PLFA Soil Microbial Community Analysis

Unlock the Hidden Life in Your Soil

Phospholipid Fatty Acid (PLFA) analysis reveals the living microbial community structure and biomass in your soil—giving you a precise snapshot of the biological engine driving nutrient cycling, soil health, and plant performance.

What You'll Discover:

• Bacteria – Gram-positive and Gram-negative populations that mineralize nutrients and build soil structure
• Fungi – Arbuscular Mycorrhizae (plant partners) and Saprophytes (organic matter decomposers)
• Protozoa – Microbial grazers that release plant-available nitrogen
• Undifferentiated Microbial Groups – Additional functional communities contributing to soil ecology

Why PLFA Matters

Each functional group is identified by its unique PLFA composition—the main components of living microbial cell membranes. This analysis shows how your soil's microbial community responds to plant diversity, environmental conditions (pH, moisture, temperature), soil characteristics (texture, organic matter), and management practices (tillage, cover crops, amendments).

Track Progress, Validate Practices

Compare samples across different management zones to identify shifts in microbial structure, or test the same areas annually to document soil health improvements over time. PLFA analysis provides the biological evidence that your regenerative practices are working.

Ideal For:

• Growers transitioning to regenerative or organic systems
• Farms implementing cover crops, reduced tillage, or compost applications
• Consultants and researchers tracking soil health interventions
• Anyone serious about understanding the microbial foundation of soil fertility
