The Center for Quality Supervision and Testing for Microbial Fertilizers and Mushroom Spawn of the Ministry of Agriculture and Rural Affairs of China (formerly known as the Ministry of Agriculture of China) was established in December 1995. It is the only microbial fertilizer and mushroom quality inspection agency authorized by the Ministry of Agriculture and China Metrology Accreditation.

The center is mainly responsible for the quality safety testing and application effect evaluation of microbial fertilizers (including microbial inoculants), mushroom spawn and products in China, and provides authoritative reports and precise technical services such as reports on product quality inspection, strain identification, mushroom spawn identification, safety evaluation, environmental effect evaluation, and agricultural product quality evaluation.

Engaged in research and formulation on standards as well as research on new quality inspection technologies, the center has established the original microbial fertilizer standard system all over the world, guided and promoted the development of China’s microbial fertilizer and mushroom industry, and carried out cutting-edge research on agricultural microbial mechanisms and ecology, which provides technical support for the research and development, promotion and application of new technology products in China's microbial fertilizer industry.

In addition, the center undertakes industry supervision and technical training consultation, promotes the improvement of the technical level of the microbial fertilizer industry, and boosts the large-scale use of microbial fertilizers in the improvement of soil fertility, improvement of fertilizer utilization, increase in agricultural output, high quality products, reduced costs, and  environmental improvements.

The center contains a microbiological testing room, a mushroom spawn identification and safety evaluation room, a physicochemical testing room, and a molecular biology testing room. It has more than 100 sets of equipment, and 27 specialists in microorganisms, mushroom, biochemistry, chemical analysis and other fields.
