C/N Ratio Formula:
From: | To: |
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.
The calculator uses the formula:
Where:
Explanation: The ratio is calculated by simply dividing the carbon weight by the nitrogen weight.
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).
Tips: Enter the carbon weight and nitrogen weight in kilograms. Both values must be > 0.
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.
