Evaluate Carbon-to-Nitrogen Balance for Composting Efficiency and Nutrient Value

A Key Indicator of Compost Maturity and Performance

The carbon-to-nitrogen ratio (C:N ratio) is one of the most critical indicators of compost quality. Whether you're composting livestock manure, plant residues, or food waste, the ideal C:N ratio helps determine how efficiently your compost breaks down and how well it will support soil microbial life.

This test gives you a fast, accurate measurement of the total carbon and nitrogen content in your compost sample, allowing you to fine-tune your inputs or verify that your finished product is ready for soil application.

What This Test Measures

• Total Carbon (%)
• Total Nitrogen (%)
• Carbon-to-Nitrogen Ratio (C:N) – Reported as a simple ratio value

Results help you determine if your compost is:

• Too rich in carbon(slow decomposition, low nutrient availability)
• Too high in nitrogen(risk of odor, ammonia volatilization, or burn)
• Properly balanced for microbial activity and plant-friendly release

Sample Submission Requirements

• Minimum Sample Size: 3–4 cups of finished or in-process material
• Packaging: Clean, sealed plastic bag or container
• Turnaround Time: 4- 5 business days from lab receipt

Ideal For:

• Compost producers monitoring batch consistency
• Farmers using on-farm composting systems
• Soil amendment manufacturers ensuring balanced blends
• Consultants evaluating input materials for C:N compatibility
• Organic growers optimizing microbial health and nutrient cycling
