Core Viewpoint - The State Council of China has approved the draft of the "Soil Protection and Quality Improvement Law," emphasizing the integrated protection of soil quantity, quality, and ecology to ensure sustainable use [1] Group 1: Research Findings - A research team led by Professor Zhang Fushuo from China Agricultural University has published a study highlighting the importance of soil health in sustainable agriculture, indicating that approximately 1.5 tons of "invisible" grain loss per hectare is due to soil issues [1] - The study identifies "crop-soil negative feedback" as a major reason for grain loss, caused by improper management in intensive agricultural practices leading to soil health problems such as compaction, acidification, and reduced biological activity [1][5] - The team has introduced a systematic research paradigm that integrates the concept of "plant-soil feedback" into agricultural ecosystems, aiming for a synergy between high crop yields and soil health [1] Group 2: Practical Applications - The research team has developed a biocontrol microbial agent that significantly reduces the incidence of wheat base rot disease, resulting in an average yield increase of nearly 17% per acre in trials conducted in Hebei [3] - In a separate study in Shandong, the application of beneficial microbial agents led to a yield increase of approximately 30% for winter wheat, demonstrating the substantial impact of soil health on crop production [5] - The research emphasizes the need for a shift in agricultural practices from a focus on short-term yields to long-term soil health, advocating for a more holistic approach to farming that considers the ecological balance [5]
