1. What is a C/N Ratio Calculator?

Definition: This calculator determines the carbon-to-nitrogen ratio (C/N ratio) based on the weights of carbon and nitrogen.

Purpose: It helps in composting, agriculture, and environmental science to assess the balance between carbon and nitrogen in organic materials.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( \text{CNratio} \) — Carbon-to-nitrogen ratio
• \( \text{Cwt} \) — Weight of carbon (kg)
• \( \text{Nwt} \) — Weight of nitrogen (kg)

Explanation: The ratio is calculated by simply dividing the carbon weight by the nitrogen weight.

3. Importance of C/N Ratio

Details: The C/N ratio affects decomposition rates, nutrient availability, and microbial activity in soil and compost. Ideal ratios vary by application (typically 25-30:1 for composting).

4. Using the Calculator

Tips: Enter the carbon weight and nitrogen weight in kilograms. Both values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What is an ideal C/N ratio for composting?
A: For efficient composting, a C/N ratio between 25:1 and 30:1 is generally recommended.

Q2: What happens if the C/N ratio is too high?
A: High ratios (>30:1) slow decomposition as microorganisms lack sufficient nitrogen for growth.

Q3: What happens if the C/N ratio is too low?
A: Low ratios (<20:1) may lead to nitrogen loss through ammonia volatilization.

Q4: How do I measure carbon and nitrogen weights?
A: These are typically determined through laboratory analysis of your material.

Q5: Can I use this for liquid solutions?
A: Yes, as long as you know the carbon and nitrogen content by weight.
