resistance to local diseases. Eight crosses were developed by Dr. Stephen Jones of Washington State University, including crosses of two varieties bred by famed Vermont botanist and wheat breeder Cyrus Pringle. Of these varieties, a number …

Steam Treated Grains Trial, Heather Darby, Ivy Krezinski, Hillary Emick

Northwest Crops & Soils Program

Locally grown grains, such as wheat and barley, are in high demand in the Northeast for both livestock feed and human consumption. One major challenge that grain growers encounter is infection by fungal diseases, such as loose smut and the infection of Fusarium head blight (FHB). Loose smut appears on grains as “smutted grain heads”, which are filled with spores that appear black or brown. The spore masses replace the grain heads, so that fewer or no viable kernels are left for harvest. Smutted heads are caused by the fungal pathogen genus Ustilago. Ustilago nuda commonly infects barley, while …

Sare Interseeding Cover Crops In Corn Silage Cropping Systems, Heather Darby, Sara Ziegler, John Bruce, Lindsey Ruhl

Northwest Crops & Soils Program

With increasing focus on minimizing environmental impacts from agriculture, farmers are looking for strategies that are good for farm and environmental viability. Cover cropping is one strategy that has been promoted to help farms improve soil health and minimize soil and nutrient losses to the environment. However, with a short growing season it is often difficult to get an adequate cover cropping following corn silage harvest. Therefore, farmers are interested in using interseeding techniques to establish cover crops into an actively growing corn crop. Being successful with this practice will likely require changes to other aspects of the cropping system …

Interseeding Cover Crops Into Wide-Row Corn Silage, Heather Darby, Ivy Krezinski, Rory Malone, Sara Ziegler

Northwest Crops & Soils Program

There has been increased interest in interseeding cover crops into corn. Cover cropping is a way to prevent soil erosion, maintain and/or improve soil nutrients, improve soil aggregation, prevent nutrient loss from runoff, and increase water retention. Such soil improvements can promote conditions that add resiliency to a crop, especially considering extreme weather patterns that may affect yields. Interseeding can be beneficial by providing year-round ground coverage and maximizing a short growing season by interseeding early to allow for full cover crop growth. It can be difficult to grow a successful cover crop, given other demands from a farm operation …

Vermont Organic Silage Corn Performance Trial, Heather Darby, Ivy Krezinski, Rory Malone, Sara Ziegler

Northwest Crops & Soils Program

The University of Vermont Extension Northwest Crops and Soils Program conducted an organic silage corn variety trial in 2020 to provide unbiased performance comparisons of commercially available varieties. To determine varieties that are best suited to this production system and our region’s climate, we evaluated 9 commercially available organic corn silage varieties.
