Elevated Carbon Dioxide in Atmosphere Trims Wheat, Sorghum Moisture Needs

Plenty has been written about concerns over elevated levels of carbon dioxide in Earth’s atmosphere, but a Kansas State University researcher has found an upside to the higher CO2 levels. And it’s been particularly relevant in light of drought that overspread the area in recent months.

“Our experiments have shown that the elevated carbon dioxide that we now have is mitigating the effect that drought has on winter wheat and sorghum and allowing more efficient use of water,” said K-State agronomy professor Mary Beth Kirkham.
