Summary
This chapter provides a comprehensive overview of soil metagenomics as a tool for understanding microbial diversity and ecological function in terrestrial ecosystems. Unlike traditional culture-dependent methods, metagenomics enables direct analysis of DNA from soil samples to characterise bacteria, archaea, fungi and viruses, revealing how soil microorganisms influence carbon, nitrogen and phosphorus cycling, organic matter degradation, bioactive compound production, and contaminant remediation. The paper argues that metagenomics is essential for monitoring and managing soil sustainability in response to agricultural practices, environmental change and climate pressures.
Regional applicability
The methodological principles described have global applicability, including to United Kingdom agricultural and soil management contexts. However, the abstract does not specify whether regional case studies or UK-specific applications are included; transferability of any findings would depend on the full chapter's content and the specific soil types and farming systems discussed.
Key measures
Microbial community composition, functional gene identification, metabolic pathways, microbial responses to environmental factors (agricultural use, contamination, climate change)
Outcomes reported
The paper presents soil metagenomics as a methodological approach to characterise microbial diversity and functional genes in soil ecosystems. It describes how metagenomics reveals microbial influences on key biogeochemical cycles and soil health indicators under various environmental and agricultural conditions.
