Key Product Features
- High Purity & High Activity: Extracted from premium mineral humic sources, free of heavy metals and harmful impurities, with high biological activity for quick absorption by soil and crops
- Excellent Solubility: Fully soluble in water with no insoluble residues, suitable for drip irrigation, sprinkler irrigation, foliar fertilization, and mixed applications
- Stable Performance: Resistant to hard water, not prone to flocculation or precipitation, compatible with most acidic, neutral, and alkaline pesticides and fertilizers
- Long-lasting Effect: Slowly releases nutrients in soil, improves soil buffering capacity, and provides sustained conditioning and fertilizing effects
Main Functions & Benefits
Soil Improvement
- Optimize soil aggregate structure, loosen compacted soil, and reduce soil salinization and acidification damage
- Enhance soil cation exchange capacity (CEC), improve water and fertilizer retention, and reduce nutrient leaching
- Stimulate reproduction and activity of beneficial soil microorganisms, accelerating organic matter decomposition
Promote Crop Growth
- Stimulate seed germination, increase germination rates and seedling survival, and promote robust root development
- Accelerate crop metabolism, promote photosynthesis, and advance maturity periods for increased crop yields
- Enhance crop stress resistance including drought, cold, disease, and lodging resistance
Improve Nutrient Utilization & Crop Quality
- Chelate and activate medium and trace elements, converting ineffective nutrients into available forms
- Improve fertilizer utilization rate by more than 30% through enhanced nutrient availability
- Reduce nitrate accumulation in crops while increasing vitamin C, sugar, and protein content
Application Scope
Suitable for various soil types and all crops including field crops (wheat, corn, rice, soybean), cash crops (cotton, tobacco, tea), vegetables (tomato, cucumber, pepper), fruits (apple, grape, citrus, strawberry), flowers, nursery stocks, Chinese medicinal materials, ecological restoration, lawn maintenance, and soilless cultivation.
Application Methods
- Soil Application: Mix with base fertilizer or topdressing, apply 15-30 kg per hectare via spreading, hole application, or furrow application
- Drip & Sprinkler Irrigation: Dissolve 1-2 kg per mu in water, apply with irrigation water 2-3 times during crop growth period
- Foliar Spraying: Dilute 800-1500 times with water, spray evenly on crop leaves 2-3 times at 7-10 day intervals
- Seed Soaking & Root Dipping: Dilute 1000-1500 times with water, soak seeds for 8-12 hours or dip roots for 10-20 minutes before transplanting
Packaging & Storage
Packaging: 25kg kraft paper bag with inner plastic film bag, customizable packaging available
Storage: Store in cool, dry, ventilated place away from direct sunlight and moisture; keep separate from food, feed, and seeds
