Abstract:The region of black soil in Northeast China is the "ballast stone" of national food security. However, the degradation of black soil leads to a decline of soil fertility and ecological service function, which threatens the national food security and regional ecological security. With advance design and scientific demonstration, the Chinese Academy of Sciences (CAS) together with provinces of Northeast China launched the "Science and Technology (Sci-Tech) Battle of Black Soil Granary" by gathering outstanding scientists, high technology and equipment. At present, the CAS is planning to initiate the Strategic Priority Research Program called "Black Soil Granary", establish the State Key Laboratory of Black Soil Conservation and Utilization, and construct specialized research teams of black soil conservation and reasonable utilization. Through these measures, we aim to invigorate the Sci-Tech innovation, ensure the sustainable use of black soil, and make a strategic Sci-Tech contribution to the national food security.
