The soil pollution seriously owes more than 2 times the upper limit of fertilizer use.

The fourth China Food Safety Summit Forum with the theme of "the 13th five-year Plan Food Safety Science and Technology Challenge" was held in Guangzhou a few days ago. The reporter learned from the meeting that the average use of chemical fertilizer in China far exceeded the world's recognized warning limit.

Experts attending the meeting believe that compared with the past, the quality of agricultural products in China has been continuously improved, the qualified rate of vegetable sampling inspection has shown an upward trend, and people have paid more and more attention to environmental and food safety, but the problem of soil pollution can not be ignored. In the report of the conference entitled "the impact of soil environmental pollution on the safety of edible agricultural products", experts disclosed that since 1984, the amount of chemical fertilizer (nitrogen fertilizer, phosphate fertilizer) in China has continued to increase, with an increase of about 225%, and the output per unit area has increased by 56%. The average consumption of chemical fertilizer in China is 400 kg / ha, even as high as 600 kg / ha in some areas. The average consumption of chemical fertilizer in China is more than 1.8 times of the world's recognized warning limit of 225 kg / ha, and more than 4 times that of Europe and the United States.

According to reports, the forum is led by the Guangdong Institute of Microbiology and co-hosted with the National Center for quality Supervision and Inspection of processed Food (Guangzhou), the School of Light Industry and Food of South China University of Technology, and the Food Safety and Science and Technology Research Center of Hong Kong Polytechnic University.
