Chinese scientists have unveiled significant technological breakthroughs aimed at combating the degradation of black soil and advancing modern agricultural development through precision farming practices.
The findings were published by the Chinese Academy of Sciences (CAS) on Monday in Nanjing, highlighting the ongoing success of the Black Soil Granary program. This major initiative was launched in 2021 in collaboration with regional authorities in Heilongjiang, Jilin, Liaoning, and parts of the Inner Mongolia Autonomous Region to provide scientific and technological support against soil degradation.
Often referred to as the giant panda of cultivated land due to its high fertility and scarcity, China black soil spans approximately 1.09 million square kilometers. This vital agricultural resource is responsible for producing roughly a quarter of the country total grain output, making it a cornerstone of national food security. However, years of intensive cultivation, historical over-exploitation, and the compounding impacts of climate change have led to varying degrees of soil degradation across the region.
To address this critical issue, the CAS research team developed a comprehensive system integrating multi-source data from satellite, aerial, and ground-based platforms. This monumental effort resulted in the creation of the first-ever information map detailing organic matter content in black soil regions at a 10-meter spatial resolution.
The newly developed mapping technology reveals spatial and temporal changes in soil degradation over the past four decades. It also clarifies the underlying mechanisms of degradation and fertility improvement, enabling the development of targeted conservation technologies tailored to specific regional conditions. This data provides crucial decision-making support for agricultural operations, including straw incorporation, precise fertilization, and soil improvement scheduling.
Zhang Yucheng, a senior engineer at the CAS Institute of Computing Technology, noted that third-generation Honghu new-energy unmanned smart tractors and supporting equipment have been widely deployed in these regions. The research team has independently developed this smart agricultural machinery technology system, with over 90 percent of its key components produced domestically. To date, 375 units of smart agricultural machines have been manufactured, including 140 soil-testing robots and 5 unmanned soil-testing transport vehicles.
Experts emphasize that the next phase of development will focus on transitioning these achievements from localized demonstrations to long-term, region-wide adoption. By leveraging the newly created black soil information map and intelligent machinery, authorities aim to build a comprehensive, digital, full-chain black soil health management system.
Future efforts will continue to iterate intelligent agricultural machinery, expanding the range of equipment to accommodate different plot sizes and soil types. This strategy is designed to drive the normalized, widespread adoption of smart farming technologies across China critical agricultural zones, ensuring long-term food security and sustainable land management.
