What is Humic Acid?
Highassay’s Humic Acid is a highly active organic substance extracted from natural lignite.It is primarily used as a soil amendment, fertilizer synergist, and crop growth promoter. Our Humic Acid products are available in both solid and liquid forms to meet the needs of various application scenarios.

Forms of Humic Acid
Humic Acid Powder
Humic Acid Granules
Humic Acid Liquid
Yes. Using Humic Acid and Fulvic Acid together creates a complementary effect, providing long-lasting soil nourishment and rapid growth promotion without adverse reactions. It’s a common compounding solution in agriculture and organic farming.
Ordinary Humic Acid Powder is suitable for spreading or mixing with fine soil, organic fertilizer, or chemical fertilizer and then applying as a base fertilizer. This powder is insoluble in water, so it cannot be used for fertigation or foliar spraying.
Humic Acid Powder is finer and more suitable for mixing with soil or spreading. Humic Acid Granules are less dusty, easier to apply, and have a longer-lasting fertilizer effect compared to powder.
Benefits of Humic Acid
Improve soil structure & water retention:Directly applying Humic Acid to the soil helps improve soil aeration and permeability while retaining moisture, thereby alleviating issues such as soil compaction and poor water retention.
Boost fertilizer efficiency:Humic Acid activates soil nutrients such as nitrogen, phosphorus, and potassium; when used in conjunction with conventional chemical fertilizers, it allows for a 10%–30% reduction in application rates, thereby lowering costs while maintaining crop yields.
Enhance crop yield & quality:Humic Acid has an obvious effect in enhancing the plant’s nutrient absorption capacity and stress resistance (drought resistance, cold resistance, etc.), making your crops more productive and of higher quality.
Alleviate soil salinity & acidity:Soils can suffer from acidification and salinization; our high-quality, low-sodium Humic Acid helps buffer soil pH, creating ideal conditions for cultivation.
Applications of Humic Acid
Humic Acid for Agriculture is a vital organic additive used for a wide range of field crops, vegetables, and fruits; it not only ensures crop yields but also improves the flavor of the produce, thereby enhancing its commercial value.
Humic Acid for Horticulture is a highly effective biostimulant that activates the plant’s physiological activity, promoting robust and flourishing root systems in flowers and turf, while maintaining a vibrant, healthy, and attractive appearance over the long term.
Humic Acid for soil remediation can through comprehensive physical and chemical restructuring, degraded soil is gradually transformed into a healthy ecosystem, better meeting the requirements for the long-term maintenance of cultivated land.
Sources of Humic Acid Production
The sources of Humic Acid Production fall primarily into two categories:
Mineral-derived Humic Acid (mainstream in the industry):Humic acid is derived from peat, lignite, and weathered coal through separation and purification, and is classified as a non-renewable resource.Characterized by high molecular weight, an abundance of active groups, and a stable structure, it serves as a primary raw material for agricultural fertilizers.It is also the mainstream method we use to produce humic acid.
Biogenic Humic Acid (artificially fermented):It is a renewable resource and produced by fermenting organic wastes,including straw,bagasse,food waste.Compared with mineral-derived humic acid, bio-derived humic acid has a lower molecular weight, lower stability, and lower content, resulting in a weaker soil improvement effect.
