Greenhouse Gas Calculator Connects Farming Practices with Carbon Credits

Web-based tool helps farmers reduce greenhouse gas losses and gain economic advantage
Greenhouse gas markets, where invisible gases are traded, must seem like black boxes to most people. Farmers can make money on these markets, such as the Chicago Climate Exchange, by installing methane capture technologies in animal-based systems, no-till farming, establishing grasslands, and planting trees.
Farmers, students, extension educators, offset aggregators, and other stakeholders need to understand how to change farming practices to maximize their potential economic returns in these new markets.
To open the black box, researchers at the W.K. Kellogg Biological Station, including Claire P. McSwiney, Sven Bohm, Peter R. Grace, and G. Philip Robertson, developed the Farming Systems Greenhouse Gas Emissions Calculator, a simple …

How Grazinglands Influence Greenhouse Gas

Study examines grasslands and grazing management impacts on global warming
Grazinglands represent one of the largest land resources in the world, yet their role as net sinks or sources of greenhouse gases is essentially unknown. Previous research has emphasized the role of grazing management on the sequestration of atmospheric carbon dioxide as soil organic carbon. However, there is a lack of information regarding how grazing management impacts the flux of two potent GHGs, nitrous oxide and methane.
A team of scientists lead by Mark Liebig at the USDA-ARS Northern Great Plains Research Laboratory estimated net global warming potential for three grazing management systems located in central North Dakota. The grazing management systems represented two native vegetation pastures …
