1、Review: Biotic and abiotic approaches to artificial humic acids
Humic acids (HAs) are a type of effective additives for enhancing soil fertility, but natural HAs reserves are limited. Artificial HAs can be produced from biomass by biotic composting and abiotic hydrothermal reaction (HTR).
2、How is humic acid produced? Principles of Humus Acid Production
Once produced, humic acid can be used in various agricultural applications, such as soil amendments, fertilizers, and plant growth stimulants. Its ability to improve soil structure, enhance nutrient availability, and promote plant growth makes it a valuable tool in sustainable agriculture.
3、How is humic fertilizer made?
Humic acid is produced through a process called humification. This process involves the breakdown of organic matter by microorganisms in the soil. The microorganisms break down the organic matter into smaller molecules, which are then further broken down into humic acid.
4、the process of making humic acid biofertilizer – BRSQ
This article explores the process of producing humic acid bio-organic fertilizer, offering insights into its development and application. Understanding Humic Acid. Humic acid is a principal component of humic substances, constituting a major fraction of soil organic matter.
5、Humic Acid Fertilizer Production
Humic acid can be produced as fertilizer in three forms: powder, liquid and granular, each with its own advantages. 1. Manufacturing process for humic acid powdered fertilizer: 1) Raw Material Preparation: Equipment: Crushers, grinders, or hammer mills.
Humic Acid Manufacturing Industry. Production of Humic Acid
Benefits of Humic Acid Throughout history, farmers have used humic acid to generate healthier plants and a higher crop yield. Today, humic acids are even more essential than ever, for the reasons mentioned above. Here are just a few of the many benefits of humic acid.
Humic Acid Fertilizer: What It Is and Its Key Benefits
Humic acid is a complex organic compound formed over millions of years through the decomposition of plant and animal matter. This process, known as humification, results in a stable, dark substance found in natural sources like peat, leonardite, and lignite.

Obviously, the carbon content is very high, This is why many manufacturers sell humic acids as a carbon fertilizer.
Humic Acid Fertilizer Uses: Role, Application Methods, Dosage, and
Humic Acid is formed through humification, which occurs when plant and animal matter breaks down in the Soil. It improves soil fertility and plant growth by increasing nutrient uptake and water retention, improving soil structure, and promoting microbial activity.
Advances and challenges in humic acid production technologies from
Hydrothermal conversion offers energy-efficient, high-yield humic acid production. Circular economy strategies for the artificial synthesis of humic acids are discussed.
Humic acid fertilizer is a nutrient-rich product derived from animal and plant residues through microbial fermentation. It contains essential nutrients such as nitrogen (N), phosphorus (P), and potassium (K), along with organic matter and beneficial microorganisms. These components enhance soil water-retaining capacity, improve soil structure, and promote plant growth. Below is a detailed explanation of its production process:
I. Raw Material Preparation
1. Raw Material Selection
- Animal Manure: Such as cow dung, chicken manure, and pig manure, which are rich in N, P, and K.
- Plant Residues: Including straw, fallen leaves, and weeds, which provide cellulose, hemicellulose, and lignin as carbon sources for microorganisms.
- Microbial Agents: Specific strains like nitrogen-fixing bacteria, phosphate-solubilizing bacteria, and composite microbial communities are added to accelerate decomposition.
2. Pretreatment
- Crushing: Animal manure and plant residues are crushed to facilitate mixing with microbial agents.
- Moisture Adjustment: Water content is adjusted to 40%–60% to ensure smooth fermentation.
II. Fermentation Process
1. Inoculation
- Microbial Agent Addition: Selected microbial agents are evenly sprinkled into the raw materials.
- Mixing: Raw materials and microbial agents are thoroughly mixed using a turning machine or manually to ensure uniform distribution.
2. Fermentation Condition Control
- Temperature: Maintained at 35°C–40°C; extreme temperatures hinder fermentation.
- Ventilation: Ensures oxygen supply and waste decomposition.
- Moisture Regulation: Periodically top up moisture to keep materials damp but not waterlogged.
3. Fermentation Duration
- Initial Stage: Bacterial activity peaks, rapidly decomposing organic matter with high temperatures.
- Mid-Later Stage: Fungi dominate, converting organics into humic acid; temperatures stabilize.
- Continuous Fermentation: Regular monitoring is required to address any abnormalities.
III. Post-Treatment and Packaging
1. Post-Treatment
- Filtration: Remove solid impurities from the fermented liquid.
- Concentration: Increase humic acid concentration by reducing liquid volume.
- Drying: Dry the concentrated liquid to obtain finished humic acid fertilizer.
2. Packaging
- Materials: Use plastic bags, woven bags, or other suitable packaging.
- Labeling: Include product name, ingredients, usage instructions, and shelf life.
- Storage and Transport: Seal packages tightly to prevent moisture and contamination; follow storage guidelines.
IV. Key Considerations
- Hygiene and Safety: Wear protective gear and maintain sanitation to avoid cross-contamination.
- Environmental Impact: Monitor gases like methane (CH₄) and hydrogen sulfide (H₂S) during fermentation.
- Quality Control: Rigorously manage fermentation conditions to ensure consistent product quality.
producing high-quality humic acid fertilizer requires meticulous attention to raw material selection, fermentation processes, and post-treatment. Adherence to standardized procedures guarantees optimal results.
