The cultivation of rice—the staple grain for more than 3.5 billion people around the world—comes with extremely high environmental, climate and economic costs.
The cultivation of rice—the staple grain for more than 3.5 billion people around the world—comes with extremely high environmental, climate and economic costs. But this may be about to change, thanks to new research led by scientists at the University of Massachusetts Amherst and China’s Jiangnan University. They have shown that nanoscale applications of the element selenium can decrease the amount of fertilizer necessary for rice cultivation while sustaining yields, boosting nutrition, enhancing the soil’s microbial diversity and cutting greenhouse gas emissions. What’s more, in a new paper published in the Proceedings of the National Academy of Sciences, they demonstrate for the first time that such nanoscale applications work in real-world conditions.
“The Green Revolution massively boosted agriculture output during the middle of the last century,” says Baoshan Xing, University Distinguished Professor of Environmental and Soil Chemistry, director of UMass’ Stockbridge School of Agriculture, and co-senior author of the new research. “But that revolution is running out of steam. We need to figure out a way to fix it and make it work.”
