Core Insights - The Wuxi Market Supervision Administration released the results of the quality supervision and spot check of fertilizer products (phosphate and compound fertilizers) for the year 2025, indicating a non-conformity rate of 10% from a total of 20 batches tested, with 2 batches failing the quality standards [3]. Group 1: Quality Inspection Results - A total of 20 batches of fertilizer products were sampled, with 2 batches found to be non-compliant, resulting in a non-conformity rate of 10% [3]. - Specific non-compliance issues included the presence of chloride ions in products not labeled as containing chlorine and insufficient quality percentages of effective phosphorus and water-soluble phosphorus [8]. Group 2: Consumer Guidance - Consumers are advised to choose well-known domestic or provincial brands to facilitate accountability in case of issues and to avoid low-priced products that may contain inferior raw materials [4]. - Packaging should be checked for proper labeling, including fertilizer registration number, production standards, and quality certificates, to ensure product authenticity [4]. Group 3: Usage Recommendations - Overuse of fertilizers does not necessarily lead to increased crop yields and can harm soil health, leading to issues such as soil compaction and reduced microbial activity [5]. - The optimal time for fertilizer application is just before rain, as moisture helps in the dissolution and absorption of nutrients in the soil [6].
