Compared with the production of liquid fertilizer from manure, the liquid NPK fertilizer manufacturing process includes raw material proportioning, water source filtration, dissolution, chelation, filtration, and filling. So, it is suitable for liquid fertilizer companies that purchasing high ROI. We can provide the complete NPK liquid fertilizer production line for you, which consists of automatic batching system, chelation tank integrating stirring, heating and filtering, auxiliary material adding tank, liquid filling machine. By setting the batching system, you can produce NPK liquid fertilizers with different formulations, such as: 20-20-20，10-5-40, 15 0 0 liquid NPK fertilizer.
Get SolutionA modern liquid fertilizer production line allows you to process far more than manure. By using diverse nutrient-rich materials, you can expand your product range, reduce costs, and create formulas for specific crop needs.
Nutrient-dense by-product from anaerobic digestion, ideal for quick fermentation and blending.
Packed with amino acids and trace minerals, supports strong root growth and soil improvement.
Enhances nutrient absorption, improves soil structure, and stimulates plant metabolism.
In most liquid fertilizer production processes, the complete cycle takes about 3–5 days from raw material preparation to storage. Fermentation time depends on temperature, nutrient balance, and microbial activity. You can fine-tune these factors to optimize liquid fertilizer production.
In liquid fertilizer fermentation, the microbial inoculant plays a decisive role in organic matter decomposition and nutrient transformation. So you can add some beneficial agent to accelerate liquid fertilizer manufacturing process. Such as compound Bacillus, compound yeast, compound lactic acid bacteria, and compound enzyme preparations. Typically, 1 kg of microbial agent can ferment 250–500 liters of liquid fertilizer. The specific dosage depends on your raw material composition, desired fermentation speed, and nutrient requirements.
The suitable temperature of liquid fertilizer anaerobic fermentation is between 30 ℃ and 40 °C (86–104 °F). At the tempetature, the decompostion of organic matter and the growth of microorganisms are relatively faster. So, you can add the liquid heating tanks in the liquid fertilizer manufacturing plant, which is the key equipment in the step. By managing temperature and microbial conditions, you can keep liquid biofertilizer production efficient while delivering a stable, high-quality product.
