Nitrogen is an essential nutrient for plants; limits on available nitrogen constrain how much plants can grow. This in turn affects the amount of carbon dioxide plants can absorb, which affects the global climate. Using a framework that considers interactions of carbon and nutrients, researchers have developed a new global estimate of nitrogen fixation rates.
