On Dec 5, the Institute of Agricultural Resources and Regional Planning of the Chinese Academy of Agricultural Sciences held a World Soil Day  event in Beijing, unveiling the "China Soil Profile Dataset." Yang Peng, Deputy Director of the Farmland Construction Management Division of the Ministry of Agriculture and Rural Affairs, Men Lijun, Director of the National Publishing Fund Planning and Management Office, and Liu Xianwu, Vice President of the Chinese Academy of Agricultural Sciences, delivered speeches at the event. 

Liu Xianwu highlighted the importance of leveraging the "China Soil Profile Dataset" to address major national needs, strengthen technological innovation for farmland, enhance the application of data results, expedite the formation of comprehensive soil survey results, plan the construction of major national farmland research facilities in line with international advancements, and promote rapid development in soil science through interdisciplinary advantages.

Since the 1980s, the dataset, presented in the form of county-level soil maps and tables of soil profile physicochemical properties, comprehensively reflects the status of soil resources and quality across China. The research team led groundbreaking efforts in integrating and representing soil spatiotemporal big data integration and expression methods centered on intelligent design, making China the first country among major nations to establish a nationwide, high-precision digital soil dataset with a time series. This dataset offers crucial technological backing for national tasks such as the Third National Soil Survey. 

Academicians Liu Xianlin, Liu Xu, and Fu Bojie attended the event, while Zhang Fusuo, Shen Qirong, and Zhu Tong sent congratulatory messages. Officials from the Ministry of Science and Technology, the Office of the Leading Group for the Third National Soil Survey of the State Council, relevant departments, officials from the administrative departments of the Chinese Academy of Agricultural Sciences, and related units of the institute also participated in the event.
