  • Soil contamination: If the microbial biomass in soil is not within acceptable limits, it can lead to soil contamination.

  • Product safety issues: Companies that fail to conduct ISO 14240-2 testing may produce products that are contaminated with soil.

    • How to Conduct ISO 14240-2 Testing

    Conducting ISO 14240-2 testing involves the following steps:

    1. Sampling: Collect soil samples from the area of interest.

    2. Extraction: Use a fumigation extraction method to extract the microbial biomass from the soil sample.

    3. Measurement: Measure the microbial biomass extracted using techniques such as gas chromatography or mass spectrometry.

    Equipment and Supplies Needed

    The following equipment and supplies are needed for ISO 14240-2 testing:

  • Soil sampling equipment: Equipment used to collect soil samples, such as sampling tubes and corers.

  • Fumigation extraction apparatus: Equipment used for fumigation extraction, such as a sealed vessel or a fumigation chamber.

    • Quality Control and Assurance

    Ensuring quality control and assurance is critical when conducting ISO 14240-2 testing:

  • Calibration of equipment: Regularly calibrate equipment to ensure it remains accurate and precise.

  • Use of certified reference materials: Use certified reference materials (CRMs) to validate the accuracy of results.

    • Interpretation of Results

    Interpreting the results of ISO 14240-2 testing requires expertise:

  • Understanding of microbial biomass: Understand the concept of microbial biomass and its importance in soil quality.

  • Use of statistical analysis: Use statistical analysis to interpret the results of the testing.

    • ISO 14240-2 Testing Limitations

    ISO 14240-2 testing has several limitations:
