On April 9, the 2025 annual working meeting of the "Black Soil Granary" science and technology initiative was held in Harbin, Heilongjiang Province, highlighting a series of research and application outcomes aimed at safeguarding China's black soil resources and strengthening agricultural sustainability.

Since its launch, the initiative has brought together more than 90 institutions and over 1,300 researchers. It has established an air-space-ground integrated monitoring technology system and completed the first nationwide remote sensing mapping of soil carbon and nitrogen in typical black soil regions with a spatial resolution of 10 meters.

Based on these data, the program has proposed a theory centered on stabilizing and enhancing soil fertility for the prevention and control of black soil degradation and the promotion of soil health. It has also developed a comprehensive slope-gully erosion prevention and control technology system.

Significant progress has also been made in crop breeding and agricultural equipment. A soybean intelligent breeding technology system based on solid-phase breeding chips has been established. The soybean variety "Dongsheng 22" is among the top ten soybeans cultivated nationwide, and the "Dongsheng" series of soybeans has achieved an annual cultivation area exceeding 13 million mu (approximately 8.67 million hectares). The "Honghu" series of intelligent agricultural machinery and tools has broken foreign technological monopolies. Additionally, the Fuxi Brain smart agricultural management system has been developed to support the implementation of the national smart agriculture action plan.

The initiative has also explored and summarized regionally adaptable farming models such as the "Longjiang Model" and the "Sanjiang Model."

Together, these innovative achievements have provided strong scientific and technological support for the national strategy of "storing grain in the land and storing grain in technology," ensuring the sustainable use of black soil resources.
