ISO 10390 Soil Quality - pH Determination Test

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of ISO 10390 testing. ISO 10390 is a standard titled "Soil quality - Determination of pH". This standard provides guidelines for pH determination in soil samples. pH is a measure of the acidity or alkalinity of a substance and is a fundamental parameter in evaluating soil quality.

The method outlined in ISO 10390 includes the following steps:

• Sample Collection: Representative soil samples are collected from desired locations following appropriate sampling protocols to ensure sample representativeness.
• Sample Preparation: Collected soil samples are air-dried and visible plant material, rocks or debris are removed. The samples are then ground and sieved to obtain a fine, homogeneous earth powder for testing.
• pH Measurement: A part of the prepared soil sample is mixed with pure water at a certain rate. The mixture is allowed to stand for a specified time to ensure proper hydration. After the waiting period, the pH of the soil-water mixture is measured using a calibrated pH electrode or indicator paper.
• Calibration and Standardization: Before testing soil samples, the pH meter or indicator paper should be calibrated using standard buffer solutions with known pH values. This provides accurate and reliable pH measurements.
• Reporting: pH values ​​obtained from soil samples are recorded and reported according to the specific reporting requirements or units specified in the standard.

ISO 10390 provides specific requirements, procedures and calculations to ensure standardized and accurate determination of pH in soil samples. The standard also contains information on the equipment, calibration and quality control measures necessary to obtain reliable results.
