Shifts In N-Efficiency Of Different Farm Types In Response To Climate Change, S. Dueri, P. L. Calanca, Juerg Fuhrer
Shifts In N-Efficiency Of Different Farm Types In Response To Climate Change, S. Dueri, P. L. Calanca, Juerg Fuhrer
IGC Proceedings (1997-2023)
Climate change may affect European farms, but in contrast to individual crops - the sensitivity of whole farming systems has not been the subject of much research. At the farm level, where different farm units are linked through the availability and flow of nitrogen (N), effects on individual crops are interlinked, and through shifts in grasslands and related animal production with altered nutrient flows. Ideally, N flows into the system and N-export with products should be equal, and thus N-use-efficiency (NUE), expressed as the ratio of N export to N loss, would be maximal. The objective of this study was …
Evaluating The Economic And Environmental Sustainability Of Integrated Farming Systems, C. A. Rotz, M. A. Sanderson, M. Wachendorf, F. Taube
Evaluating The Economic And Environmental Sustainability Of Integrated Farming Systems, C. A. Rotz, M. A. Sanderson, M. Wachendorf, F. Taube
IGC Proceedings (1997-2023)
Economic and environmental sustainability has become a major concern for forage-based animal production in Europe, North America and other parts of the world. Development of more sustainable farming systems requires an assimilation of experimental and modelling research. Field research is critical for supporting the development and evaluation of models, and modelling is needed to integrate farm components for predicting the long-term effects and interactions resulting from farm management changes. Experimentally supported simulation provides a tool for evaluating and comparing farming strategies and predicting their effect on the watershed, region and beyond.
Insomniac Of The Soil: A Collection Of Poetry And Essays, Sarah E. Golibart
Insomniac Of The Soil: A Collection Of Poetry And Essays, Sarah E. Golibart
Senior Honors Projects, 2010-2019
“Insomniac of the Soil” is a homage to a landscape that has deeply informed Sarah Golibart's life and her artistic voice – the tidewater flatlands of Virginia’s Chesapeake Bay peninsula where her family lives and where Golibart has worked on farms since high school. Both her poems and essays are earthy, imagistic, and grounded – quite literally – in the soil as well as in a sensibility of ecological ethics and sustainability. “Insomniac of the Soil” is also a love song to the fervent and fallow cycles of the soil.
Trace Element Soil Contamination At Urban Community Gardens In Washington, Dc, Adam J. Long
Trace Element Soil Contamination At Urban Community Gardens In Washington, Dc, Adam J. Long
Environmental Analysis Program Mellon Student Summer Research Reports
In recent years, urban gardening has become a popular form of environmental, food, and social justice. Urban community gardens such as those in Washington, DC can reduce the environmental footprint of food production, provide access to healthy produce in “food deserts,” and provide other social, educational, and even financial benefits. However, the rising popularity of urban gardening has put many people in close contact with urban soils, which are likely to contain various contaminants due to concentrated human activity over extended periods of time. This study investigates heavy metal soil contaminants found in community gardens located in Washington, DC. 45 …
Go Farm, Goleta: Urban Agriculture Protection For Eastern Goleta Valley, Eli M. Krispi
Go Farm, Goleta: Urban Agriculture Protection For Eastern Goleta Valley, Eli M. Krispi
Master's Theses
This paper explores two potential land use planning strategies that can be used to preserve and enhance the economic viability of agricultural operations surrounded by suburban development in Santa Barbara County’s Eastern Goleta Valley: buffers between agriculture and other land uses, and agritourism. In the case of buffers, academic literature is examined to determine how effective buffers are at various tasks (filtering runoff, mitigating dust and wind, providing habitat, etc.) and how to construct buffers to maximize their effectiveness. Land use plans and codes from several California jurisdictions are studied to see how buffers are put to use. Academic literature …

Farm Nutrient Management, William O. Thom
Farm Nutrient Management, William O. Thom
Soil Science News and Views
Nutrient management is becoming a buzz word in today's vocabulary of crop and livestock production. In the past it was applied to efficient management of all nutrient sources used for crop production. More recently it is being used to account for all nutrients used for crop production that are brought onto the farm, removed from the farm in crop and animal products, and reallocated within the farm unit. Nitrogen, phosphorus, and potassium are the nutrients of concern with nitrogen and phosphorus being most important.
