China's food safety issues have always been a cause for concern. Experts from the Chinese Academy of Sciences have warned that the extensive use of chemical fertilizers and pesticides has significantly reduced the organic matter content in China's arable land, which could threaten the country's grain production.
Food safety scandals in China continue to emerge, following previous incidents such as tainted milk powder and lean meat powder. Now, experts from the Chinese Academy of Sciences have issued another warning, stating that China's heavy reliance on chemical fertilizers and pesticides has degraded the quality of its farmland and poses a threat to grain output.
Since 2007, China has become the world's largest consumer of chemical fertilizers, using approximately 1.3 million tons of pesticides annually—2.5 times the global average. Recent reports from the Chinese Academy of Sciences indicate that excessive fertilizer use has led to a decline in soil quality. Data shows that the organic matter content in the fertile farmland of northeastern China has dropped from 8%–10% in the 1950s to just 1%–5% today.
