BS 5551-4.1.4:1984, ISO 7408-1983

Overview

BS 5551-4.1.4:1984, in conjunction with ISO 7408:1983, provides a comprehensive methodology for the determination of ammoniacal nitrogen content in fertilizers. This standard is particularly relevant in agricultural practices where accurate nitrogen measurement is crucial for soil health and crop yield. The titrimetric method outlined in this standard enables the reliable assessment of ammoniacal nitrogen even in the presence of other substances that may release ammonia when treated with sodium hydroxide.

Key Requirements

The standard specifies the procedures and conditions necessary for the accurate determination of ammoniacal nitrogen. Key requirements include:

• Sample Preparation: Proper preparation of samples is essential to ensure accurate results.
• Reagents: Use of specific reagents, including sodium hydroxide, is mandated to facilitate the titration process.
• Titration Procedure: The standard outlines a detailed titration procedure, including the necessary calculations for determining ammoniacal nitrogen content.
• Calibration: Regular calibration of equipment is required to maintain accuracy and reliability of results.

Implementation Benefits

Adhering to BS 5551-4.1.4:1984 offers several practical benefits for compliance professionals and agricultural practitioners:

• Accuracy: The titrimetric method provides a high level of accuracy in nitrogen determination, which is critical for effective fertilization strategies.
• Consistency: Following a standardized method ensures consistent results across different laboratories and testing facilities.
• Regulatory Compliance: Compliance with this standard helps agricultural businesses meet regulatory requirements related to fertilizer quality and environmental protection.
• Improved Crop Management: Accurate nitrogen measurement aids in the formulation of appropriate fertilization plans, enhancing crop yield and sustainability.

Compliance Value

Compliance with BS 5551-4.1.4:1984 is essential for businesses involved in the production and distribution of fertilizers. This standard not only ensures that products meet quality specifications but also enhances the credibility of manufacturers in the marketplace. By implementing the methodologies outlined in this standard, companies can:

• Enhance Product Quality: Regular testing and adherence to the standard improve the overall quality of fertilizers.
• Mitigate Risks: Accurate nitrogen content determination reduces the risk of over-fertilization, which can lead to environmental issues.
• Build Trust: Demonstrating compliance with established standards fosters trust among customers and regulatory bodies.

In summary, BS 5551-4.1.4:1984 is a vital standard for the agricultural sector, providing a reliable method for determining ammoniacal nitrogen content in fertilizers. Its implementation not only supports compliance with regulatory requirements but also enhances agricultural practices through improved product quality and environmental stewardship.
