According to Sinochem New Network, on December 27, the Third Forum on the Development of Potassium Humate Compound Fertilizer Industry was held in Xi’an. Experts from various sectors including politics, economics, industry, academia, and research exchanged in-depth views on soil and fertilizer civilization, innovative technologies, **standards, and industrial practices, and identified the key directions for the development of the potassium humate compound fertilizer industry. Zeng Xiancheng, honorary president of the China Humic Acid Industry Association, pointed out that the potassium humate compound fertilizer industry represents a new form of productive force that supports the strategy of \"storing grain in the land and in technology\" and helps to strengthen the foundations of food security. It should act as a guardian of both the \"red lines for arable land\" and those related to soil fertility, be a pioneer in the use of this new form of productive force in the field of green agricultural inputs, and uphold the ecological concept of harmony between soil and fertilizers. Ma Changbao, the chief agronomist at the Center for the Supervision and Protection of Cropland Quality and Farmland Engineering under the Ministry of Agriculture and Rural Affairs, affirmed the value of humic acid in addressing soil acidification and salinization as well as in improving soil fertility. He emphasized that the industry needs to bring together efforts from governments, research institutions, educational institutions, and enterprises in order to promote the sustainable development of the humic acid fertilizer industry. Xu Minggang, an academician of the Chinese Academy of Engineering, pointed out that humic acid is a key factor in assessing soil quality; it possesses multiple functions as a soil conditioner, a fertilizer enhancer, and a plant growth stimulant. By combining humic acid with potassium, it is possible to improve the utilization of potassium nutrients while also improving and enriching the soil. Huang Zhanbin, a professor at China University of Mining and Technology (Beijing), explained that relevant data show that potassium humate can increase the utilization rate of potassium fertilizers by 5% to 10%, making it a model of green and efficient product in the era of \"Fertilizer 4.0\". In addition, Li Rong, vice president of the China Humic Acid Industry Association, proposed a new development model for the \"harmonious integration of soil and fertilizers\" industry. At the meeting, Zhang Caifeng, executive deputy director of the Humic Acid Quality Testing Center (Taiyuan) of the China Humic Acid Industry Association, provided an explanation of the newly released standard **GB/T 33804—2025 Fertilizer-grade Potassium Humate**. Zhang Caifeng said that this standard replaces the old version and classifies key indicators, marking a new stage of standardization and regularization for the humic acid industry. Yan Donghao, director of the Center for the Supervision and Protection of Farmland Quality and Farmland Engineering at the Ministry of Agriculture and Rural Affairs, officially presented the results of the \"100-county demonstration trial project on potassium humate fertilizers.\" This project lasted for 5 years and covered 105 test sites in 20 provinces. Test data show that the soil organic matter in the project area increased by an average of 11.91%, the pH value of acidic soils rose by an average of 5.88%, and the average yield increases for grain and cash crops were 6.95% and 11.28% respectively; at the same time, the quality of the crops improved as well. Yang Jinchang, president of Radome Technology Group Co., Ltd., explained that the company, in collaboration with the Monitoring and Protection Center for Cultivated Land Quality and Farmland Engineering under the Ministry of Agriculture and Rural Affairs, spent 5 years carrying out the \"Hundred Counties Demonstration Project,\" which yielded significant economic and ecological benefits.
