Bio organic fertilizer can improve soil vitality and crop quality. Usually, you can choose organic waste such as livestock manure, straw and biogas residue to produce bio organic fertilizer. When you setup a bio organic fertilizer production line, you need to go through several stages of preparing raw materials, fermentation, crushing, granulation, dryinga and cooling, and packaging. YUSHUNXIN will provides you the right biological fertilizer making machine in each steps. 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:
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.
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.
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.
Our team can help you choose the right composting solution based on your plant size and raw materials. Welcome to consult us!
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.

3. Making bio organic fertilizer from spent mushroom substrate
Of course, you also can use the spent mushroom substrate (SMS) as organic biofertilizer. First, mix the mushroom compost waste with animal manure and lime in a certain proportion. Then, The next steps are the same as other raw materials. After crushing and screening the spent mushroom compost, choose a suitable granulation machine according to the output. However, the waste mushroom substrate is usually alkaline, and you need to add some acidic substances such as sulfuric acid, nitric acid, phosphoric acid, etc. to lower its pH value. In this way, you can make efficient use of SMS.
How to make your own humic acid organic biofertilizer?
The humic acid organic biofertilizer manufacturing process is easy. First, compost and ferment the organic waste and related auxiliary materials. Add the biological humic acid powder to the compost in proportion. After fermentation, in order to ensure the activity of functional bacteria and humic acid, you need to dry it in low-temperature. Then, crush and creen the dried compost into powder. Next, use a dry granulation machine (roller compactor granulator) to pelletize, and then sieve out qualified finished products for packaging.
The coommon raw material of humic acid organic biofertilizer includes main ingredients, auxiliary materials and biological fulvic acid (BFA) powder. The common main material : cow dung, chicken manure, sugar factory filter mud, grass peat, etc. Auxiliary materials mushroom residue, phosphate rock powder, straw powder, etc. In additional, for improving the humic acid bio organic fertilizer, you can dd 1%-2% urea, 3%-5% superphosphate (calcium magnesium phosphate fertilizer should be added for acidic materials), and 1.5%-2% potassium chloride.
What microorganisms used in making bio organic fertilizer?
Microbial agents play an important role in the production of bio organic fertilizers. Generally speaking, bio fertilizer manufacturer use two categories according to their functions and addition time: composting microbial strains and functional agents.
Composting microbial agents:
In the process of bio organic fertilizer composting, composting microbial strains are generally added. It usually includes: photosynthetic bacteria, penicillium, yeast, Bacillus subtilis, etc. They can promote the decomposition and transformation of organic matter, improve composting efficiency, and increase the nutrient content of organic biofertilizers.
Functional agents:
To prevent high temperature from killing functional bacteria, you need to add functional bacteria after composting. Commonly used functional agents are: silicate bacteria, pseudomonas, potassium-soluble，rhizobium bacteria, etc. These can supplement the nutrients lacking in bio organic fertilizers and have different effects in the production process of bio fertilizers. You can choose according to your needs.
