Overview
ISO 8157:2022 is an international standard published by the International Organization for Standardization (ISO) that provides a comprehensive vocabulary for fertilizers, soil conditioners, and beneficial substances. This third edition, released in September 2022, defines crucial terms related to fertilizers, soil improvers, growing media, inhibitors, and plant biostimulants. It aims to standardize terminology across the agriculture and horticulture industries, promoting clear communication and consistent understanding worldwide.
The standard is developed by ISO Technical Committee ISO/TC 134, dedicated to fertilizers, soil amendments, and beneficial substances. It replaces the previous edition ISO 8157:2015, with updates reflecting recent developments such as the inclusion of terms related to plant biostimulants.
Key Topics
ISO 8157:2022 covers an extensive range of definitions segmented into several categories:
Applications
ISO 8157:2022 plays a vital role in supporting:
- Agricultural Production: By standardizing fertilizer terminology, it enhances the development, regulation, marketing, and application guidance of fertilizers and soil conditioners, helping optimize plant nutrition and crop yield.
- Regulatory Compliance: Facilitates harmonized definitions for regulatory authorities worldwide to ensure product labeling and quality control meet recognized standards.
- Research and Development: Provides a unified vocabulary to support research on fertilizer formulations, nutrient dynamics, and soil health interventions.
- Environmental Management: Encourages clear understanding of beneficial substances and inhibitors which help improve nutrient use efficiency and reduce environmental impacts such as nutrient runoff and greenhouse gas emissions.
- Trade and Communication: Assists manufacturers, suppliers, agronomists, and farmers in clear and precise communication, helping to avoid misunderstandings in international trade and product use.
