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.

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 alkaline extraction followed by purification to remove impurities, resulting in a stable, high-active product rich in humic acids, fulvic acids, and trace minerals.
2. How does liquid humic acid differ from solid humic acid powders?
Compared to solid powders, liquid humic acid offers 100% water solubility (no clumping or sedimentation), faster absorption by roots and foliage, and easier mixing with fertilizers, pesticides, or irrigation systems — reducing application time and ensuring uniform distribution.
3. Which crops benefit most from liquid humic acid application?
It is versatile and suitable for all crops — field crops (wheat, corn, cotton), cash crops (fruits, vegetables, grapes), ornamental plants, and even hydroponic systems. Particularly effective for poor soils (saline-alkaline, compacted, low-organic-matter).
4. What are the recommended application methods and rates?
Common methods include soil application, foliar spray, substrate, seed treatment, and hydroponic. 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 and non-alkaline pesticides. Always perform a small compatibility test first: mix a small amount, check for flocculation or precipitation, and proceed only if uniform.
6. How long does it take to see results after application?
Short-term (1–2 weeks): improved germination, enhanced root growth, darker green foliage. Long-term (4–8 weeks): better soil aggregation, increased water retention, higher yield/quality.
7. Is liquid humic acid safe for the environment, crops, and humans?
Yes, when used as directed. It is organic, non-toxic, leaves no harmful residues, is safe for beneficial soil organisms, and complies with CERES / OMRI / ECOCERT. Avoid direct eye contact.
8. What is the shelf life, and how should it be stored?
Unopened shelf life is 24 months when stored cool, dry, and dark (5–35°C). Avoid direct sunlight and extreme temperatures. Once opened, seal tightly and use within 6 months.
9. How does liquid humic acid improve soil health?
It binds soil particles into stable aggregates, chelates iron/zinc/manganese for plant availability, stimulates beneficial microbes, and reduces salinity and heavy-metal toxicity by complexing harmful ions.
10. Can liquid humic acid be used in organic farming?
Absolutely. JINGFENG high-quality liquid humic acid products (certified by CERES) meet strict organic farming requirements — free from synthetic additives, maintaining soil fertility without chemical inputs.
