1-3T/H Liquid Fertilizer Production Line

As sustainable agriculture becomes a global priority, farmers and fertilizer producers are seeking more efficient and environmentally friendly ways to deliver nutrients to crops. A 1-3T/H liquid fertilizer production line provides the perfect balance between productivity, cost-effectiveness, and flexibility. Designed for medium-scale operations, this production line is ideal for transforming organic materials, chemical compounds, or blended nutrients into high-quality liquid fertilizers that improve soil fertility and crop yield.


1. What Is a 1-3T/H Liquid Fertilizer Production Line?

A 1-3T/H liquid fertilizer production line is an integrated system designed to produce liquid fertilizers at a rate of 1 to 3 tons per hour. This line combines advanced mixing, filtration, and filling technologies to create fertilizers that can be applied directly through irrigation systems or foliar sprays.

Unlike solid fertilizers, liquid fertilizers dissolve quickly, offering rapid nutrient absorption and uniform distribution. This makes them ideal for high-efficiency farming systems, including hydroponic and precision agriculture setups.

2. Key Components of a 1-3T/H Liquid Fertilizer Production Line

A complete 1-3T/H liquid fertilizer production line consists of several essential units working together to ensure stability, accuracy, and quality:

Equipment NameFunction
Mixing TankBlends raw materials evenly under controlled temperature and agitation.
Heating SystemAdjusts temperature to promote chemical reactions and dissolve nutrients efficiently.
Filtration SystemRemoves impurities to ensure a pure and uniform fertilizer solution.
Storage TankStores the finished fertilizer before packaging or distribution.
Filling MachineAutomatically fills the fertilizer into bottles, drums, or IBC containers.
PLC Control SystemEnsures precise control of mixing ratios, temperature, and flow rates.

This setup guarantees stable production, precise formulation, and high product consistency — essential for both organic and chemical liquid fertilizers.

3. Production Process of the 1-3T/H Liquid Fertilizer Line

The production process can vary slightly depending on raw materials (organic or synthetic), but the general workflow is as follows:

Step 1: Material Preparation

Liquid fertilizers can be made from organic materials (such as compost extract, fish waste, or seaweed) or inorganic nutrients (N, P, K compounds).
Raw materials are tested and pre-measured before entering the mixing stage.

Step 2: Mixing and Dissolving

All ingredients are added into the stainless-steel mixing tank. The agitator and heating system ensure that nutrients are fully dissolved and uniformly blended.

Step 3: Filtration

The fertilizer mixture passes through a dual filter or centrifugal filtration unit to remove undissolved particles and impurities, ensuring product clarity and preventing nozzle blockage during spraying.

Step 4: Cooling and pH Adjustment

The liquid fertilizer is cooled to a stable temperature and the pH is adjusted to the desired range (typically 6.0–7.0) to maintain nutrient stability.

Step 5: Storage and Packaging

The finished fertilizer is stored in sealed stainless-steel storage tanks, then transferred to the automatic filling line. The PLC system ensures precise volume control for drums, bottles, or bulk containers.

4. Case Example: 1-3T/H Liquid Fertilizer Line in Southeast Asia

In Southeast Asia, a local agricultural enterprise has established a 1-3 ton per hour liquid fertilizer production line to meet the growing demand for efficient nutrient solutions from plantations and greenhouse cultivation. This project focuses on converting readily available local raw materials such as humic acid, amino acids, and seaweed extracts into high-quality liquid fertilizers. 

The production process includes automatic mixing, filtration and filling systems, ensuring the stable quality and consistent concentration of each batch of fertilizer. This production line is equipped with stainless steel mixing tanks, dual filtration units and a PLC control system for real-time monitoring and precise proportioning. 

Since its commissioning, this production line has been operating continuously with very low maintenance requirements, and the output of finished products has reached 3 tons per hour. Customers have reported that the nutrient utilization rate has increased by 30% and the production costs have significantly decreased. This case fully demonstrates how LANE's customized design and reliable equipment can help regional producers improve production efficiency and fertilizer quality.
