Main raw material of liquid biofertilizer production

What is process of the organic liquid biofertilizer production technology?

Organic liquid biofertilizer production technology adopts anaerobic fermentation and has strict requirements on the production process. The following is the liquid organic biofertilizer production process:

The first step in organic liquid biofertilizer production is the separation of manure solids from liquids. You can get liquid manure in two ways. If you want to start bio organic liquid fertilizer production fast, you can use an animal manure dewatering machine. It separates liquid from solid manure quickly. If you want to reduce investment, you can build a manure sedimentation tank to save costs.

To improve the quality of liquid organic fertilizer, you need to filter impurities after separation. A manure liquid filter system removes particles and solids. YUSHUNXIN double filtration device can filter impurities between 38-250µm. This ensures cleaner liquid biofertilizer material for the next step.

After filtration, the liquid still contains harmful bacteria and pests. To make safe liquid biofertilizer, you need sterilization. YUSHUNXIN uses UV sterilizers on the production line. The system achieves up to 99% sterilization rate and makes the fertilizer safe for crops.

The next step is fermentation. An anaerobic fermentation tank turns manure liquid into bio organic liquid fertilizer within 3-5 days. At this stage, you can add brown sugar or molasses with an ingredient tank. These materials promote microbial activity and speed up fermentation.

After fermentation, you can make customized liquid biofertilizer. YUSHUNXIN additive mixing tanks allow you to add microbial agents and nutrients such as NPK powder and humic acid. Common microorganisms include lactic acid bacteria, phosphate-solubilizing bacteria, and potassium-solubilizing bacteria. The mixing process takes about 2 hours and produces uniform, nutrient-rich liquid fertilizer.

Packaging is the last step in liquid bio organic fertilizer manufacturing process. YUSHUNXIN provides semi-automatic and automatic liquid fertilizer filling  machines. The system integrates filling and labeling. You can pack fertilizer in 500ml–5L bottles for retail sales or in 5L–200L barrels for bulk distribution. The machines are efficient and flexible for different market needs.

How to make liquid npk biofertilizer?

  • To produce NPK liquid bio – fertilizer, you should prepare the N,P,K material in advance. It doesn't matter if your raw material is ore, YUSHUNXIN's crusher can process it into powder.
  • Then, the dynamic batching machine will put them accurately according to your bio NPK liquid fertilizer formulations, such as 15 0 0 liquid fertilizer, 10 30 10 liquid fertilizer.

  • Next, Add water and biological agents to the mixture and let them react in a liquid chelating tank.
  • After the reaction, you can filter the liquid to get pure npk liquid biofertilizer.

  • Finally, package it into various sizes with a fully – automatic filling machine for sale.

For liquid fertilizer suppliers with limited budgets, making npk liquid biological fertilizer is a wise choice. Welcome to contact us !

Can you provide fish residue liquid biofertilizer production technology?

Among different liquid biofertilizer production technologies, making fertilizer from fish residue is very efficient. The first step is grinding fish residue into fine particles. This speeds up enzymatic reactions and ensures even mixing with additives such as microbial agents and trace elements. YUSHUNXIN recommends the double-shaft grinder. It uses two rotating knife rollers to tear, shear, and squeeze the material. In this way, fish residue is quickly reduced to small particles, which are suitable for producing fish protein liquid biofertilizer.

After crushing, you can add water to the fish residue. Then carry out steam sterilization, cooling, chelation, filtration, and final filling. In the chelation tank, you can add microbial agents to enhance the efficiency of liquid biofertilizer. With these steps, you can produce high-quality fish residue liquid fertilizer for commercial application.

what is the cost of establishing a liquid bio fertilizer plant?

The cost of setting up a liquid biofertilizer production factory depends on your daily capacity, equipment complexity, and automation level. Below is a breakdown by production scale:

Estimated Cost: $10,000–$50,000

This setup is ideal for farms, agri-cooperatives, or startups aiming to process small batches of organic liquid fertilizer. It typically includes: 5–10m³ anaerobic fermentation tank, basic pre-treatment: filtering, pH adjustment, manual or semi-auto mixing  and  filling machine.

Compatible with raw materials like cow urine, EM waste, or fish residue…

Estimated Cost: $60,000–$12,000

We designed the bio liquid fertilizer unit for regional biofertilizer suppliers and medium-sized farms. Its configuration include: 15–30m³ fermentation tanks with temperature & pH monitoring, inline dosing systems for microbial strains (e.g., Bacillus subtilis, EM), two-stage filtration to remove impurities and enhance product clarity, semi-automatic filling line (1–20L bottle compatible).

Estimated Cost: $120,000–$300,000+

Built for commercial fertilizer manufacturers and agro-industrial zones. Features include: automated PLC-controlled fermentation system with 50m³+ tank, sterilization units (UV or low-temp) to stabilize microbial activity, automated CIP cleaning system to reduce contamination risks, integrated packaging line with multi-head fillers, bottle cappers, and labelers

How to add microbial agents in liquid biofertilizer production technology?

Adding microbial agents is an important step in liquid biofertilizer production technology. Microbial strains such as lactic acid bacteria, phosphate-solubilizing bacteria, and potassium-solubilizing bacteria can increase fertilizer efficiency and improve soil health. At the same time, you can customize different formulas by combining microbial agents with trace elements. To achieve this, YUSHUNXIN provides a special ingredient adding tank. This equipment is made of 304 stainless steel, equipped with an internal stirrer and a filtering system. It ensures uniform mixing, accurate dosing, and high product quality. Besides microbial agents, you can also add humic acid, NPK powder, or other nutrients in the same system.
