We extract this mineral-derived potassium fulvate powder from carefully selected high-quality natural lignite and weathered coal, and refine it through deep activation and concentration. Rich in highly active fulvic acid, potassium oxide, chelated trace elements, and small-molecule organic carbon, it is a green organic agricultural product that integrates soil improvement, root and seedling promotion, quality enhancement, yield increase, stress resistance, disease prevention, and fertilizer efficiency enhancement. It is widely applicable to field crops, vegetables, fruit trees, flowers, medicinal herbs, and cash crops, and is completely safe and residue-free, meeting green ecological planting standards.

I. Core Components

1. Mineral-derived fulvic acid ≥ 50%
2. Potassium oxide (K₂O) ≥ 12%
3. Small-molecule organic carbon and active functional groups
4. Chelated trace elements: calcium, magnesium, zinc, iron, boron, etc.
5. Character: Dark brown fine powder, fully water-soluble, impurity-free, fast dissolving

II. Main Functions

1. Improve soil and break compaction
2. Stimulate strong rooting and promote seedling growth
3. Enhance fertilizer efficiency and reduce waste
4. Improve crop quality and increase yield
5. Strengthen stress resistance and disease resistance
6. Alleviate pesticide and fertilizer toxicity

III. Suitable Crops

1. Field crops: wheat, rice, corn, cotton
2. Vegetables: cucumber, tomato, pepper, cabbage, onion, ginger, garlic
3. Fruits: apple, citrus, grape, strawberry, watermelon
4. Economic crops: flowers, seedlings, tea, medicinal herbs

IV. Application Methods

1. Fertigation / Drip irrigation: 7.5–15 kg per hectare per application, dilute with water and apply with irrigation. Use 2–3 times during the growth period.
2. Foliar spray: Dilute 1:1500–1:2000 and spray evenly. Repeat after 7–10 days, twice for best results.
3. Seed dressing / Root dipping: 5–10 g per kg of seeds for seed dressing. Dilute 1:500 for root dipping before transplanting to improve survival rate.
4. Base fertilizer: Mix with compound fertilizer or organic fertilizer at 7.5–15 kg per hectare.

V. Product Advantages

1. Higher activity, faster effect and longer persistence than biochemical fulvic acid.
2. Suitable for drip irrigation, sprinkler irrigation and fertigation; no clogging, no sediment.
3. No hormones, non-toxic, residue-free, compliant with organic farming standards.
4. Multiple benefits: soil improvement, rooting, yield increase, stress resistance and efficiency enhancement.

VI. Precautions

1. Store sealed in a cool, dry place. Avoid moisture. Caking does not affect product efficacy.
2. Can be mixed with most neutral and acidic fertilizers and pesticides for synergistic effect.
3. Use strictly at the recommended rate. Do not mix directly with strong alkaline substances.
