The soil census plays a critical role in supporting China's agricultural modernization and ecological sustainability, officials and experts said. This year's World Soil Day underscored the importance of accurate soil data and information in understanding soil characteristics and supporting food security, according to the Food and Agriculture Organization of the United Nations. To ensure national food security and support high-quality agricultural development with accurate soil data, China launched the third soil survey nationwide in 2022, and has made remarkable progress, according to the Ministry of Agriculture and Rural Affairs. "The team has conducted extensive soil sampling across approximately 730 million hectares of arable land, orchards, forests, grasslands and other agricultural lands," Yang said.
