The fermentation process is the core of bio-organic fertilizer production lines, directly determining product quality. Below is a deep dive into the key factors affecting fermentation and practical adjustment strategies. These will help producers fine-tune their process and boost product competitiveness.

1.The Science of Carbon-to-Nitrogen Ratio (C/N)

Best Range: 25-30:1

Adjustments: Add urea or livestock manure if C/N is too high (>35). Mix in straw or sawdust if C/N is too low (<20).

2.Getting Moisture Right

Ideal Range: 50-60%

How to Adjust: Add rice husks or mushroom residue if too wet. Spray bacterial solution or water if too dry.

3.Optimizing Airflow and Oxygen

Key Metric: Maintain oxygen >5%

Improvements: Use trough composting with automatic compost turning machines. Keep pile height between 1.2-1.5 meters. Install oxygen sensors for smarter ventilation.

4.Managing Temperature Changes

Best Range: 55-65°C (high-temperature phase)

Key Practices: Measure temperature 3 times daily, track the curve. Turn the pile immediately if it exceeds 70°C to cool down. Use wireless temperature monitoring systems.

5.Choosing the Right Microbial Starter

Best Option: Use a blend (bacteria + fungi + actinomycetes). Keep inoculation rate between 0.1-0.3%.

Mastering these fermentation control techniques will make a qualitative leap for any bio-organic fertilizer production line.
