The solutions to make liquid npk biofertilizer are a High ROI business plan for fertilizer manufacturers. When you already have powdered NPK raw materials, turning them into a liquid NPK biofertilizer mainly involves four technical stages — raw water treatment, nutrient blending, chelation reaction, and liquid filling. In some cases, , you may also need a chain crusher to process minerals or solid raw materials. Each step is supported by specialized liquid biofertilizer production equipment to ensure product quality, stability, and biological activity.
Key equipment used in bio liquid npk fertilizer manufacturing
Preparing Raw Water and Crushed Materials
Clean and stable water is essential for liquid biofertilizer production. A water treatment system helps remove impurities and balance pH, ensuring that the water meets production standards. If your raw materials include granular NPK or mineral fertilizers, a chain crusher can pulverize them into fine powder. It will improves solubility and uniformity in the subsequent blending process.
Accurate Nutrient Dosing and Mixing–batching system
Once the water and base materials are ready, you can use an automatic batching machine to prepare powdered N, P, and K materials accurately. By setting the feed parameters, you can flexibly make liquid NPK biofertilizer. Depending on bio liquid npk fertilizer formulation, you can addtrace elements, amino acids…
Chelation Reaction for Nutrient Stabilization
Next, the raw materials enter the stainless chelating reaction tank for mixing. Made of 304 stainless steel, this tank is equipped with temperature control and an internal agitator. So, it allows elements like N, P, K, and trace minerals to react under controlled conditions. Chelation helps stabilize nutrients. The result is a uniform, high-performance liquid fertilizer solution ready for biological enhancement.
Adding Microbial Agents to Enhance Bioactivity
After the chelation stages,you can add beneficial microorganisms through an additive dosing tank. Common biological strains include Bacillus subtilis, Azotobacter, Rhizobium, and Trichoderma spp. The additive dosing tank is also made of 304 stainless steel. It ensures gentle and uniform mixing of microbial agents with a built-in stirring system. This step transforms a conventional NPK liquid fertilizer into a bioactive NPK fertilizer.
Storage and Liquid biofertilizer Filling– automatic filling machine:
Finally, the bio npk liquid fertilizer flows into a storage tank for temporary holding. Then, it moves to the liquid fertilizer filling machine, which ensures accurate, leak-free packaging. You can customize the filling system for different bottle requirements and capacities.
