BEIJING, China (Reuters) — China is targeting zero growth in the use of chemical fertilizers and pesticides by 2020 to avoid further contamination of its farmland.
Wide use of chemical fertilizers, of which China is the biggest consumer, has boosted its agricultural output and kept the world’s most populous country largely self-sufficient in grains, but it has also threatened food safety.
“Overuse of chemical fertilizer has increased costs and damaged the agriculture ecological environment,” said Zeng Yande, a department director with the agriculture ministry.
China accounts for a little more than a fifth of the world’s total grain output, while its use of chemical fertilizer is more than a third of global consumption and equivalent to the total use by the United States and India combined.

Already facing some community pushback, a proposed 2,000-head cattle feedlot south of Swift Current, Sask., has been rejected for a municipal permit, partly over zoning concerns about the minimum distance from a residence.
Annual growth in the use of chemical fertilizers will be capped below one percent from 2015-19, it added, with no growth slated for 2020.
China’s use of chemical fertilizer grew by an average 5.2 percent a year over the past three decades, reaching 59 million tonnes in 2013, the news agency said. Its use versus output is 2.6 times that of the United States and 2.5 times that of the European Union, it said.
Zhang Fusuo, a professor at the China Agricultural University, said overuse of fertilizer is the main reason for soil acidification in China.
The country will use more organic fertilizer, currently not fully utilized, to help boost grain output, said Zeng.
