Core Viewpoint - The newly developed soil acidification adjustment technology aims to improve the "sub-healthy" state of farmland, enhancing agricultural productivity and product safety through precise soil management and tailored treatment plans [1][2][4]. Group 1: Technology and Methodology - The technology involves a comprehensive soil examination using ICP-MS to analyze 23 indicators, creating a digital soil profile [1]. - An AI-driven agricultural big data platform is utilized to customize treatment plans for each field, matching organic matter conditioners, microbial agents, and trace elements [1]. - The method reduces traditional fertilizer usage by 40% while ensuring effective fertilization management through an integrated water and fertilizer system [1]. Group 2: Results and Impact - The demonstration fields showed a significant increase in soil pH by 1.2 and a 31.06% increase in rice yield compared to conventional fertilization methods [2]. - Key economic indicators such as effective ear count, seed setting rate, and thousand-grain weight have all improved, breaking the cycle of soil acidification leading to low crop yields and poor product quality [4]. - The technology has the potential to be applied across 850,000 mu of rice fields in the county, providing a viable path for increased production and income [4]. Group 3: Future Plans and Collaboration - The team, consisting of members from various research institutions and companies, plans to continue optimizing the technology and aims to expand pilot projects nationwide [4].
