Humic Acid Liquid: The Organic Fertilizer Choice

Humic Acid Liquid Product Overview

Humic acid liquid is a high-quality organic fertilizer derived from naturally occurring humic substances in leonardite, lignite, or other organic deposits. Rich in humic and fulvic acids, it plays a vital role in enhancing soil fertility, promoting plant growth, and improving crop yield.

By improving soil structure and increasing nutrient availability, humic acid liquid helps plants absorb essential elements more efficiently. Its chelating properties also aid in reducing soil toxicity by binding heavy metals and other harmful substances. This makes it an ideal solution for sustainable agriculture, organic farming, and soil restoration.

Key benefits include:

Enhances Soil Health: Stimulates microbial activity and improves soil structure for better aeration and water retention.
Promotes Plant Growth: Encourages root development, increases nutrient uptake, and boosts plant resilience.
Increases Crop Yield: Improves overall crop quality and productivity.
Eco-Friendly Solution: Derived from natural sources, safe for the environment and long-term soil fertility.

Humic acid liquid is suitable for a wide range of crops, including fruits, vegetables, grains, and horticultural plants, providing a natural, efficient, and sustainable approach to modern agriculture.

Liquid Humic Acid FAQ

1. What is liquid humic acid, and how is it produced?

Liquid humic acid is a concentrated, water-soluble formulation derived from natural organic sources like leonardite, peat, or weathered coal. It is produced through advanced extraction processes— alkaline extraction—followed by purification to remove impurities. This results in a stable, high-active product rich in humic acids, fulvic acids, and trace minerals, designed for easy absorption by plants and soil.

2. How does liquid humic acid differ from solid humic acid powders?

Compared to solid powders, liquid humic acid offers several key advantages: it has 100% water solubility (no clumping or sedimentation), faster absorption by plant roots and foliage, and easier mixing with fertilizers, pesticides, or irrigation systems. It also eliminates the need for dissolving or grinding, reducing application time and ensuring uniform distribution in soil or on crops.

3. Which crops benefit most from liquid humic acid application?

Liquid humic acid is versatile and suitable for all crops, including field crops (wheat, corn, cotton), cash crops (fruits, vegetables, grapes), ornamental plants, and even hydroponic systems. It is particularly effective for crops grown in poor soil conditions (saline-alkaline, compacted, or low-organic-matter soils) as it improves soil structure and nutrient uptake.

4. What are the recommended application methods and rates?

Common application methods include:

Please refer to the «Recommended Dosage & Application Methods» section of this page.

5. Can liquid humic acid be mixed with other fertilizers or pesticides?

Yes, it is compatible with most water-soluble fertilizers (nitrogen, phosphorus, potassium), micronutrients, and non-alkaline pesticides. However, always perform a small compatibility test first: mix a small amount of liquid humic acid with the desired product, check for flocculation or precipitation, and proceed only if the mixture remains uniform.

6. How long does it take to see results after application?

Short-term effects (1-2 weeks) include improved seed germination, enhanced root growth, and darker green foliage. Long-term benefits (4-8 weeks) manifest as better soil aggregation, increased water retention, reduced nutrient leaching, and higher crop yield/quality. Results may vary based on soil conditions and application frequency.

7. Is liquid humic acid safe for the environment, crops, and humans?

Yes, when used as directed. It is an organic, non-toxic product derived from natural sources. It does not leave harmful residues on crops, is safe for beneficial soil organisms (earthworms, microbes), and complies with international organic standards (e.g., CERES, OMRI, ECOCERT). Avoid direct contact with eyes; rinse with water if contact occurs.

8. What is the shelf life of liquid humic acid, and how should it be stored?

Unopened, it has a shelf life of 24 months when stored in a cool, dry, and dark place (temperature 5-35°C). Avoid exposure to direct sunlight, extreme temperatures (below 0°C or above 40°C), and contamination. Once opened, seal tightly and use within 6 months for optimal efficacy.

9. How does liquid humic acid improve soil health?

It enhances soil health by:

Binding soil particles to form stable aggregates, improving aeration and water infiltration.
Chelating essential nutrients (iron, zinc, manganese) to make them more available to plants.
Stimulating the growth of beneficial soil microbes, which decompose organic matter and cycle nutrients.
Reducing soil salinity and heavy metal toxicity by forming complexes with harmful ions.

10. Can liquid humic acid be used in organic farming?

Absolutely. JINGFENG high-quality liquid humic acid products (already certified by CERES) meet the strict requirements of organic farming. They are free from synthetic additives and help maintain soil fertility without relying on chemical inputs, making them a key tool for sustainable organic agriculture.
