Core Viewpoint - The article discusses the upcoming "Seventh Soil Testing Technology and Application" online conference, which will feature expert interpretations of new soil testing standards and regulations, emphasizing the importance of precise soil testing technology for high-quality farmland management and environmental monitoring [2][5]. Group 1: Conference Overview - The "Seventh Soil Testing Technology and Application" online conference is scheduled for April 2, 2026, and will include authoritative interpretations of several important soil testing standards by key authors [2][6]. - The conference aims to address the strategic importance of soil testing in the context of China's 14th Five-Year Plan, which emphasizes high-quality farmland construction and management [2]. Group 2: New Standards and Their Implications - The new standard for the determination of cadmium in soil and sediment (HJ 1426-2025) will be implemented on July 1, 2026, utilizing solid direct sampling technology to significantly improve detection efficiency and data accuracy [3]. - A new standard for measuring total carbon, nitrogen, and sulfur in soil is currently under approval and is expected to be published in 2026, filling a gap in unified detection standards and supporting soil fertility evaluation and carbon accounting [3]. - Two new standards focusing on per- and polyfluoroalkyl substances (PFAS) will establish a complementary detection system for precise quantification and rapid screening of organic fluorine, thereby enhancing the market for new pollution detection instruments [4]. Group 3: Comprehensive Revision of Monitoring Standards - The "Soil Environmental Monitoring Technical Specification" (HJ 166-2026) will undergo its first comprehensive revision in 22 years, set to be implemented on June 1, 2026, optimizing the entire monitoring process and aligning with new soil environmental management requirements [5].
