Overview

SIST EN ISO 17601:2026 is an international standard that details a method for estimating the abundance of selected microbial gene sequences in soil using quantitative polymerase chain reaction (qPCR) from DNA directly extracted from soil samples. Developed by the Slovenian Institute for Standardization (SIST) and aligned with ISO 17601:2025, this standard provides clear procedures for using DNA-based molecular techniques, specifically targeting microbial gene quantification. Such quantification serves as a reliable indicator of soil quality and microbial group presence, offering significant advantages over traditional culture-based microbiology methods.

Key Topics

Soil DNA Extraction: The standard emphasizes the extraction of DNA from both living and non-living soil biota, in accordance with ISO 11063. Proper DNA extraction is essential for accurate representation of the indigenous microbial communities.

qPCR Methodology: Detailed steps for setting up and validating qPCR assays, including amplicon design, standard preparation, calibration, and the assessment of qPCR performance parameters such as repeatability and reproducibility.

Selection of Target Genes: Guidance on choosing specific microbial gene sequences to quantify, allowing the method to target functional or taxonomic groups relevant for soil ecological assessment.

Standard and Negative Controls: Instructions for preparation of qPCR standards (including cloning and dilution steps) and negative controls (NTCs) to ensure methodological reliability and to control for contamination or assay inhibition.

Critical Process Steps: Identification of crucial points in the protocol that impact the sensitivity, specificity, and accuracy of results, such as primer design, inhibition checks, and validation procedures.

Applications

The methods described in SIST EN ISO 17601:2026 are widely applicable across various sectors that require accurate assessment of soil microbial communities:

Soil Quality Monitoring: Provides data for routine monitoring programs, enabling the analysis of changes in microbial group abundance in agricultural, environmental, or restoration contexts.

Soil Remediation and Risk Assessment: Facilitates the evaluation of the effectiveness of soil treatment, bioremediation, or pollution mitigation efforts by tracking shifts in microbial gene abundance.

Research and Development: Supports ecological and environmental studies focused on soil biodiversity, microbial ecology, and the impact of land management practices or contaminants.

Regulatory Compliance: Offers a standardized approach to DNA-based microbial quantification that supports soil assessment requirements in line with international best practices.

Related Standards

The implementation and use of SIST EN ISO 17601:2026 is supported by several related international standards, helping to ensure consistency throughout the process of soil sample collection, DNA extraction, and microbial analysis:

ISO 11063: Soil quality - Direct extraction of soil DNA

ISO 18400-206: Soil quality - Sampling - Collection, handling, and storage of soil under aerobic conditions for laboratory assessment of microbiological processes, biomass, and diversity

Other DNA-based environmental analysis standards: Complementary methods for the detection, quantification, and characterization of soil microorganisms

Practical Value

By specifying qPCR protocols for analyzing soil DNA, SIST EN ISO 17601:2026 enables laboratories, researchers, and environmental professionals to:

Achieve reliable, reproducible, and standardized estimations of microbial gene sequence abundance in soils

Support soil health assessments using robust molecular indicators

Replace or complement traditional soil microbiological methods with more sensitive, DNA-based approaches

Satisfy regulatory and scientific requirements for soil quality monitoring and reporting

Adopting this standard ensures methodological alignment across national and international projects, supporting robust data generation and comparison for soil microbial community analysis.
