Overview

SIST EN 15958:2012 is a European Standard developed by the European Committee for Standardization (CEN) that specifies a standardized method for the extraction of water soluble phosphorus in fertilizers. This method applies to all types of fertilizers, including compound fertilizers, where determination of water soluble phosphorus content is required. The standard ensures consistent and reliable analysis crucial for fertilizer quality control and regulatory compliance across Europe.

Key Topics

  • Scope: Defines the applicability of the method for extracting water soluble phosphorus from fertilizers.
  • Principle: Extraction by shaking fertilizer samples with water under controlled conditions.
  • Sampling and Sample Preparation: While sampling is not part of the method, EN 1482-1 and EN 1482-2 standards are referenced for sampling and preparation to ensure sample homogeneity.
  • Apparatus and Reagents:
    • 500 ml graduated flask (e.g., Stohmann flask)
    • Rotary shaker operating at 35-40 turns per minute
    • Dry pleated filter, free of phosphate contamination
    • Distilled or demineralized water at 20–25 °C
  • Procedure:
    • Weigh 5 g of laboratory sample.
    • Add 450 ml water and shake for 30 minutes.
    • Adjust volume to mark, mix, and filter.
  • Test Reporting: Includes detailed information such as sample identification, test results, date and procedure details, and repeatability results.
  • Compliance: The method supports conformity with fertilizer regulations, including European legislation on fertilizer composition.

Applications

  • Fertilizer Quality Control: Laboratories use this method to accurately measure water soluble phosphorus content in fertilizers for quality assurance.
  • Regulatory Compliance: Ensures that fertilizers meet national and European Union regulations for nutrient content, particularly phosphorus availability.
  • Agricultural Input Assessment: Helps manufacturers and suppliers verify the efficacy of phosphorus in fertilizers, supporting optimal crop nutrition.
  • Research and Development: Facilitates precise phosphorus extraction data critical for fertilizer formulation and innovation.

Related Standards

  • EN 1482-1: Fertilizers and liming materials - Sampling and sample preparation - Part 1: Sampling
  • EN 1482-2: Fertilizers and liming materials - Sampling and sample preparation - Part 2: Sample preparation
  • EN 12944-1 & EN 12944-2: Vocabulary related to fertilizers and soil improvers, ensuring consistent terminology.
  • Regulation (EC) No 2003/2003: European Parliament regulation on fertilizers, referencing analytical methods for phosphorus measurement.

SIST EN 15958:2012 plays a vital role in promoting reliable and standardized analysis of water soluble phosphorus in fertilizers, supporting both commercial and regulatory objectives within the fertilizer industry. This ensures agricultural products meet quality standards, fostering sustainable crop production through accurate nutrient management.
