🌾 What is a Bio-Digestor?

A bio-digestor is a sealed system designed to decompose organic waste in the absence of oxygen. The anaerobic environment fosters microbial activity, which breaks down organic material and transforms it into:

• Biogas: A mixture of methane (CH₄) and carbon dioxide (CO₂), usable as renewable energy.
• Bio-slurry (Jivamrut): A liquid organic fertilizer rich in essential nutrients and beneficial microbes for soil and crops.

Key Features

• Sealed environment to maintain anaerobic conditions
• Large capacity (27,000 liters) to handle significant organic waste
• Continuous or batch processing options
• Efficient conversion of waste into high-value products

💧 How a Bio-Digestor Works

Input Materials

At Manas Krishi Farms, we use fresh cow and goat dung, crop residues (stalks, leaves), kitchen and organic farm waste, and water to maintain proper moisture content. Sometimes, a starter culture of beneficial microbes is added to speed up the process.

Anaerobic Digestion Process

1. Loading the Digester: Organic waste is mixed with water and added to the anaerobic bag.
2. Microbial Activity: Anaerobic bacteria decompose the organic matter without oxygen.
3. Production of Bio-Slurry: Nutrients are released in a form easily absorbed by plants.
4. Biogas Generation: Methane is produced as a byproduct.
5. Harvesting: The bio-slurry (Jivamrut) is drained after 20–40 days and applied to soil or crops.

Scientific Notes

• Retention Time: 20–40 days for optimal decomposition
• Temperature: 30–40°C (mesophilic conditions)
• pH: Ideal 6.5–7.5
• C/N Ratio: Optimal carbon to nitrogen ratio of 20–30

🌻 Production of Jivamrut

Jivamrut is the nutrient-rich bio-slurry produced by our bio-digestor. It contains essential macronutrients such as Nitrogen (N), Phosphorus (P), and Potassium (K), beneficial microorganisms that promote soil health and suppress pathogens, and organic carbon that improves soil structure and water retention.

How We Use Jivamrut

• Soil Application: Directly applied to fields to improve fertility and microbial diversity.
• Foliar Spray: Diluted and sprayed on plants to provide nutrients and strengthen immunity.
• Integration with Other Organic Practices: Works with vermicompost, biochar, and natural pesticides for year-round organic production.

🌍 Benefits of Using a Bio-Digestor

Soil and Crop Benefits

• Improves soil fertility
• Increases soil organic carbon and moisture retention
• Strengthens plant roots and growth
• Reduces pest and disease attacks
• Supports production of nutritious, chemical-free crops

Farm Sustainability

• Converts farm waste into resources
• Minimizes chemical fertilizer use
• Supports organic certification standards
• Enables circular farming

Environmental Benefits

• Reduces greenhouse gas emissions
• Decreases pollution from untreated animal waste
• Promotes carbon sequestration

🍎 Impact on Food Production

Stronger crops with higher yield and pest resistance, nutrient-rich, chemical-free produce, continuous supply of organic fertilizer for year-round production, and enhanced farm profitability through reduced input costs and high-value organic products.

🚜 Our Process at Manas Krishi Farms

1. Collection – Gather fresh dung, crop residues, and organic farm waste
2. Preparation – Mix inputs with water and optional starter culture
3. Anaerobic Digestion – Add to the 27,000-liter bio-digestor and seal
4. Monitoring – Ensure optimal temperature, pH, and moisture
5. Harvesting Jivamrut – Drain and store for field or foliar application
6. Continuous Cycle – Maintain regular feeding and digestion cycles

🌾 Additional Information

• Integration: Works with composting, vermicomposting, and biochar.
• Scalability: Supports large-scale vegetable, fruit, and fodder production.
• Research Backing: Increases crop yield by 20–30%, enhances soil organic carbon, reduces fertilizer dependence.
• Sustainability: Promotes a closed-loop system converting waste into nutrients.
