Liquid Fertilizer Production Line
ProTrus builds turnkey liquid fertilizer production lines for NPK solutions, suspension, foliar and organic fertilizers—combining accurate raw material dosing, corrosion-resistant mixing, homogenization and automated filtration in one scalable plant.

High-Efficiency Liquid Fertilizer Manufacturing
A liquid fertilizer production line dissolves, mixes and conditions nutrient raw materials into stable, ready-to-fill solutions or suspensions. ProTrus designs complete plants for clear NPK solutions, micronutrient and chelated blends, foliar fertilizers, amino acid and humic-based biostimulants, and organic liquid fertilizers.
Accurate dosing and controlled dissolution keep nutrient content on specification and prevent crystallization or settling in the container. Our lines combine automatic dosing, high-efficiency agitation, temperature and pH control, homogenization and inline filtration, so every batch leaves the plant consistent and easy to apply.
Turnkey Fertilizer Plant with Smart Automation
From project planning to commissioning, ProTrus delivers your liquid fertilizer plant as one integrated package: process design and 3D layout, tanks and mixers, dosing skids, piping, filtration, the filling interface and the control system. Recipes, batch records and alarms are managed from a central PLC/SCADA station, and the plant is sized to grow with your product range.

Corrosion-Resistant and CIP-Ready Design
Fertilizer solutions can be highly corrosive, so material selection is engineered for each formulation. Liquid-contact parts are built from acid- and alkali-resistant AISI 316 stainless steel, and alternative corrosion-resistant materials can be specified for aggressive recipes. Integrated CIP (Clean-in-Place) circuits allow fast product changeovers and prevent cross-contamination between nutrient grades.
What Is a Liquid Fertilizer Production Line?
It is an integrated system that turns solid and liquid raw materials—such as urea, ammonium and potassium salts, phosphoric acid, micronutrient salts, chelates, amino acids or humic extracts—into a homogeneous liquid product. Compared with granular fertilizers, liquid fertilizers are easy to blend, apply uniformly through fertigation and foliar spraying, and can be tailored to specific crops and growth stages.
Liquid Fertilizers You Can Produce
- Clear NPK solutions and straight N, P or K solutions
- Suspension fertilizers with high nutrient concentration
- Micronutrient and chelated (EDTA, DTPA, EDDHA) formulations
- Foliar fertilizers and biostimulants
- Amino acid, humic and fulvic acid products
- Organic liquid fertilizers
How the Liquid Fertilizer Production Process Works
- Water treatment and raw material intake: Process water is treated, and solid and liquid raw materials are stored and conveyed to the dosing area.
- Dosing: Each ingredient is weighed or metered automatically according to the recipe.
- Dissolving and reaction: Agitated tanks dissolve solids and, where required, control heat-releasing or heat-absorbing reactions with heating or cooling jackets.
- Homogenization: Suspension products are homogenized to keep particles finely dispersed and prevent settling.
- pH and quality adjustment: pH, density and nutrient content are checked and corrected before release.
- Filtration: Inline filters remove insolubles to protect drip and spray equipment.
- Storage and filling: The finished product is transferred to storage tanks and then to bottle, jerrycan, drum or IBC filling.

Frequently Asked Questions About Liquid Fertilizer Production Lines
What types of liquid fertilizer can one line produce?
A single ProTrus line can produce clear NPK solutions, micronutrient and chelated blends, foliar fertilizers, biostimulants and organic liquid fertilizers. Recipe-based automation and CIP cleaning make it practical to switch between products on the same equipment.
Which materials are used for corrosive fertilizer formulations?
Liquid-contact parts are typically built from AISI 316 stainless steel. For strongly acidic or chloride-rich formulations, ProTrus reviews the recipe and specifies alternative corrosion-resistant materials where needed.
Should I choose batch or continuous fertilizer production?
Batch production suits plants with many formulations and frequent changeovers, while continuous production fits high volumes of a few standard products. ProTrus recommends the right concept after reviewing your product range and target output.
Can the line include filling and packaging?
Yes. The line can be integrated with filling machines for bottles, jerrycans, drums or IBCs, so products move directly from storage tanks to packaging.
