Overview
CEN/TS 17777:2022 is a comprehensive European Technical Specification developed by CEN that outlines standardized methods for the determination of specific elements in organic and organo-mineral fertilizers. This document provides essential references for testing total and water-soluble elemental contents, ensuring compliance with Regulation (EU) 2019/1009 governing fertilizing products in the European market. It focuses on accurate identification and quantification of macro- and micro-nutrients, as well as potentially harmful trace elements, supporting safety, quality, and regulatory adherence.
This standard applies primarily to fertilizers classified under product function categories (PFC) 1(A) and 1(B), which include organic and organo-mineral fertilizers or their components, but excludes blends that have not been validated.
Key Topics
Total Element Content Determination
The standard references methods for measuring total concentrations of key nutrients and trace elements including:- Phosphorus (P)
- Potassium (K)
- Calcium (Ca)
- Magnesium (Mg)
- Sodium (Na)
- Sulphur (S)
- Essential trace metals such as Boron (B), Cobalt (Co), Iron (Fe), Manganese (Mn), Molybdenum (Mo), Copper (Cu), Zinc (Zn)
- Potentially hazardous elements like Arsenic (As), Cadmium (Cd), Chromium (Cr), Mercury (Hg), Nickel (Ni), and Lead (Pb)
Water-Soluble Element Content Determination
Critical for assessing nutrient bioavailability, methods for testing water-soluble forms of phosphorus, potassium, calcium, magnesium, sodium, sulphur, and various trace metals are included.Specialized Phosphorus Fractions
Techniques for determining phosphorus soluble in neutral ammonium citrate and formic acid are specified, offering insights into phosphorus availability and fertilizer efficacy.Referenced Test Methods
Methods are linked to specific CEN/TS documents detailing extraction techniques (water, aqua regia, formic acid), digestion procedures, and analytical techniques such as Inductively Coupled Plasma Atomic Emission Spectroscopy (ICP-AES).
Applications
Regulatory Compliance
Enables manufacturers, testing laboratories, and regulatory bodies to verify that organic and organo-mineral fertilizers comply with EU safety and quality criteria, especially as per Regulation (EU) 2019/1009.Nutrient Profiling
Provides standardized analytical approaches to assess nutrient content and availability, guiding fertilizer formulation and optimization to improve crop performance.Quality Control and Safety
Helps detect harmful heavy metals and metalloids to safeguard soil quality and prevent contamination, critical for sustainable agriculture and environmental protection.Research and Development
Facilitates reproducible data collection for product innovation and performance evaluation of fertilizing materials in the agricultural sector.
