Nutrient Leaching From Compost: Implications For Bioretention And Other Green Stormwater Infrastructure, Stephanie Hurley, Paliza Shrestha, Amanda Cording
Nutrient Leaching From Compost: Implications For Bioretention And Other Green Stormwater Infrastructure, Stephanie Hurley, Paliza Shrestha, Amanda Cording

This work is made available under the terms of the Creative Commons Attribution 4.0 International license,. Compost is often used as a soil amendment in gardens, agricultural fields, and other landscaped systems to alter soil biophysical characteristics and increase availability of valuable nutrients including nitrogen (N), phosphorus (P), and carbon (C). However, leaching of soluble nutrients from compost is of concern, particularly in wet settings, such as within green stormwater infrastructure, riparian areas, and floodplains. This research highlights the importance of saturation as an influencing factor on the nutrient leaching potential of different composts and compost-amended bioretention soils. Nutrient leaching …
Addressing Climate Change Impacts On Agriculture And Natural Resources: Barriers And Priorities For Land-Grant Universities In The Northeastern United States, Daniel Tobin, Rama Radhakrishna, Allison Chatrchyan, Shorna B. Allred

Climate change has serious implications for agricultural production, natural resource management, and food security. In the United States, land-grant universities and the U.S. Cooperative Extension System have a critical role to play in conducting basic and applied research related to climate change and translating findings into meaningful programming. However, land-grant universities and Extension have had difficulty maintaining their roles as the preeminent source of trusted information on complex topics like climate change. To help guide research and programming agendas of land-grant universities, the authors explored the barriers and priorities that researchers and Extension personnel at 16 northeastern land-grant universities perceive …
Effect Of Drive Row Ground Covers On Hop (Rosales: Cannabaceae) Yard Arthropod Pests In Vermont, Usa, L. Calderwood, J. Cubins, D. Vesty, H. Darby
Effect Of Drive Row Ground Covers On Hop (Rosales: Cannabaceae) Yard Arthropod Pests In Vermont, Usa, L. Calderwood, J. Cubins, D. Vesty, H. Darby

Alternatives to pesticides are necessary for the management of hop (Humulus lupulus L.) arthropod pests. The three major arthropod pests in northeastern US hop production include two-spotted spider mite, Tetranychus urticae Koch, hop aphid Phorodon humuli (Schrank), and potato leafhopper, Empoasca fabae Harris. This 3-yr study (2012-2014) in Vermont investigated the effect of flowering ground covers on arthropod pest abundance. Hop cultivars 'Nugget' and 'Cascade' were evaluated under a strip-split plot experimental design. Ground cover treatments included 1) Control: mowed red clover (Trifolium pratense) and resident weeds, 2) Clover: red clover, and 3) Diverse: common yarrow (Achillea millefolium), beebalm (Monarda …
The Use Of Extrafloral Nectar In Pest Management: Overcoming Context Dependence, Ian Matthew Jones, Suzanne Koptur, Eric J. Von Wettberg

Extrafloral nectar (EFN) provides plants with indirect defence against herbivores by attracting predatory insects, predominantly ants. Decades of research have supported the role of EFN as an effective plant defence, dating back to Thomas Belt's description of ants on acacia in 1874. Despite this extensive body of literature, knowledge of the ecological role of EFN has rarely been applied in the field of pest management. We review the existing literature on the use of EFN in agriculture and consider the obstacles that have hindered this transition. Chief among these obstacles is the influence of ecological context on the outcome of …

The reintegration of crop and livestock systems within the same land area has the potential to improve soil quality and reduce water and air pollution, while maintaining high yields and reducing risk. In this study, we characterize the degree to which federal policies in three major global food production regions that span a range of socioeconomic contexts, Brazil, New Zealand, and the United States, incentivize or disincentivize the use of integrated crop and livestock practices (ICLS). Our analysis indicates that Brazil and New Zealand have the most favorable policy environment for ICLS, while the United States provides the least favorable …
Harnessing Local Strength For Sustainable Coffee Value Chains In India And Nicaragua: Reevaluating Certification To Global Sustainability Standards, Dagmar Mithöfer, V. Ernesto Méndez, Arshiya Bose, Philippe Vaast
Harnessing Local Strength For Sustainable Coffee Value Chains In India And Nicaragua: Reevaluating Certification To Global Sustainability Standards, Dagmar Mithöfer, V. Ernesto Méndez, Arshiya Bose, Philippe Vaast

Coffee is generally grown in areas derived from forest, and both its expansion and management cause biodiversity loss. Sustainability standards in coffee are well established but have been criticized while social and environmental impact is elusive. This paper assesses the issue-attention cycle of coffee production in India and Nicaragua, including producer concerns and responses over time to concerns (sustainability standards, public regulations and development projects). Systematic comparison of the socioeconomic, environmental and policy context in both countries is then used to explore potential effects of sustainability standards. Results show limits, in local context, to relevance of global certification approaches: in …
Integrating Agroecology And Participatory Action Research (Par): Lessons From Central America, V. Ernesto Méndez, Martha Caswell, Stephen R. Gliessman, Roseann Cohen

The last decade has seen an increasing advancement and interest in the integration of agroecology and participatory action research (PAR). This article aims to: (1) analyze the key characteristics and principles of two case studies that integrated PAR and agroecology in Central America; and (2) learn from the lessons offered by these case studies, as well as others from the literature, on how to better integrate PAR and agroecology. Key principles identified for effective PAR agroecological processes include a shared interest in research by partners, a belief in collective power/action, a commitment to participation, practicing humility and establishing trust and …
