Agriculture’s Role in Greenhouse Gas Emissions and Capture
Approximately 6 percent of all U.S. greenhouse gas (GHG) emissions originates from agricultural activities, according a report released by the American Society of Agronomy, Crop Science Society of America and Soil Science Society of America. These organizations reviewed GHG emissions from agricultural practices in six U.S. regions. Take a look at “Agriculture’s Role in Greenhouse Gas Emissions and Capture” to find more about long- and short-term implications of greenhouse gas emissions.

Charting New Waters: A Call to Action to Address U.S. Freshwater Challenges
“The Call to Action identifies serious challenges to the quality and supply of freshwater, such as pollution and scarcity; competing urban, rural and ecosystem water needs; climate change; environmental and public health impacts; and a variety of economic implications.”

IPNI Introduces NuGIS (Nutrient Use Geographic Information System)-A Tool for Evaluating Nutrient Use and Balance in the U.S.
Several years ago, International Plant Nutrition Institute began creating a rigorous geographic information retrieval (GIR) based model, ‘NuGIS’ for assessing nutrient balance and balance trends in the U.S. This project improves interpretation of the nutrient status of cropping systems.
Miscanthus Uses More Water, Leaches Less Nitrogen
Raising switchgrass or miscanthus may use more water but will decrease the risk of nitrogen pollution of surrounding water bodies. The research, conducted by the University of Illinois, established the positive and negative aspects of Miscanthus and Switchgrass.
Scientist Identifies Genes that Promise More Efficient and Economical Biofuel Production
With the development of a yeast strain with increased tolerance to alcohol, biofuels production may become more efficient and economical. Identifying these genes will help in producing transportation fuels from biomass more economically and efficiently.
Switchgrass Lessens Soil Nitrate Loss into Waterways, Researcher Says
Research conducted by Iowa State University revealed that application of certain conservation methods can reduce nitrogen and nitrate runoff. For the past three summers, Matt Helmers, associate professor of agricultural and biosystems engineering, and Antonio Mallarion, professor of agronomy, studied nitrate levels in different crops and types of fertilizer treatments.
