ISO 17852 Soil Quality Determination of Cation Exchange Capacity: Laboratory Testing Services

The determination of cation exchange capacity (CEC) is a crucial aspect of soil quality assessment, as it provides valuable information on the ability of soils to retain and release nutrients. The International Organization for Standardization (ISO) has established the standard ISO 17852:2018 Soil Quality Determination of Cation Exchange Capacity, which outlines the procedures for laboratory testing.

Legal and Regulatory Framework

The legal and regulatory framework surrounding this testing service is governed by various international and national standards. The European Unions Water Framework Directive (2000/60/EC) requires member states to assess soil quality, including CEC determination. In addition, the EUs Soil Thematic Strategy (COM(2006) 02 final) emphasizes the importance of soil protection and conservation.

International and National Standards

The relevant international standards for ISO 17852:2018 include:

  • ISO 10390:1994 Soil quality Determination of pH

  • ISO 11465:1997 Soil quality Determination of water content using a thermogravimetric method
