Basalt is spread on the Leverhulme Centre for Climate Change Mitigation's research cornfields in Illinois. JORDAN GOEBIG Researchers are finding that when pulverized rock is applied to agricultural fields, the soil pulls far more carbon from the air and crop yields increase. More studies are underway, but some scientists say this method shows significant benefits for farmers and the climate. BY SUSAN COSIER • SEPTEMBER 2, 2021 On a hot and humid August day near Geneva, New York, Garrett Boudinot stands in a field of hemp, the green stalks towering a foot or more over his 6-foot, 4-inch frame. Today, the mustached Cornell University research assistant will harvest six acres of the crop, weigh it in red plastic garbage bins, and continue to analyze the hundreds of water samples taken with measuring devices called lysimeters that have been buried in the field over the last three months. Boudinot, part of a research team at Cornell University, will sweat through the next two days of field
