Changing The Rock Dust Applied To Farm Fields Could Help Reduce Carbon Emissions

December 31, 1969 | ATLANTA

Agriculture is responsible for more than 10 percent of U.S. greenhouse gas emissions, according to the U.S. Department of Agriculture, and some in the industry are looking for ways to reduce their carbon footprint. One of those efforts is replacing the kind of crushed rock farmers use to neutralize their soil’s acidity, from limestone to basalt. Chris Reinhard, associate professor in the School of Earth and Atmospheric Sciences, is one of the researchers involved in the study.
