Scientists Show How to Grow More Nutritious Rice That Uses Less Fertilizer

Sep 25, 2025

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.”

Part of what made the Green Revolution so revolutionary was the invention of synthetic, nitrogen-heavy fertilizers that could keep agricultural yields high. But they’re expensive to make, they create an enormous amount of carbon dioxide, and much of the fertilizer washes away.

Video: Cheapest States to Buy Farmland in America

The United States has more than 895 million acres of farmland, which includes all rural land tied to farming operations, from highly fertile Midwest cornfields to vast grazing ranges in the West, as well as the undeveloped rural land, which is often sold as ranches, homesteads, or uncultivated lots. Nowadays investing in rural land is very lucrative even billionaires like Bill Gates, Jeff Bezos, and Warren Buffett have bought up thousands of acres of farmland across America. In contrast to investors, agricultural companies, and business moguls, some buy farmland for their own requisites, like starting a small farmstead, creating a cottage, and becoming self-resilient. In this video we have ranked the top cheapest states to buy farmland according to the per-acre land value, which is accumulated from the United States Department of Agriculture. The USDA’s per-acre land values come from an annual survey, which is cross-checked with actual sales data, appraisals, and market trends to ensure accuracy. So here are The top Cheapest States to Buy Farmland.
