New fertilizers may be needed in the future to counteract the effect of higher carbon dioxide (CO2) in the atmosphere, which reduces crops' protein content by 20 percent, according to new research.

Researchers found that plants lose the ability to take up so much nitrate — the most common form of nitrogen in agricultural soils — and convert it into organic compounds, such as proteins, when growing in CO2-enriched environments.
