Academician of the Chinese Academy of Sciences and professor at the China Agricultural University Chen Wenxin said in an interview with reporters on the 7th that the current domestic agricultural production is overly dependent on chemical fertilizers and pesticides, which not only damages the soil, reduces the quality of crops, pollutes the environment, but also greatly increases production costs for producers. And consumers create economic burdens that threaten food safety and national food security strategies.

“The area of ​​farmland in China and the United States is close, but the use of chemical fertilizers is much higher than that of the United States.” For example, she said that China's nitrogen fertilizer application amounted to 39 million tons, which is 3.3 times that of the United States. This alone has greatly increased China’s crop production costs. As a result, domestic agricultural product prices have continued to rise.

Academician Wenwen Chen told reporters that she had repeatedly made recommendations to the relevant central authorities and hoped that they could act as early as possible and take effective measures to formulate policies to encourage farmers to apply more organic fertilizers and biotechnology to reduce the use of chemical fertilizers and pesticides. Dosage, and increase support for organic fertilizers, organic pesticide production companies and biotechnology research institutions.

“A large part of the environmental pollution comes from non-point source pollution in agricultural production. Crops can only absorb a small portion of chemical fertilizers and pesticides. Most chemical fertilizers and pesticides flow into rivers, lakes and seas due to factors such as rainfall and soil erosion. As a result, the more chemical fertilizers and pesticides are used. The serious environmental pollution is also serious.” Academician Wenwen Chen stated that the combination of agricultural biotechnology and the extensive use of organic fertilizers and organic pesticides will both increase grain yield and quality and protect the environment.
