Overview

The PD CEN/TS 17790:2022 standard is an essential document for anyone involved in the production, quality control, and application of organo-mineral fertilizers. This standard provides a comprehensive methodology for determining the chelated micronutrient content and the chelated fraction of micronutrients in organo-mineral fertilizers through treatment with a cation exchange resin.

Key Features

• Comprehensive Methodology: This standard outlines a detailed procedure for accurately determining the chelated micronutrient content in organo-mineral fertilizers.
• Quality Assurance: Ensures that fertilizers meet the required quality standards, enhancing their effectiveness and reliability.
• Industry Compliance: Helps manufacturers and quality control laboratories comply with industry regulations and standards.
• Scientific Precision: Utilizes advanced techniques involving cation exchange resins to provide precise and reliable results.

Why This Standard is Important

Organo-mineral fertilizers play a crucial role in modern agriculture by providing essential nutrients that enhance soil fertility and crop yield. The presence of chelated micronutrients in these fertilizers is vital for the optimal growth and development of plants. Chelated micronutrients are more readily available to plants, ensuring efficient nutrient uptake and utilization.

The PD CEN/TS 17790:2022 standard ensures that the chelated micronutrient content in organo-mineral fertilizers is accurately determined, thereby guaranteeing the quality and effectiveness of these fertilizers. By following the procedures outlined in this standard, manufacturers can produce fertilizers that meet the highest quality standards, ensuring better crop performance and higher yields.

Detailed Procedure

The standard provides a step-by-step procedure for determining the chelated micronutrient content and the chelated fraction of micronutrients. The process involves treating the fertilizer sample with a cation exchange resin, which selectively binds the chelated micronutrients. The bound micronutrients are then eluted and quantified using appropriate analytical techniques.

This method ensures that only the chelated fraction of micronutrients is measured, providing a more accurate assessment of the nutrient content in the fertilizer. The use of cation exchange resins enhances the specificity and reliability of the analysis, making it a preferred method for quality control in the fertilizer industry.

Applications

The PD CEN/TS 17790:2022 standard is applicable to a wide range of organo-mineral fertilizers used in various agricultural practices. It is particularly useful for:

• Fertilizer Manufacturers: Ensuring that their products meet the required quality standards and contain the appropriate levels of chelated micronutrients.
• Quality Control Laboratories: Providing a reliable method for testing and verifying the chelated micronutrient content in fertilizers.
• Agricultural Researchers: Studying the effects of chelated micronutrients on plant growth and development.
• Farmers and Agronomists: Selecting high-quality fertilizers that provide optimal nutrient availability to crops.

Benefits of Using Chelated Micronutrients

Chelated micronutrients offer several advantages over non-chelated forms, including:

• Enhanced Nutrient Availability: Chelated micronutrients are more readily available to plants, ensuring efficient nutrient uptake.
• Improved Plant Health: Adequate supply of essential micronutrients promotes healthy plant growth and development.
• Increased Crop Yields: Optimal nutrient availability leads to higher crop yields and better quality produce.
• Reduced Nutrient Loss: Chelated micronutrients are less prone to leaching and volatilization, reducing nutrient loss and environmental impact.

Conclusion

The PD CEN/TS 17790:2022 standard is an invaluable resource for anyone involved in the production, quality control, and application of organo-mineral fertilizers. By providing a reliable and accurate method for determining the chelated micronutrient content, this standard ensures that fertilizers meet the highest quality standards, promoting better crop performance and higher yields.

Whether you are a fertilizer manufacturer, quality control laboratory, agricultural researcher, or farmer, the PD CEN/TS 17790:2022 standard is essential for ensuring the quality and effectiveness of organo-mineral fertilizers. Embrace this standard to enhance your agricultural practices and achieve optimal results.

PD CEN/TS 17790:2022

This standard PD CEN/TS 17790:2022 Organo-mineral fertilizers. Determination of the chelated micronutrient content and the chelated fraction of micronutrients by treatment with a cation exchange resin is classified in these ICS categories:

• 65.080 Fertilizers

This document specifies a method for the determination of the chelated micronutrient content and the chelated fraction of a micronutrient, in organo-mineral fertilizers, having an organic matrix based on vegetal residues (cocoa shells, grape residue, soybean residue, etc), algae extract, and animal meal (feather, bones, blood, etc) and containing UVCB, EDDHA, EDDHMA, HBED, EDDHSA micronutrients by the treatment with a cation exchange resin. The limit of determination of the chelated micronutrient content highly depends on the specific electrical conductivity of the sample, on the amount of nutrient present, and varies between 0,005 % in simple matrices with high amounts of micronutrient, and 0,5 % in more complex cases (see 9.1).
