Soil metabolomics: Deciphering underground metabolic webs in terrestrial ecosystems

Area of Science:

• Environmental Science
• Biogeochemistry
• Microbiology

Background:

• Soil metabolomics is an emerging field for profiling small molecules (metabolomes) in soil.
• Soil metabolites are crucial nutrients (N, P, S) linked to microbial-driven biogeochemical cycles.

Purpose of the Study:

• To provide an overview of soil metabolomics methods and applications.
• To highlight the role of metabolomics in understanding soil nutrient cycling, carbon dynamics, and microbial interactions.

Main Methods:

• Review of current analytical techniques for soil metabolite profiling.
• Case studies on metabolomics applications in soil carbon cycling, sequestration, and stress response.

Main Results:

• Metabolomics offers novel insights into soil microbiome-metabolome relationships.
• It reveals how soil metabolomes respond to environmental changes and plant stresses.
• Applications include studying soil carbon sequestration and element biogeochemical cycles.

Conclusions:

• Soil metabolomics is a powerful tool for assessing soil function and health.
• Further research is needed to fully understand drivers of soil health using metabolomics.
