At the same time, we can design the bio organic fertilizer production business plan according to your raw material, capacity, biofertilizer type ect. So, if you are interested, please contact us.

What Raw Materials Can Be Used in Bio Organic Fertilizer Production?

Bio organic fertilizer is made from a wide variety of raw materials—many of which may already be available on your farm or in your area. Here are the most common options:

Digestate

Animal Manure

Animal waste is the most common and effective raw material in biofertilizer production. It is rich in nitrogen, phosphorus, potassium, and organic matter. Such as chicken manure, cow dung, pig manure, sheep and goat manure.

Tip: You must compost fresh manure to reduce pathogens and ammonia toxicity before them be granulated.

Biogas Residue and Digestate

Leftovers from biogas plants are high in nutrients and organic matter. On the one hand, you can use the bigestate liquid in liquid fertilizer production. On the other hand, the biogas residue is ideal for granulation after dehydration and composting.

Agriculture waste

Agricultural Waste

Crop residues and plant-based waste are excellent carbon sources that balance high-nitrogen materials. For example, wheat and rice straw, corn stalks and husks, peanut shells, soybean husks, ect.  These materials decompose slowly, so you can crush and mix them with manure or microbial inoculants to improve composting speed and quality.

Which Production Line Is Right for You: Powdered or Granular Biofertilizer?

Choosing the right form of biofertilizer depends on your budget and market.

How to make bio organic fertilizer step by step?

Step 1: Prepare Raw Materials

First, choose suitable organic materials—commonly animal manure (chicken, cow, pig), crop residues, plant waste, and kitchen waste. Among them, livestock manure is the core ingredient in most bio-organic fertilizer formulas due to its high organic content. Before composting, adjust the moisture content of manure to around 50–60% for optimal microbial activity. The manure dewatering machine is key equipment to reduce excess moisture. At YUSHUNXIN, we offer two types of solid-liquid separation equipment: screw press separators and inclined screen separators. Both models help speed up your composting process and improve fertilizer quality.

Step 2: Fermentation Composting

Fermentation is a key stage in producing high-quality bio-organic fertilizer. This process uses beneficial microorganisms to break down organic matter, eliminate harmful pathogens, and convert raw waste into nutrient-rich compost. Effective fermentation improves fertilizer quality. To meet different production needs, YUSHUNXIN offers a range of composting machines. 

  • For large-scale operations, the wheel-type compost turner handles high volumes efficiently.

  • If your facility has limited space, consider the organic fertilizer fermentation tank. It features a compact vertical design, enclosed structure, and faster fermentation cycle—ideal for urban or small-area operations.

Step 3 : Crushing Bio Compost into Fine Powder

After fermentation, compost may form lumps that are unsuitable for direct use. Crushing breaks them down into fine powder—ideally around 50 mesh—for better granulation. YUSHUNXIN offers efficient compost crushers like vertical crushers and cage mills to handle different compost textures. Proper crushing ensures uniformity and improves pellet quality in the next step. Choose the right model based on your material type and output needs.

Step 4: Granulating Bio Organic Fertilizer

Next, you can mix the composted powder with microbial agents or trace elements using a double-shaft mixer, then feed it into a granulation machine. Choose your equipment based on production needs: the drum granulator handles high-output lines efficiently, while the roller granulator lowers overall investment by using dry granulation. YUSHUNXIN provides both options to meet your scale and budget requirements.

Step 5 : Drying and cooling organic biofertilizer pellets:

After granulation, use a rotary dryer to reduce the moisture content of the biofertilizer, improving storage stability. Then, apply a rotary cooler to lower the pellet temperature, preventing caking, chemical reactions, or quality loss during storage. This step ensures your bio organic fertilizer remains durable, safe, and effective over time.

Step 6 : Coating and packaging the biological organic fertilizer:

To preserve nutrients and keep beneficial microbes active, apply a uniform layer with a biofertilizer coating machine. Then, use an automatic bagging system to pack the finished bio organic fertilizer granules. YUSHUNXIN provides both single- and double-bucket packers with high accuracy and space-saving design—ensuring tightly sealed, professional packaging that meets industrial standards and keeps your product market-ready.

What Is the Cost of Setting Up a Bio Organic Fertilizer Plant?

The investment cost for an organic bio fertilizer plant largely depends on your chosen product form—powdered or granular.

Powdered production line cost:

For powdered biofertilizer production, the basic configuration includes a compost turner, automatic loader, bio-compost crusher, rotary screener, automatic packaging machine, and belt conveyors. This setup supports efficient processing from raw material to finished fertilizer.

✅ Estimated cost: $35,000 – $100,000, depending on your desired output capacity (from 1–20 t/h).

Granular Organic Biofertilizer Production Line Cost:

A typical granular bio-organic fertilizer production line consists of: compost turner, crusher, mixer, granulator (disc, drum, or roller type), rotary dryer, cooler, screener, coating machine, packing machine, and necessary conveyors.

✅ Estimated cost: $110,000 – $580,000, depending on capacity (1–20 t/h), granulation method, and automation level.

What microorganisms used in making bio organic fertilizer?

The production of biological organic fertilizer mainly includes fermentation bacteria to promote the decomposition of materials and the addition of functional bacteria for secondary fermentation. Therefore, the selection of fermentation bacteria and functional bacteria is crucial for the production of biological organic fertilizer.

Composting microbial agents:

Fermentation bacteria are typically composed of mixed microbial strains that promote material decomposition and help eliminate odors. Commonly used types include yeast, photosynthetic bacteria, lactic acid bacteria, and actinomycetes. You can add these bacteria at the beginning of the composting process. You should select strains based on the nature of the raw materials. For instance, when composting livestock manure or straw, thermophilic bacteria such as Bacillus licheniformis and Bacillus subtilis are ideal choices due to their ability to function effectively at high temperatures.

Functional agents:

Functional bacteria refer to microorganisms that provide specific fertilizer effects in the final product. These mainly include nitrogen-fixing bacteria, phosphate-solubilizing bacteria, silicate bacteria, rhizobium bacteria, etc. After the materials are fully decomposed, you can add these composite functional strains in secondary fermentation stage. By controlling fermentation conditions, you can increase the number of beneficial live microbes in the product, thereby enhancing the overall fertilizer effect of the bio-organic fertilizer.
