Humic Acid Powder CAS 1415-93-6

Agriculture represents the largest application scenario of humic acid powder and serves as a fundamental substrate for ecological agriculture. Compatible with all types of food crops, fruits, vegetables, seedlings and cash crops, it exerts integrated effects on soil improvement, fertilizer efficiency boosting and stress resistance & quality improvement of crops.For soil amelioration, NHA optimizes soil aggregate structure, loosens compacted soil, and enhances water and nutrient retention of sandy soil. It also balances soil pH, rehabilitates saline-alkali and acidified land, and alleviates secondary salinization in greenhouse cultivation.

Its unique chelating structure passivates heavy metals including lead, cadmium and chromium in soil, blocks their uptake by crops, and effectively remediates contaminated farmland. Furthermore, it supplies organic carbon sources for beneficial soil microbes, activates microbial activity, accelerates decomposition of soil organic matter, and sustainably improves soil fertility.

In terms of fertilizer efficiency improvement, NHA complexes nitrogen, phosphorus, potassium as well as secondary and trace elements like calcium, magnesium, zinc and iron. It drastically reduces nutrient leaching and improves fertilizer utilization rate, enabling a 15%–20% reduction in chemical fertilizer application and preventing soil compaction and acidification caused by long-term chemical fertilization.

It is commonly used as a raw material to produce humic acid water-soluble fertilizers, chelated trace element fertilizers and organic fertilizers.For crop care, dilute humic acid solution can be used for seed soaking to raise germination rates and stimulate root development at seedling stage. Foliar spraying boosts crop photosynthesis, accelerates accumulation of sugars and proteins to improve fruit flavor and appearance, and strengthens crop tolerance against drought, waterlogging and low temperatures. It also helps prevent soil-borne diseases such as root rot and verticillium wilt. When combined with pesticides, it enhances pesticide efficacy and degrades pesticide residues.

Purified and activated feed-grade NHA functions as a safe antibiotic-free farming additive that can partially replace antibiotics. Widely used in livestock breeding and aquaculture, it improves product quality, lowers disease incidence and cuts pollution emissions.In livestock farming, adding it to feed at a ratio of 0.1%–0.2% adsorbs harmful toxins and pathogenic bacteria in animal intestines, repairs intestinal mucosa, balances intestinal microflora, and significantly reduces the incidence of diarrhea, gastroenteritis and other ailments in young animals.

It facilitates absorption and utilization of proteins and minerals by livestock, elevates feed conversion ratio, accelerates weight gain of broilers and pigs, improves egg laying rate and shell quality of laying hens, and optimizes milk quality of cattle and sheep. In addition, it adsorbs harmful gases including ammonia and hydrogen sulfide in livestock manure, mitigates unpleasant odors on farms and curtails farming pollution discharge.

In aquaculture, NHA acts as an efficient substrate conditioner. It decomposes organic waste such as residual feed and feces in ponds, rapidly adsorbs ammonia nitrogen, nitrites, heavy metals and other hazardous substances in water bodies, stabilizes water pH and restores black and odorous water. It provides organic carbon for beneficial algae and plankton to cultivate balanced algal flora, raises dissolved oxygen levels, suppresses outbreaks of cyanobacteria and moss, alleviates aquaculture stress response, and lowers mortality of aquatic products including shrimp, crabs and sea cucumbers. Mixed into feed for feeding, it effectively prevents common aquatic diseases such as gill rot and enteritis.

Thanks to its superior porous adsorption capacity and ion exchange performance, NHA is a low-cost eco-material for environmental remediation, mainly deployed in soil restoration and water treatment.For soil remediation, beyond farmland improvement, it is applied to mine greening, industrial contaminated site rehabilitation and desertification control. By chelating and passivating heavy metals, it reduces the biological toxicity of soil pollutants, optimizes soil matrix, creates favorable conditions for vegetation growth, and achieves ecological land restoration alongside sand fixation and water retention.

In water treatment, NHA is used for industrial wastewater treatment and ecological maintenance of natural water bodies. For wastewater generated from electroplating, printing and dyeing, and aquaculture industries, it works as a flocculant and adsorbent that rapidly precipitates suspended solids, traps heavy metal ions and organic contaminants, lowers water COD values and purifies sewage at a far lower cost than traditional resin and water treatment chemicals. It also treats black and odorous rivers and lakes and maintains constructed wetlands, restraining water eutrophication, degrading water pollutants, boosting natural water self-purification capacity and rehabilitating aquatic ecosystems.

Modified humic acid powder features strong chemical stability and serves as a versatile auxiliary across numerous industrial sectors including petroleum, building materials, ceramics and metallurgy.In petroleum drilling, sulfonated modified NHA is a premium drilling mud additive with high temperature resistance, borehole collapse prevention and fluid loss control effects. It stabilizes well walls, reduces mud filtration loss, and improves the safety and efficiency of drilling operations.In the building materials industry, it acts as a cement water reducing agent and coal water slurry dispersant to enhance slurry fluidity and cut water consumption. It also serves as a briquette binder to strengthen coal briquette hardness and mitigate dust pollution from coal combustion.

In ceramic manufacturing, NHA works as a plasticizer and diluent for clay bodies, improving clay plasticity, reducing auxiliary dosage, effectively lowering the risk of green body cracking during firing and raising the qualified rate of finished ceramic products.In metallurgy and new energy sectors, it is a non-toxic mineral flotation depressant and rare earth metal precipitant to boost mineral separation efficiency. Meanwhile, it is a core expander for lead-acid batteries, optimizing electrode plate performance and extending battery cycle life. Besides the above scenarios, it is also applied in boiler circulating water scale inhibition, rubber anti-aging treatment, ink dispersion and coloration, featuring extensive application scope and strong practicality.

High-purity refined NHA with low heavy metal content is applicable to cosmetics, personal care, physical therapy and wellness industries.In skincare, its abundant active ingredients eliminate skin free radicals, inhibit photoaging and fade fine lines, while delivering potent anti-inflammatory and soothing effects to relieve redness and inflammation of sensitive skin.

Leveraging its excellent adsorption capacity, it binds excess sebum, dirt and trace heavy metals on the skin surface, and is frequently incorporated into mud masks, body wash and scalp care products to deliver dual effects of cleansing and skin repair.In physical therapy and wellness, it is a core raw material for traditional mineral baths and mud baths. It helps improve skin condition and relieve physical fatigue when used externally; it repairs superficial wounds and alleviates skin discomfort, with safe application and remarkable nourishing effects.
