Humic acid liquid fertilizer production plant technology is rapidly reshaping the future of sustainable agriculture. As farmers and agribusinesses shift from traditional chemical fertilizers toward natural, bio-based solutions, humic acid has emerged as one of the most valuable organic components for soil improvement and plant nutrition. A well-designed humic acid liquid fertilizer production plant can convert organic carbon materials into a high-value nutrient solution that enhances soil fertility, boosts root development, and improves crop yields — all while protecting the environment.

Understanding Humic Acid and Its Agricultural Value
Humic acid is an organic substance naturally formed during the decomposition of plant and animal matter. It is rich in carbon and functional groups that improve soil structure, increase water retention, and stimulate beneficial microbial activity.In agriculture, humic acid liquid fertilizer is prized for its dual benefits: it enriches the soil while enhancing plant metabolism and nutrient absorption. Unlike chemical fertilizers that may degrade soil health over time, humic acid fertilizers build long-term fertility and balance soil pH, creating a sustainable growing environment.
Humic acid is often extracted from lignite, peat, or leonardite, which contain high concentrations of humic substances. Through advanced liquid processing systems, these raw materials can be transformed into a highly soluble and efficient fertilizer suitable for all types of crops — from cereals and vegetables to fruit trees and ornamental plants.
Raw Materials Used in a Humic Acid Liquid Fertilizer Production Plant
To produce humic acid liquid fertilizer, the choice of raw material directly determines product quality and nutrient concentration. Common raw materials include:
Leonardite (Oxidized Lignite): The most concentrated source of humic acid, usually containing 60–80% humic substances.
Peat and Compost: Contain organic acids and beneficial microorganisms, suitable for blending and fermentation.
Plant Residues: Agricultural waste such as rice husk, corn stalks, or fruit pulp can be used as organic carbon sources.
Additives: Nutrient enhancers such as nitrogen, potassium, amino acids, or seaweed extract can be incorporated to create functional formulations.
By integrating different organic materials, manufacturers can produce multi-functional liquid fertilizers tailored for specific crops or soil conditions.
Key Equipment in a Humic Acid Liquid Fertilizer Production Plant
The efficiency and quality of production depend largely on the design of the equipment line. A complete humic acid liquid fertilizer production plant typically includes the following machines and processing units:
Raw Material Fermentation Tank: For biological fermentation and breakdown of organic matter into simpler nutrients.
Mixing and Reaction Tanks: Where humic acid extraction and neutralization take place using mild alkaline solutions.
Filtration System: Removes insoluble residues to ensure a clear and stable liquid product.
Evaporation and Concentration Units: Adjust the solid content and viscosity of the final fertilizer.
Automatic Filling Machine: For packaging the humic acid liquid fertilizer into bottles, barrels, or IBC tanks.
Storage and Circulation Systems: Maintain product homogeneity and prevent sedimentation during storage.
LANE Heavy Industry offers integrated equipment lines for humic acid liquid fertilizer production plants, combining efficient mixing systems, stainless steel reaction vessels, and intelligent control systems. These allow continuous production with precise temperature and pH monitoring, ensuring consistent product quality and cost efficiency.
Production Process of Humic Acid Liquid Fertilizer
The manufacturing process generally follows a continuous-flow approach designed for efficiency and environmental safety. The typical workflow is as follows:
Raw Material Preparation: Leonardite or organic compost is crushed and screened to remove impurities.
Extraction and Reaction: The material is reacted with a mild alkaline solution (such as potassium hydroxide) in a reaction tank, releasing soluble humic acid.
Filtration and Purification: The resulting slurry is filtered to separate solid residues, producing a clean humic extract.
Nutrient Blending: Additional nutrients (N, P, K, amino acids, trace elements) are added to enhance fertilizer efficiency.
pH Adjustment and Stabilization: The formula is balanced to maintain product stability and shelf life.
Packaging and Storage: The final product is filled, sealed, and stored under controlled conditions.
LANE’s automated production systems enable users to control each step digitally, minimizing human error and maximizing production yield.

Benefits of Humic Acid Liquid Fertilizer
The growing demand for humic acid liquid fertilizer stems from its wide range of agricultural advantages:
Improved Soil Structure: Humic acid increases soil porosity and aeration, promoting better root penetration.
Enhanced Nutrient Uptake: It chelates essential nutrients, making them more available to plants.
Water Retention: Helps soils retain moisture, reducing irrigation needs.
Microbial Activity Boost: Encourages beneficial microorganisms that support plant growth.
Stress Resistance: Increases plant tolerance to drought, salinity, and disease.
Eco-Friendly Fertilization: Reduces reliance on synthetic fertilizers and mitigates soil degradation.
When applied through drip irrigation or foliar spraying, humic acid liquid fertilizers show quick and visible effects on plant vigor, leaf color, and root development.
Market Outlook and Opportunities in Humic Acid Liquid Fertilizer Production
The global market for humic acid liquid fertilizer production plants is expanding rapidly, particularly in regions focusing on organic farming, sustainable agriculture, and soil restoration.Countries across Southeast Asia, Africa, and Latin America are seeing increasing adoption as farmers seek to improve soil productivity in a cost-effective, environmentally friendly manner.
According to recent agricultural data, the global demand for humic substances in fertilizers is expected to exceed US$1.5 billion by 2027, with liquid formulations growing faster than granular products.
For equipment manufacturers and investors, setting up a humic acid liquid fertilizer production plant offers long-term benefits — stable raw material supply, broad market potential, and compatibility with local organic resources such as compost, peat, or biochar.
