Chemical fertilizers are the main source of climate-changing gases. No country uses more of them than China, which now accounts for a third of global fertilizer use. These are mostly nitrogen fertilizers, which are produced from coal. The average Chinese farmer applies over 600 kilograms of chemical fertilizers per hectare—more than triple what the average farmer uses in Brazil and nearly five times that used in the U.S., where fertilizer use is also a growing problem.

Furthermore, only a third of the nitrogen fertilizer applied to China’s wheat and rice crops is absorbed by plants. The rest ends up in rivers or the atmosphere.

Fertilizers are responsible for numerous environmental and health calamities. Our research shows that, because of its destructive impacts on soil fertility, fertilizers are contributing to dwindling yields. Over the past 40 years, the efficiency of nitrogen fertilizers has decreased by two-thirds globally, and their distribution per hectare has increased by seven times.

Kicking the fertilizer habit will require more than a technological fix. For decades, global agricultural policies and research and extension program have focused on a “Green Revolution” model of farming (large-scale crop production), based on a narrow set of seed varieties that only produce high yields when doused with fertilizers and pesticides.
