PLFA Testing: The Most Powerful Tool for Understanding Soil Health

Healthy soil is the foundation of sustainable agriculture, productivity, and long-term land management. While traditional soil testing focuses on chemical nutrients, modern science now emphasizes an equally important dimension: soil biology. This is where PLFA Testing (Phospholipid Fatty Acid Analysis) becomes indispensable.
Tamilnadu Test House is proud to offer advanced PLFA testing services for agriculture, research, environmental monitoring, and soil restoration projects.

What Is PLFA Testing?

PLFA analysis identifies and quantifies the living microbial community in soil by analyzing phospholipid fatty acids present in microbial cell membranes. It provides direct, real-time insights into:
• Gram-positive bacteria
• Gram-negative bacteria
• Fungal population
• Arbuscular mycorrhizal fungi (AMF)
• Total microbial biomass and activity
This makes PLFA far more informative than conventional soil tests that highlight only nutrients and chemistry.

Why PLFA Matters:

1. True Soil Health Assessment
Microorganisms drive nutrient cycling, organic matter breakdown, and soil structure formation. PLFA reveals how active and balanced these communities are.

2. Evaluate Impact of Fertilizers & Soil Amendments
Biostimulants, compost, digestate, biofertilizers—PLFA shows how they actually influence soil biology.

3. Monitor Soil Restoration & Regenerative Farming
For industries and farms adopting sustainable practices, PLFA is the most reliable indicator of soil recovery and improvement.
