Potassium Humate Powder (HUWIN 100)

High Humic Acid + High Solubility + 100 Mesh Powder: A Convenient and Efficient Soil Amendment & Potassium Fertilizer

A scientific formulation of humic acid, fulvic acid, and potassium oxide, featuring high water solubility and 100 mesh powder form. This is not a simple combination of ingredients, but a deep synergy of "highly active soil improvement + efficient potassium supplementation + powder convenience". Leveraging its pH 9-10 alkaline characteristics, it leaves no residue, is easy to absorb, offers microbial compatibility and high cost-effectiveness. Suitable for various crops, acidic and saline-alkali soils, and adaptable to both large-scale and intensive cultivation needs, aligning with green agriculture standards.

1. Mutual Enhancement: Strengthened Activity and Absorption Efficiency. With humic acid content >65%, it effectively enriches soil organic matter, chelates NPK and trace elements, activates inert nutrients, reduces potassium oxide loss, and maintains nutrient balance. Fulvic acid retains its native biological activity, aiding root promotion and stress resistance. High solubility combined with 100 mesh powder ensures rapid, complete dissolution without residue, no need for prolonged stirring, and uniform nutrient release, significantly enhancing absorption efficiency. The 100 mesh powder specification allows flexible adaptation to different cultivation areas, achieving simultaneous "soil improvement, fertilization, and efficiency enhancement".

2. Soil Improvement: Targeted Adjustment and Universal Adaptability. The product maintains a stable pH of 9-10, alkaline in nature, which can specifically neutralize soil acidity, alleviate saline-alkali stress, and optimize soil physical and chemical properties. High-content humic acid acts as a natural binder, promoting the formation of soil aggregate structure, enhancing soil aeration, water and nutrient retention, and alleviating compaction. The 100 mesh powder ensures even distribution without localized accumulation when broadcast, suitable for large-scale field application and intensive greenhouse planting, achieving comprehensive soil improvement without precise operation.

3. Synergistic Root Promotion: Building a Strong Growth Foundation. The biological activity of fulvic acid stimulates root primordium germination and accelerates root growth. Humic acid optimizes the rhizosphere microecology, creating a suitable environment for root development. Potassium oxide strengthens root vitality and reduces premature aging. The high solubility allows nutrients to rapidly penetrate the root zone. The synergy of these three components helps crops develop robust root systems in adverse soils, enhancing water and nutrient uptake capacity, meeting crop growth needs throughout the entire growth cycle.

4. Stress Resistance Enhancement: Stable Yield and Scenario Adaptability. The synergy of high-content humic acid and fulvic acid regulates crop metabolism, significantly improving drought tolerance, salt tolerance, cold tolerance, and disease resistance, reducing yield loss caused by environmental stress, and ensuring stable production.

5. Quality and Efficiency Improvement: High Cost-Effectiveness and Convenient Control. High solubility enhances nutrient utilization efficiency, while high-activity components achieve "low dosage, high effect", balancing quality improvement and cost control. Potassium oxide strengthens crop stem toughness and improves fruit quality. Long-term application can reduce chemical fertilizer usage. It can also serve as an excellent blending component for organic fertilizers and biostimulants.

Expert Advice: Suitable for all crop growth stages, particularly adaptable to large-scale field cultivation, acidic soil improvement, and saline-alkali land remediation. For basal application, broadcast evenly and then plow under; for fertigation, dissolve in advance; the 100 mesh powder will not clog pipes after dissolution. It can be flexibly combined based on cultivation area. Using with microbial fertilizers can enhance microbial efficacy, further improving soil fertility and crop yield.

1

The product has a pH of 9-10, making it alkaline. Which soils and crops is it suitable for?

Suitable for acidic soils (pH < 6.5) and slightly acidic soils (pH 6.5-7.0). It can improve acidified soils caused by continuous greenhouse cropping or long-term chemical fertilizer application. Suitable for field crops like wheat, corn, rice; fruit trees like citrus, apple, grape; vegetables like tomato, pepper, and root/tuber crops. Not suitable for alkaline soils (pH > 7.5) or saline-alkali land. Avoid direct mixing with strongly acidic fertilizers like ammonium sulfate or monopotassium phosphate to prevent neutralization reactions that reduce efficacy. If combined application is desired, maintain a 3-5 day interval between applications.
